ACER CAMPESTRE Pianta spontanea (Europa, Asia). Alt. fino a 15m, diam. chioma fino a 6m.

Portamento sferico, irregolare. A lento sviluppo. Corteccia grigio - bruna.

Foglia palmata, costituita da 3 - 5 lobi, di colore verde scuro, gialla in autunno. Fiore giallo a Maggio. Frutto a samara, con ali allargate quasi a 180°, di colore rossiccio. Vegeta in qualunque terreno, soprattutto calcareo. Resistente all'inquinamento e alla siccità. Sopporta bene le potature. Rustica (-30° / -20°C).

Impiego: siepi di campagna, cortine verdi, gruppi. Decorativa soprattutto in autunno.

Characteristics A medium-sized native tree with a bushy, rounded head which can grow 15m (50ft) tall in good conditions though often stays smaller. The small leaves are of typical maple shape, though more rounded than some in the Acer family.

The autumn colour is a striking butter-yellow, and is one of the best from trees native to the British Isles. When young, bark has a curious cork-like appearance though as the tree matures this disappears.

Where to grow Field Maple will grow on most sites though it is especially happy on shallow soil over limestone and for this reason is very at home in Southern England where it is commonly found at field edges and as a standard tree. It also makes a wonderful hedging plant and is nearly as common in native countryside hedges as Hawthorn or Blackthorn. The reason for this is that it will take fairly severe cutting. It can also be laid, helping to create a strong stock proof hedge.

ACER NEGUNDO VARIEGATUM – FLAMINGO - AUREOMARGINATUM ACER NEGUNDO Pianta decidua Alt. fino a 12 - 15m, diam. chioma fino a 6 - 8m. Portamento sferico espanso. Crescita rapida. Corteccia grigio - bruna. Foglie composte da 3 - 5 foglioline di colore verde chiaro brillante. Fiore pendulo, di colore giallastro, sui rami in primavera prima delle foglie. Frutto a samara, ad ali strette, riunito in gruppi penduli. Vegeta in qualunque terreno, ma non calcareo.

Resistente alla siccità. Rustica (-30° / -20°C). Impiego: gruppi, alberature stradali.

ACER NEG. VARIEGATUM Simile a A. negundo. Piccolo albero. Alt. 7 - 8m, diam. chioma 4 - 5m. Fogliame parzialmente macchiato o marginato di bianco crema. Impiego: piccoli giardini, isolata, viali, alberature stradali. Resistente all'inquinamento.

ACER NEG. AUREOMARGINATUM Simile a A. negundo 'Argenteovariegatum'. Foglia bordata di giallo - oro.

Characteristics A variegated form of the Box Elder this is a small deciduous tree that will reach 7m (22ft) when mature and is a good choice for small gardens.

The variegated pinnate leaves consist of leaves with a yellow-white coloured margin, this cultivar is a small to medium-sized tree or shrub, often with several stems, whilst the pale grey of the branches look attractive in winter. Prone to shooting from the base it can be grown as a large shrub, though its ultimate shape will be oval.

Where to grow It will grow well in full sun or light shade and can cope with most soils though it likes free draining ground. For the best displays of foliage occur when it has been pruned back hard in the winter. Like many variegated trees it is prone to reversion, so any branches with purely green leaves will need to be removed completely. (-30° / -20°C)

ACER PLATANOIDES Pianta spontanea (Europa, Norvegia).

Alt. fino a 25m, diam. chioma fino a 8 - 10m. Portamento sferico espanso, chioma regolare, fitta. Crescita rapida. Corteccia grigio - bruna.

Frutto a samara divaricata. Vegeta in qualunque terreno, ma non calcareo.

Adatta ai climi di montagna.

Resistente all'inquinamento. Molto rustica (meno di -30°C). Impiego: viali, alberature stradali.

Characteristics There are few trees that have produced more varieties under cultivation than the Norway maple.

This large, fast-growing, elegant tree can grow up to 30m (100ft) in height. Its five lobed deep green leaves, similar to that of sycamore, change colour in autumn to orange and yellow with occasional hints of red. A favourite for planting in towns and cities across the UK as it is very tolerant of pollution. Its wonderful shape also makes it popular for planting in parks and country estates.

Where to grow It will grow well on most soil types, unless waterlogged or overly acidic. It is tolerant of very limey soils. Due to its large size it needs a lot of space to reach its full potential. It is also very happy on exposed windy sites.

(-30°C)

ACER PLATANOIDES CRIMSON KING

Characteristics A ruby red to purple leaved cultivar of the Norway Maple, Acer platanoides Crimson King is a fast growing medium sized tree. If given the space it can grow to more than 15m (50ft) in height with an oval shaped crown that can almost be as wide as it is tall.

The most noticeable and striking feature are its stunning deep purple 5 lobed leaves, that are of classic maple shape. It is a great tree for screening and contrasts well with trees of bright foliage such as Acer platanoides 'Drummondii', and for this reason these two trees are often planted together.

Albero deciduo Alt. 10 - 15m, diam. chioma 5 - 6m. Portamento sferico o a ceppaia. Foglia molto decorativa rosso porpora a primavera, che in autunno diventa arancione. Adatto ai climi di montagna.

Resistente all'inquinamento. Rustico (-30째 / -20째C). Impiego: isolato, viali.

ACER PLAT. DRUMMONDII

Where to grow It requires full sun or light shade and will grow on most soil types, with the exception of overly acidic sandy soils. It is a very hardy tree that will tolerate a lot of wind. Also a good choice for cities as it copes well with pollution. (-30째/-20째 C)

ACER PSEUDOPLATANUS Piante spontanee (Europa, Asia). Alt. fino a 25m, diam. chioma fino a 12m (è il più grande acero europeo).

Portamento sferico espanso, chioma fitta. Crescita rapida, media longevità (fino a 200 anni). Corteccia grigiastra. Grande foglia palmata, costituita da 5 lobi appuntiti e dentati, di colore verde scuro, un poco più chiara e ricoperta di peluria sulla pagina inferiore, che in autunno si colora di giallo oro. Fiore pendulo, giallo - verdastro, che compare sui rami in Aprile - Maggio contemporaneamente alle foglie.

Frutto a samare, leggermente divaricate (fino a 90°). Vegeta in qualunque terreno, anche moderatamente calcareo. Resistente ai venti, al freddo, alla neve e alla salsedine. Adatta ai climi di montagna. Resistente all'inquinamento. Molto rustica (meno di -30°C). Impiego: forestazione, gruppi, viali.

Characteristics Capable of reaching well over 25m (80ft), this fastgrowing large tree requires a lot of space. It is one of the best trees for exposed sites and coastal areas, growing in almost any conditions. When mature it provides a grand, domed outline in the countryside. Its dense leaves cast a heavy shade making it useful in fields with livestock. Not native to Britain, the Sycamore has become become naturalized since its introduction many centuries ago.

Where to grow Acer pseudoplatanus can grow almost anywhere. It is very happy with poor soil, windy and cold sites. It very easily self seeds and is often the first tree to establish itself on disused farmland and cleared woodlands. (-30°C)

ACER SACCHARINUM

Characteristics Growing to a mature height of 25m (80ft) this large, fast-growing tree is often found in parks and in large estates. The silver undersides to the classic maple shaped leaves make the tree appear white in windy weather. It has a good autumn colour display of rich gold/yellow. In its native North America the autumn colour can range from yellow and orange through to deep red, sadly due to the different climate here in the UK we virtually never see the full spectrum of colours.

Where to grow A good tree for urban sites as it tolerates pollution well, though due to its brittle branches it is not so good in exposed sites. It will grow in all but the worst soil and will do well in damp ground. Due to its large stature it needs a lot of space to grow and is not a good choice if space is limited. (-30° C)

Pianta a foglia caduca Alt. fino a 25m, diam. chioma fino a 8 - 10m. Portamento sferico ovoidale o a ceppaia, chioma irregolare. Crescita molto rapida. Corteccia grigiastra, piuttosto liscia da giovane. Foglia palmata costituita da 3 - 5 lobi seghettati e appuntiti, di colore verde medio superiormente e argentata sulla pagina inferiore, che diventa gialla in autunno. Fiore giallo - verde, sui rami all'inizio della primavera. Predilige i terreni freschi e molto umidi, non troppo calcarei. Resistente all'inquinamento.

Impiego: isolata, alberature stradali. Resiste all'inquinamento

ALNUS GLUTINOSA Pianta a foglia caduca, a portamento prevalente arboreo, raggiunge anche i 2025 metri di altezza, diffusa per la sua resistenza all’acqua nelle depressioni umide delle aree alluvionali o lungo sponde basse di rive o fiumi o in zone dove sia necessario un consolidamento del terreno.

Abbastanza rustica (-20°/15°C)

Characteristics Italian Alder is a large fast growing tree with glossy heart shaped leaves which grows to a height of 25m (80ft).

The shape is generally conic or pyramidal and the leaves very dense giving it the appearance of a large Pear tree from a distance. Catkins hang from the tree in spring and the cones are held upright and are egg shaped.

Where to grow Italian alder will do well on almost all types of soil however poor, it has become popular as an urban tree where it retains its leaves deep into the winter as a result possibly of street lights. (-20°/-15° C) Characteristics A large native tree which is common by riverbanks and damp places, it can grow to 25m (80ft) but is often coppiced and appears in a multistemmed form.

The leaves are large and almost round, catkins hang in clusters from about March onwards, and the cones when ripe hold large numbers of small seeds.

Where to grow One of the few trees that can cope with waterlogged ground it possesses nitrogen fixing nodules on its roots which enable it to colonise effectively.

(-20°/-15°C)

AESCULUS CARNEA BRIOTII

Characteristics The red flowered chestnut is a fairly common site in May with its bright red flowers held by the tree as though they were candles.

It does not grow to the massive scale of its white flowered relative with a maximum height of 15m (50ft). It has a generally round headed form with characteristic hand shaped leaves with five to seven fingers, the leaves are a rather dull green. It also produces fruit in the form of ‘conkers’ but not so profusely and with smooth shells.

Where to grow This is an easy tree to grow which will cope with most locations. Happiest in well drained loamy soils it will establish in all but very wet or waterlogged soils.

(-25°/-15° C)

AESCULUS HIPPOCASTANUM

Characteristics The Horse Chestnut is one of the most recognisable trees that grow in the UK. It can often grow to 30m (100ft) with a rounded wide spreading head and trunks up to 5m (15ft) or more across.

The characteristic very large leaves with five to seven fingers and the sticky winter buds are all well known as are masses of white candle like flowers that are present in early May. The fruit held in spiny cases are lustrous brown nuts up to 4cm (1½ inch) across and are a fascination to children of all ages. It is naturalised in the UK and must be present in almost every park in the country.

Where to grow An easy tree to grow, it will cope with most conditions except very wet or waterlogged soils. Happy in the country or city, it often self-seeds even in the most unlikely places.

ALBIZIA JULIBRISSIN 25/30

Characteristics Landscape value: A very adaptable and tough small tree providing a display of delicate pink 'pompon' flower heads in summer set against fine, feathery foliage. Of use in small to medium gardens as well as parks, gardens as a feature or to provide filtered shade.

Height: 5 metre(s) Width: 4 metre(s) Growth rate: Moderate.

Habit: Broad 'vase' shaped, spreading, with a flat crown.

Foliage: Rich green, feathery, bipinnate leaves (similar to many wattle species) that fold up at night. The leaves are subdivided into 10 to 25 pinnae, each with 40 to 60 leaflets (pinnules). Rustic brown in autumn.

Flowers: Heads of many small flowers with long showy pink stamens in summer. From a distance the flowers appear to be floating along the top of the branches. Flowers less abundant in cooler climates. Fruit:Long greyishbrown legumes in autumn follow flwering and are held into autumn.

Bark: Greyish-brown.

Where to grow Tolerances: Moderate drought, varied soil pH, moderately saline soils, strong wind and temperate to sub-tropical conditions. Best grown in full sun.

Potentially a weedy species in some areas. Generally seedling grown, so can have some variation in vigour and habit. (-15°/-10°C)

BETULA ALBA Albero deciduo, alt. 30m, diam. chioma 6 m. Foglie piccole verde chiaro, che diventano gialle in autunno. Fioritura Aprile Maggio. I tronchi principali hanno portamento eretto mentre i rametti più giovani tendono a ricadere.

Valore pH del terreno: 5 – 6 Molto rustico ( -30°C). Adatto ai climi di montagna.

Impiego: isolato, in gruppi o allineamenti. Resiste all'inquinamento atmosferico e alla salsedine.

Characteristics This large graceful native tree is featured in Coleridge’s poem thus “I pass forth into light – I find myself Beneath a weeping birch (most beautiful Of forest trees, the Lady of the Woods)”.

It is fast growing and can reach 20m (65ft) or more on maturity. The branches are notable by the fact that the ends are pendulous. The bark is white often with black diamond shaped markings. If you are looking for the smooth gleaming white bark, a better option is Betula utilis jaquemontii. The leaves of Betula pendula are relatively small, 3-6cm, and turn yellow in autumn.

Where to Grow It grows well on all types of soil even surviving in poor dry soils. It can withstand air pollution and thrives in cities. As a “pioneer” species it quickly colonises recently felled or cleared ground. Birch would have been one of the first trees to naturalise here after the last ice age. (-30°c)

BETULA UTILIS JACQUEMONTII Albero deciduo, alt. 10-15 m, diam. chioma 6m.

Portamento sferico. Foglie color verde scuro che diventano gialle in autunno.

Characteristics Himalayan Birch is easily recognisable by its dazzlingly white, silky smooth, shining bark.

As with other birches, as it grows, the old bark peels away revealing the new bark underneath. The branches are ascending and the ends do not droop in the way that the native Silver Birch does. The leaves are larger than Betula pendula and turn yellow in the autumn. It can reach height of 15m (50ft) and the pyramidal shaped head is approximately 8m (25ft) wide. The vivid trunks make this an ideal candidate to be planted in groups of three or as a multi stemmed specimen.

Where to Grow It is generally tolerant of most soils but prefers full light and good drainage.

(-25°/-15°C)

CARPINUS BETULUS Albero deciduo alt. 15 - 20m, diam. chioma 8 - 10m. Portamento sferico.

Carpinus Betulus

ALBERETTO

Characteristics Hornbeam a native large tree though probably only truly native in the South and East of England as one of the last of the species to arrive from continental Europe. A tree with a maximum height of 25m (80ft) though often less, it is upright when young but eventually forms a rounded elongated head. The leaves are oval and similar in size and form to Beech though with more prominent veins and rougher to the touch.

Where to grow Hornbeam will grow well in full sun or shade. It will quite happily cope with damp or wet soils, and even with a certain amount of temporary waterlogging, making it a suitable alternative to Beech in such situations.

It stands up well to hard pruning, has dense foliage and has been used more for hedges and topiary than as a woodland tree. (-30째/-20째C)

Carpinus Betulus

CESPUGLIO

CARPINUS BETULUS FASTIGIATA/PYRAMIDALIS Characteristics This is one of the upright clones of Pyramid Hornbeam which is very regular and upright when young but becomes more rounded with age. It can reach 15m (50ft) and is always densely branched Where to grow Pyramid Hornbeam will grow well in full sun or shade. It will quite happily cope with damp or moist soils and even a certain amount of temporary waterlogging. It’s neat shape and upright form lend it to be used for formal avenues and topiary. (-30°/-20°C) Carpinus Betulus Fastigiata ALBERETTO Carpinus Betulus Fastigiata CESPUGLIO

Catalpa Bungei

Catalpa Bignonioides

The Indian Bean Tree does not come from India and does not grow beans! It originates from the Eastern United states and was introduced in 1726. It has large heart shaped velvety leaves, very large when the tree is young. The leaves are late to emerge not appearing until late June and will be killed off by the first frost without changing colour.

The tree comes into flower in the middle of July with white flowers that have yellow and purple flecks. The flowers are produced in large clusters and can be so numerous as to obscure the leaves of the tree altogether, thus ensuring its status as one of the most appealing summer trees.

The beans are the tree's bean-like pods, which are very slim and almost perfectly cylindrical and can grow up to 16 inches in length. These pods contain winged seeds and remain on the tree throughout the winter before splitting and releasing the seeds.

It will grow to 15m (50ft) in good conditions with a wide spreading much branched head and is a popular parkland tree. It is not particularly long lived though there is a specimen in a Reading Churchyard that is 150 years old.

Where to grow To grow well it needs full sun and a fertile well drained soil, it will do better with a little bit of shelter from winds which can damage the large leaves. As it never forms a terminal bud the last bit of late summer stem growth is almost always damaged by winter frosts, which leads to its multi-branched habit.

(-30°/-20°C)

CELTIS AUSTRALIS Pianta decidua Alt. 20 - 25m, diam. chioma 8 10m. Portamento sferico. A crescita abbastanza rapida. Foglie decidue, ovali - lanceolate, di colore verde scuro, ruvide al tatto. Abbastanza rustica (-20째 / -15째C). Adatta ai climi di montagna. ed a qualsiasi terreno fertile e ben drenato.

Predilige quelli sassosi, aridi, anche calcarei, ma non troppo umidi. Impiego: viali, alberature stradali. Resiste all'inquinamento.

Characteristics An attractive and adaptable shade tree with a pleasant habit, Celtis australis is a species that often survives where others have failed. Very useful for street or avenue plantings or as a park tree.

Height: 11 metre(s) Width:10 metre(s) Growth rate: Moderate.

Habit: pyramidal when young, becoming broadly ovate with ascending and arching branches. The young stems display a slight 'zig-zag' tendency.

Foliage elliptic leaves up to 15 cm long with coarsely serrated margins.

Light to mid-green changing to soft yellow then yellowish-green in autumn.

Flowers inconspicuous. Male and female flowers are often separate on the same plant.

Fruit rounded drupes up to 1.25 cm in diameter on a long stalk. Bark grey and smooth, gradually forming narrow, corky ridges. Ornamental.

Where to grow Urban tolerant. Best in good rich, moist soil in a position receiving full sun but is adaptable to a wide range of site conditions, including compaction, partly wet or dry sites and acid or alkaline soils. Also tolerates air pollution, moderate wind and part shade.

(-20째/-15째c)

CERCIS SILIQUASTRUM

Characteristics The Judas tree can grow to a height of 12m (40ft) and reach 10m (35ft) in diameter, though more often forming a low and irregular 1-sided dome of bushy habit about 8m (25ft) tall.

The leaves are rounded and heart shaped, the bright pink-purple, pea like flowers are produced at the joints of the old wood in May before the leaves emerge. The seed pods can hang on the tree all winter.

Where to grow Defiantly a sun loving tree, to do well, it needs a warm sheltered sunny spot. It is perfectly hardy but a cold spring delays both flowering and leaf emergence. A member of the Pea family (Leguminosae) it needs a fertile free draining sandy loam and will not tolerate waterlogging.

(-20°/-15°C)

E' utilizzato come pianta ornamentale nei giardini e per le alberature stradali, grazie alla sua resistenza all'atmosfera cittadina; si presenta come un piccolo albero alto fino a 10 metri e più spesso come arbusto. Cresce molto lentamente.

Corteccia di colore grigio nerastro. Foglie colore verde carico e aspetto liscio e lucido; la pagina inferiore è glauca, in autunno assumono un bel colore giallo e cadono a novembre inoltrato. I fiori di colore rosa - lilla sono riuniti in racemi che compaiono prima delle foglie, in marzo – aprile, spuntano direttamente dalla corteccia dei rami e del tronco. Inizia a fiorire verso i sei anni di età. Europa meridionale, Italia, Asia, bassa quota, alt. massima 500m circa. Questa pianta preferisce i terreni calcarei e sassosi, senza ristagno idrico ma tollera anche quelli moderatamente acidi. Abbastanza resistente al freddo. (-20°/-15°C)

CHAMAEROPS EXCELSA Chamaerops excelsa di solito è classificata come Trachycarpus fortunei in quanto, quando fu introdotta in Europa dal Giappone, fu identificata come tale. E’ una pianta che si presta per essere coltivata sia in vaso sia in piena terra raggiungendo in questo caso anche i 3,5 m di altezza mentre in vaso rimane di dimensioni molto più contenute non superando i 2 m di altezza. Le foglie, portate da lunghi piccioli, si formano nella parte alta del fusto, sono a ventaglio con le punte che con il tempo diventano pendenti. I fiori sono riuniti in infiorescenze a pannocchia, di colore giallo mentre i frutti sono delle bacche scure.

Sono piante dioiche vale a dire che ci sono “piante femminili” e “maschili” cioè piante che portano solo fiori maschili e piante che portano solo fiori femminili. Esistono diverse varietà tra le quali una nana di dimensioni molto contenute.

Richiedono posizioni soleggiate, o leggermente ombreggiate; Possono essere allevate sia in vaso che all’aperto dove gli inverni sono miti con minime invernali intorno ai -15°C . Sono resistenti ai venti salmastri.

The hardiest palm tree in the world has identity crisis. This, on the other hand, does not stop us from trying this exotic beauty in our climate. Originally from the Himalayas, it is used to long periods of frost, and sometimes snow. It likes clay soil but the constitution must be permeable. If the soil is too heavy, it will need good drainage – this palm can easily rot from excessive water in the winter rather than extreme frost. Our hardiness is rated to -20°C but as every hardy palm this one, too, is sensitive for water in the top of the trunk where new leaves are borne. Therefore it needs to be covered before late autumn rains after which frost can come. First, carefully bind the leaves together. Then we suggest using a simple wooden construction / frame with a translucent but not transparent waterproof material, we use Kortexin. This will work as an umbrella for the head of the palm. It is necessary to leave the bottom free so it can breathe all winter. Only when temperature drops below -20°C overwrap the palm head tightly for max. 5 days to help it overcome the coldest winter days. Winter protection is left on the palm until early spring when there is no more danger of drenching the leaf heart and subsequent freezing. Dry spring frosts and late ground frosts of -3° to -5°C cause no damage. In temperatures below -15°C the leaves can be damaged or completely burnt, but the palm will make new ones in the spring, so there is no need to worry.

CRATAEGUS MONOGYNA Pianta a foglia caduca, Alt. 6m, diam. chioma 2.5m. Portamento fastigiato. Le foglie alterne, di forma ovoidale, con 3-5-7 lobi, lucide, di color verde scuro, misurano fino a 5-6 cm, foglia color arancio o rosso bruno in autunno. Fiore bianco, dal profumo intenso, seguito da bacche rosse. Adatta a qualsiasi terreno, anche calcareo. Non troppo arido. Valore pH del terreno: 6 - 7 Specie spinosa. Impiego: isolata, siepi difensive, macchie. Molto rustica (meno di -30°C). Resiste alla siccità.

Characteristics There is no finer sight in May and June than the froth of heavy-scented single white hawthorn flowers overloading our hedgerows. The native white hawthorn forms the basis of much of Britain’s hedges either pruned back as a hedging shrub or as individual trees left to grow up within it.

Grown as a tree it is small, making only around 7m (23ft) with a densely spreading, irregular outline. Shiny red berries, darkening as they ripen, cover the tree from late summer into winter providing food for thrushes, blackbirds and their winter cousins fieldfares and redwings.

As a hedge we recommend two rows, 45cm (18”) apart with the plants arranged in a staggered pattern, 4 plants to the metre. The impenetrable thorns make it a good barrier and its rate of growth is fast, giving rise to one of its other common names ‘Quickthorn’. You can plant a hedge entirely of hawthorn or plant our ‘natural mixed hedge’ where hawthorn makes up the majority of the mixture that native species can then be added to.

Where to grow Hawthorn is easy to grow in all locations, tolerating windy and coastal locations, plant in full sun or partial shade in freely draining soil. (-30°)

CRATAEGUS LAEVIGATA PAUL'S SCARLET Characteristics Double red flowers in May sing out from the branches of this robust little tree which is otherwise indistinguishable from the white hawthorn until this burst of cheerful colour, announcing the arrival of summer. Paul’s Scarlet grows to 6m (20ft) with a generally rounded shape. Although the lobed leaves are only small they are densely packed, forming a good screen during spring and summer. Even in winter the framework of stout, interweaving branches still offers useful cover. Birds often nest among the thorns and eat the red autumn berries.

Where to grow Hawthorns extend the spring blossom season by flowering shortly after the cherries so would certainly add interest to larger planting schemes. Paul's Scarlet in particular provides an ornamental twist on an otherwise native tree with its eye-catching double red flowers and would therefore be good planted in or near a natural mixed hedge bordering the garden.

This tree tolerates exposed sites and grows in full sun or partial shade on a wide range of soil types, even on soils over chalk.

FAGUS SYLVATICA – SYLVATICA PURPUREA Characteristics Beech is one of the most impressive European trees. It is traditionally the forest tree of the temperate zone of western and central Europe. It represents the last stage in the natural succession of a forest. Solitary beech trees have a wide, dense crown and low branches which hang down. As a tree in avenues or forests, it develops a dead straight trunk with branches high above the ground. Trees more than 40m (130ft) tall or 30m (100ft) wide are not uncommon.

The leaves are oval, green and grow quickly from the ‘cigar’ shaped bud in the first week of May. As a consequence of the young tree's ability to hold onto its dead leaves in the winter, one of the most common uses of beech is for formal hedging.

Keeping the hedge cut below 3m (10ft) preserves this phenomenon and gives the hedge all year cover, green from May to November, orange– brown the rest of the year.

Where to grow Beech can be difficult to establish. Unlike most trees, it is only after bud burst that root growth, for that year, begins. The first roots to appear are very thin (with a diameter of less than 0.5 mm).

Later, after a wave of above ground growth, thicker roots grow in a steady fashion.

They also prefer humus rich, light or medium soils and will not tolerate waterlogged root zones for any length of time. However during the establishment phase their root systems must not be allowed to dry out and regular watering is needed. This balance is crucial to planting success.

Pianta a foglia caduca Alt. 25 - 30m, diam. chioma 10 - 15m. Specie tipica delle zone montane. Foglie di colore verde intenso, che diventano gialle o porpora in autunno.

In inverno il fogliame secco tende a rimanere sulla pianta (in assenza di venti forti). Molto rustica (meno di -30°C). Adatta ai climi di montagna. Impiego: isolata, alberature stradali.

FAGUS SYLVATICA PENDULA – SYLVATICA PENDULA PURPUREA Characteristics Weeping Beech is a cultivar of common beech with fairly large tent like structure with masses of leaves creating a solid tumbling green wall in the summer.

The growth habit is for the leader to start off vertically and then turn and droop down into the crown, by this method the trees can become quite large, up to 25m (80ft) and make a dramatic feature.

Fraxinus Westhof'Glorie

Fraxinus Excelsior

Characteristics Ash is one of Britain's most common native trees. Its distinctive black buds, pinnate leaves and greyish bark mark it out from Britain's other large trees. One of our most useful timber trees as it grows quickly in a wide range of soil conditions. It produces a white, flexible, low moisture content timber. Tool handles and firewood are two common uses of ash A very large tree it can grow to 35m (110ft) in favoured spots and is common in hedgerows and woodland. The flowers appear in early April well before the leaves which rarely appear before early May. The winged seeds are held in bunches of ‘Keys’ in great profusion most years and hence propagate profusely in likely habitats.

Where to grow Ash are very versatile trees and will grow in a wide range of environments. They do not mind dry soils, but will not cope with prolonged waterlogging.

Happiest with full sun, they will also grow well in partial shade and are good in exposed and windy sites.

This makes them suitable trees for urban as well as rural planting. (-30°C)

Resistente all'inquinamento, alla siccità , alla salsedine.(-20°C)

Characteristics A botanical oddity remote from all other trees and plants, it is a survivor from a botanical group Ginkgoales widespread in the Jurassic and it is now the only living representative.

Ultimately a large tree to 20m (65ft) with distinctive leaves similar to the Maidenhair fern (Adiantum) which gives the tree its common name.

During autumn the green leaves turn a bright yellow then fall quickly in anything from a single day to two weeks.

Young trees tend to be tall, slender and sparsely branched, with the crown of the tree becoming broader over time. They have developed a resistance to most pests and diseases, allowing it an incredibly long lifespan. One tree in the Shandong province of China is thought to be 3,000 years old.

Where to grow The Ginkgo will grow almost anywhere. It adapts well to the urban environment, tolerating pollution and confined soil spaces. They rarely suffer disease problems, even in urban conditions. An extreme example of the ginkgo's tenacity may be seen in Hiroshima, Japan, where six trees growing between 1 and 2 km from the 1945 atom bomb explosion were among the few living things in the area to survive the blast.

GLEDITSIA TRIACANTHOS SUNBURST - SKYLINE - INERMIS Characteristics A member of the pea family the Honey Locust is a tree which has delicate fern like leaves subdivided into leaflets. It grows with an open, spreading canopy and has attractive, fine, somewhat weeping foliage. It is late into leaf and does well only in dry warm summers which can make it struggle in cool wet English weather. This is primarily a foliage tree having no flowers to speak of. The parent is native to central North America and is spiny, ‘Sunburst’ is a decorative and very popular thornless selection of the Honey Locust with first yellow and later on light green leaves. The second flush around the beginning of July is also yellow. It is one of the prettiest yellow-leaved trees. Sunburst grows to a generally thornless, small to medium-sized tree to 8m (25ft).

Where to grow Gleditsias are adaptable trees that can cope with a wide range of ground conditions they however do not like permanently wet or waterlogged ground. (-30°c)

Characteristics Often mistaken for a Maple, the Sweet Gum has similarly-shaped five-lobed leaves. However, while the leaves on the maple are arranged in opposite pairs, those of the liquidambar appear alternately. It is mainly grown for the autumn colour, the leaves turning brilliant shades of purple, crimson, orange and yellow, making it a popular ornamental tree.

This tree is another early introduction from the Eastern States of America. It is often found in swampy regions. In these conditions it can grow as tall as 45m (150ft) but is often much shorter and rarely grows to half that height in Britain.

Worplesdon is a selected variety of Sweet Gum chosen for its reliability in producing fiery shades of red, orange and yellow in the autumn. It is fairly fast growing and has an even upright conical habit. Autumn colour is always a bit of a variable on all trees depending upon a number of factors.

Where to grow Liquidambar grows in moist fertile soils it prefers warm summers and a bit of protection to grow well. It is perfectly hardy in the UK, however when planted in windy spots the top branches can snap off. It is therefore best planted in a sheltered spot.

Resistente all'inquinamento.

Characteristics The Tulip Tree is a very large tree with some specimens reaching over 30m (100ft). It is easily identified from its leaves which have a saddle shape, with a noticeable square end where leaves are normally pointed. It is a fast growing and vigorous tree.

A member of the Magnolia family the tree only starts to flower when it is about 20 years old. The flowers, which are cup shaped and a greenish yellow, appear sporadically in June or July, except in very hot summers.

Where to grow Tulip trees are suitable for any good, deep, well drained soils in full sun. They prefer moist soil which does not dry out too readily. They are most suited to parkland settings or very large gardens.(-30°/-20°C)

MAGNOLIA GRANDIFLORA GALLISONIENSIS Pianta sempreverde Alt. 25 - 30m. Fogliame grande, coriaceo, verde lucente sulla pagina superiore e rugginoso opaco su quella inferiore. Fiore bianco crema, grande, profumato.

Predilige terreni acidi, moderatamente umidi, ben drenati, fertili e freschi, non calcarei. Valore pH del terreno: 5 – 6.

Resistente all'inquinamento e alla salsedine. Abbastanza rustica (-20° / -15°C). Impiego: isolata, alberature stradali.

Characteristics Galissoniere is a large evergreen tree that is rarely seen free standing, more often growing against a wall.

It has large glossy green leaves which have a mat brown rust coloured underside. The flowers appear rather erratically over a period from June to November are white, large, cup shaped and fragrant.

A native of the southern United States it can, in its native habitat, grow to 20m (65ft) however in the UK 10m (32ft) seems to be a maximum. It has been grown in this country since 1734, though many of the original plants were destroyed in the great frost of 1739-40. This had the effect of conferring a rarity value on the survivors which were thought of as being hardier.

Where to grow Magnolias need moist soils with a high organic matter content. They do not like drying out nor do they cope with waterlogged soils. It is often thought that Magnolias will not tolerate alkaline soils however many of the common varieties will do well except on chalky soils.

As the flowers are frost sensitive they are best kept out of frost pockets and windy exposed spots.

MORUS ALBA – ALBA PENDULA – A. FRUITLESS – A. PLATANIFOLIA Gelso comune. Albero espanso con foglie ovate, talvolta lobate, lucide, verde vivido, lunghe fino a 20 cm, viranti al giallo in autunno. A fine estate produce frutti bianchi, insipidi, che diventano rossi a maturazione.

Altezza da 8 a 10 Mt, adatto al clima continentale temperato -10°/-15° Epoca di fioritura da Maggio a Giugno. Epoca fruttificazione da Luglio a Settembre. Resistente al terreno calcareo e al terreno secco Resiste all'inquinamento atmosferico e alla salsedine .

Il Morus Alba Pendula è un'altra specie di morus alba, chiamato così per il suo portamento pendulo. Ha un importante valore ornamentale, sia in fase di fruttificazione che quando è defogliato, grazie ad una ramificazione molto bella, che forma interessanti geometrie. Oltre che a scopi ornamentali, il pendula è coltivato anche per il suo legno molto resistente.

Esiste anche la varietà M. A. Fruitless che non produce frutto quindi non sporca la superficie sottostante.

White mulberry and its Pendula variety is one of the top popular weeping trees. No wonder – apart from its beauty it offers tasty fruit. Moreover its small size makes it an ideal specimen tree even for small gardens. Its deciduous leaves are heart-shaped, toothed at margins, up to 15 cm long, deep green and glossy, changing to yellow in autumn. Mulberry belongs to the same family as fig tree and has some of its genes. This is why some of the foliage is transformed to deeply lobed just like those on fig trees.

The fruit ripens from midsummer. It is oval to oblong, 2-3 cm long, black and easy to pick when fully mature. (not seen on fruitless varieties) White mulberry is perfectly hardy in Europe and should be cultivated in sunny. Grow it in any well-drained soil, constant moisture will guarantee healthier foliage. Heavy clay and water-logged soil may result in root-rot and death of the plant. It makes weeping branches that are fast growing if you prune them hard. Any pruning is best done in late autumn or midwinter to prevent it from bleeding. Hardy to about -10°/-15°C (USDA zone 4)

OLEA EUROPEA Alberi, sempreverdi, alt 6-8 mt, fino a 20 mt. crescita lenta Si adatta a qualsiasi terreno, anche calcareo, sassoso o vulcanico, ben drenato, ma non terreni umidi e freschi Sole, mezz'ombra, posizione calda e protetta. Clima mite.

Resistente all'inquinamento, alla siccità, alla salsedine Fogliame piccolo, stretto, argenteo, coriaceo. Fiore piccolo bianco, non molto significativo, ma profumato a Giugno. Abbastanza rustica, ma poco resistente al freddo umido (-5° / -10°C). Impiego: isolata, pianta da frutto. Disponibile in diverse varietà.

Olea europaea subsp. Africana has a neat, wide-spreading, dense crown with glossy greygreen to green leathery leaves. The flowers are very small and somewhat inconspicuous but sweetly scented. The glossy black fruits are edible, the fruit from some trees being pleasantly sweet tasting, while fruit from other trees may be sour or bitter. It takes takes well to pruning, which should be commenced while the tree is still young. A very useful tree in drier areas of the country as the foliage is eagerly browsed by stock and wild game.

The root consists of a sturdy tap root with many lateral roots. The roots can be aggressive but this may be the exception as many sources state that the root system is not aggressive and the tree can be used in small gardens.

OSTRYA CARPINIFOLIA (Carpino Nero)

Characteristics

Albero originario dell' Europa Centrale - Asia Minore dal portamento largamente conico e arrotondato con foglie verde scuro, ovate e doppiamente dentate fino a 10cm. , fogliame di un bel giallo luminoso in autunno.

Altezza max da 15 A 20 Mt. a foglia caduca Si adatta ai climi freddi delle Alpi e del Nord Europa -15°/-25° Predilige un ambiente ben soleggiato, fiorisce da aprile a maggio, è resistente al terreno secco e povero.

Resiste all'inquinamento atmosferico e alla salsedine.

Viene impiegato come pianta ornamentale in parchi e giardini, oltre che per alberature di strade e viali cittadini.

Produce un legno pesante e compatto, di colore rosso-bruno, usato principalmente come combustibile.

European Hop Hornbeam is a close relative of the common Hornbeam and is native to southern Europe. It gets its common name from the seed clusters that hang down like bunches of hops.

A fairly quick growing tree which will reach 15m (50ft), upright when young then spreading to become very broad. Both the leaves and the long male catkins which appear in spring are similar to that of a member of the birch family with which it is easily confused. The distinct fruit clusters of nutlets hang almost 5cm (2 inches) long which give the tree its common name.

Where to grow This tree will grow in most situations, it prefers moist, humus rich, free draining soils but will happily cope with poor soils and exposed positions. (-15°/-25°C)

PARROTIA PERSICA

Characteristics Persian Ironwood originates from what used to be called Persia, now modern day Iran. As its name suggests, the wood it produces is almost indestructible. In its native habitat it can grow up to 12m (40ft) in height but in Britain it is often kept as a large bush. Even fully grown specimens retain something of a bush-like quality as they are often as wide as they are tall, and almost pyramidal in shape.

It is mainly planted for its autumn colour. As soon as the glossy green leaves begin to change colour a range of hues appear. Rich crimsons, brilliant yellows and warm ambers form a spectacular autumn sight.

Where to grow Parrotia persica prefers a rich, fertile soil that does not dry out. Grow in a well-drained or moist but well-drained soil in sun or partial shade it is well suited to an open woodland setting or a sheltered spot away from cold, drying winds. (-25°/-15° C) Pianta arbustiva originaria dell’Asia centrale, molto apprezzata sia per la resistenza alle basse temperature che la colorazione particolare che assume durante la stagione autunnale.

Generalmente raggiunge i sei metri di altezza, benché esistano degli esemplari che si innalzano fino ai 10 metri.

Le foglie sono ovali e leggermente dentate, con colorazioni che nella stagione autunnale raggiungono il meglio della bellezza, passando dal violaceo allo scarlatto, dal giallo all’arancio al rosso. I fiori sono poco significativi, fanno la propria comparsa nella stagione primaverile, per poi lasciare il posto ai frutti, costituiti da capsule ovali. La Parrotia persica riesce a resistere anche a temperature inferiori allo zero ed è per questo che può essere coltivata direttamente in piena terra.

(-25°/-15° C)

PLATANUS ACERIFOLIA – PLATANUS ORIENTALIS Characteristics London Plane - Platanus Acerifolia A very large tree often over 30m (100ft) tall a hybrid between Western or American Plane, Platanus orientalis and the Eastern or Oriental Plane, Platanus occidentalis. It is not known where this hybrid arose, probably in Spain or southern France in about 1650, it was first planted in London in 1680.

It has large maple like green leaves which appear in midMay. It is also distinguishable by the peeling bark, great plates of bark fall off revealing a camouflage pattern of browns, greys and yellows of the fresh wood beneath. This process ensures that pollutants are removed and the tree is kept healthy.

Where to grow As well as this self-cleaning process, this tree proves how well-suited it is to the urban world by being resistant to drought, amenable to regular pruning and unbothered by impacted soil.

Characteristics Oriental plane is native to Asia Minor and India, one of the parents of London Plane. It is a fast growing large tree growing to 25m. or more.

Oriental Planes have a wide spread sometimes on a relatively short branching bole and historically in Mediterranean regions been planted as shade trees.

They are important trees in Persian gardens, which are built with water to provide cool shade in the summer.

Where to grow An easy to grow tree it will grow well in most soil conditions however poor. As a large tree it needs a lot of space to develop fully, but can easily be pollarded to reduce its size and even be trained into shade panels by a form of horizontal pleaching.

Characteristics White poplar is a conspicuous tree with its very white woolly underside to its leaves which show when moved in a light breeze. It is also called ‘Abele’ which simply means white.

Like most poplars it is very fast growing and used as a boundary tree. It is also very salt tolerant and hence often planted in seaside locations. This large tree is well naturalised in the UK. It is not considered to be native although was introduced at an early unknown date. It will grow to 18m (55ft) Lombardy Poplar is a clone of the Black Poplar (Populus Nigra) It has a characteristic, narrow, pillarshaped crown and fastigiate habit. It grows very quickly and can reach 30m (100ft) with a width of 5m (16ft) or less.

It has roughly rounded, triangular to diamond-shaped leaves which like the twigs and buds are smooth and hairless.

Where to grow Poplars will grow easily almost anywhere, they have the advantage of growing very big, very fast. Like willows, poplars have very vigorous and invasive root systems. They will tolerate waterlogged and heavy ground but will also grow well in good deep loams.

They are not so good in very dry positions they will however manage salt air which makes them a useful seaside tree.

PRUNUS Characteristics PRUNUS AVIUM Wild Cherry is the ancestor of the cultivated cherries. It is native to large parts of Europe and West-Asia and naturally grows at the edges of mixed forests.

Conspicuous in spring with its white blossom of single cup shaped flowers, followed by shiny red berries in June and good autumn leaf colour make this one of our most beautiful indigenous trees.

A fast growing tree it can easily reach 10m (30ft) in 10 years ultimately reaching 25m (75ft) in ideal conditions. The greenish yellow-brown wood is very popular in the furniture industry and is also much used as veneer for music instruments and different tools.

Where to grow Wild cherry grow best in full sun on moist fertile deep loamy soils, it is perfectly happy on alkaline soils which it prefers. It will therefore grow well in most garden or parkland positions. Poor soils should have organic matter added to the backfill during planting. It does not like waterlogged or permanently wet ground. (-30°/-20°C)

Characteristics The holly or holm oak is an evergreen species that is native to the countries around the Mediterranean Sea. It has tough leathery evergreen leaves dark olive green on the upper side with a pale whitish underside. Often seen as a multi stemmed bush or hedge it can becomes an impressive tree of 20-25m(80ft) high with a trunk diameter of 2m (6ft) and more.

Where to grow Cultivated in the UK since at least 16th century it grows everywhere successfully except in the North of Scotland. It is more numerous particularly in the warmer south west where it has naturalised. It thrives near the sea being tolerant of salt laden air. (-15°/-20°C)

QUERCUS ROBUR – ROBUR FASTIGIATA Characteristics English Oak is an iconic tree, easily identified by almost everyone with its lobed leaves and acorns. It is long lived tree with a durable hard timber which was used for a multitude of uses including construction and at one time ship building as it is slow to rot even in extreme waterlogged conditions.

Often thought to be slow growing it is really quite quick on good soils being 20m (60ft) by 2m (6ft) in 50years. Some of the oldest trees are pollards and can be up to 800 years old.

Many famous named trees have large boles with circumferences up to 14m (45ft) and stag horned heads.

Native and widespread it grows up to nearly 500m (1,600ft) An important species for wildlife, more than 400 insect species have been recorded as being hosted by this species, these in turn support a wide range of birds and small mammals.

Where to grow English Oak will grow best on deep moist fertile loamy soils. It will however cope with almost any conditions. It compensates for the poor ground by growing more slowly and in truly awful exposed conditions resembles little more than a twisted large shrub. (-30°/-20°C) Quercus Robur Fastigiata Large columnar, deciduous tree maturing into a dense, elongated oval shap with a short trunk. Dark green lobed obovate leaves, pale bluish-green beneath. Autumn colour is yellow to tan, quite dull, often remaining on the tree for some time before dropping. Acorns elongated oval to about 2.5cm long. Adapted to a wide range of soil pH. Suitable for site where spread is limited, good avenue tree.

QUERCUS RUBRA – QUERCUS PALUSTRIS Quercus Rubra Red oak is a fast growing Oak from the East of North America. It is one of the fastest growing Oaks shoots growing up to 2m (6ft) a year in good conditions. It can reach 25m (80ft) in 150 years.

It was introduced in the early 18th century and is fairly common in parks and large gardens where it has naturalised in the south. In spring the leaves when first unfolded are a bright yellow for a couple of weeks in May, but become a matt green later. In the autumn the leaf colour changes uniformly over the crown to a strong red, hence the common name.

Where to grow Quercus rubra will grow best in moist but welldrained deep fertile soils. (-30°/-20°C) Quercus Rubra

Quercus Palustris Pin oak is a beautiful large tree you can see growing in moist or boggy places. It has beautiful leaves, deeply lobed. They are deciduous, glossy green in summer and orange, red and burgundy purple in autumn. Pin oak is one of the most attractively coloured trees in autumn in the wild.

Pin oak likes moist or even boggy locations if it grows there from a seed. Plants with a root ball need to be planted the way that they do not sit directly in water.

Later the root system can take long term flooding but it has to be well established first. Grow it in full sun, preferably in acid soil for best foliage colour. Newly planted trees need to be staked for 2-3 years to establish. Fully hardy to min. -30°C (USDA zone 4), perhaps a little more.

Quercus Palustris

Originaria delle zone centroorientali del Nordamerica.

Introdotta in Europa nella prima metà del Settecento a scopo ornamentale, a causa della sua vistosa colorazione rossa autunnale, si trova facilmente anche in Italia nei parchi e nei giardini. Raggiunge un altezza di circa 25 metri, quasi colonnare nei giovani esemplari per poi diventare globosa ed espansa. La scorza è inizialmente grigia e lucente, poi diventa opaca, rugosa e fessurata verticalmente.

Foglie caduche, alterne, possono essere lunghe fino a 20 cm, con picciolo lungo circa 2 cm. In autunno, prima di cadere, assumono una bellissima colorazione porpora.

Fiori maschili giallini, femmili, solitari o a piccoli gruppi, sono inseriti sui rami con un breve peduncolo.

Le ghiande ovali (2-3 cm) hanno cupole un po' appiattite sostenute da un breve peduncolo. Cresce bene in terreni non calcarei.

Black locust is a rapidly growing, deciduous tree that is native to North America. This member of the pea and bean family (Leguminosae) was first introduced to Europe from North America at the beginning of the 17th century. Its hanging clusters of scented, white flowers are a common sight in streets and parks in England in June and July. Black locust, especially in its many named cultivars, has become a much-loved ornamental in western European gardens. Its cultivars include pink-flowered and metallic, yellowish-green leafleted forms.

Despite its popularity as an ornamental, it can become invasive due to its prolific seed production, and it also spreads aggressively by suckering from the roots. (-30°/-20°C) Robinia Ps. Umbraculifera In cultivation since the early 1800s this top grafted clone forms a rounded and compact crown ideal for urban piazzas and town gardens.

It is more regularly seen in French and German cities than here in the UK. This small, mop-headed tree seldom flowers and requires very little maintenance.

The largest tree of this clone I have heard of is about 6 metres in diameter.

It is best to have them top grafted between 1.82 metres from ground level so they can easily be walked under.

It thrives on most soils and is tolerant of urban conditions. Mature height: 5-10m

Robinia Ps. Casque Rouge This delightful cultivar of False Acacia makes a particularly fine garden, verge or parkland tree as its profuse flowers emerge in June after the Cherries, Crab Apples and Thorns have all finished.

This tree of medium height and broadly rounded habit, it is greatly prized for its showy and highly ornamental lilac-pink flowers that are richly appreciated by all those who notice.

It thrives on any soil, and tolerates urban pollution, but is not good in windy, exposed locations due to its rather brittle branches.

Robinia Pseud. Frisia This superb yellow clone has been very popular over the passed 25 years and can now be seen in most urban areas in the UK. It is tolerant of dry conditions and is well suited to cope with reflected heat and light from buildings and pavements. It won the Award of Garden Merit in 2002.

Raised in the Netherlands in the mid 1930s, this medium tree of rounded habit only rarely flowers, but displays its beautiful golden yellow foliage from spring through to autumn. It thrives on any soil, and tolerates urban pollution.

Mature height: 10-15m

SALIX ALBA – SALIX BABILONICA Salix Alba White willow is a native large tree which grows in a wide billowing shape to 25m (80ft) and is common all over the UK usually in lowland river valleys. It has characteristic long narrow leaves with a white downy underside which become visible in a breeze making the whole tree shimmer white. Like willows generally white willow grows quickly, can be coppiced to produce a multitude of stems, which can be used in weaving hurdles etc. Where to grow: All willows are extremely adaptable trees they will grow in most conditions including very poor permanently waterlogged soils. They will also do very well in good conditions and will tolerate a certain amount of maritime exposure. They do however require a sunny spot.(-30°/-20°C) Salix Babilonica A moisture loving shade tree with long pendulous branches that sweep to the ground and sway in the breeze. The weeping willow is a fast growing, graceful tree for large parks and properties.

Pendula varietà piangente, reperibile come innesto ricadente su un tronco ad habitus eretto della sofora comune. Essendo più bassa della sofora classica (di rado arriva a 10 metri) può essere utilizzata in contesti meno spaziosi. I rami sono arcuati, pendenti e contorti, molto coreografici in inverno, e le foglie ricadono verso terra creando una cortina verde davvero notevole per la sua bellezza. Regent varietà di successo, selezionata per la sua crescita più rapida e la fioritura precoce (a 5 anni invece che 10 o più).

Japanese pagoda tree is a beautiful large tree with exotic looking leaves and flowering in August. It bears deciduous, pinnate, rich green leaves similar to locust leaves but individual leaflets are more elliptic and longer. They change to yellow in autumn and fall down quickly. The whole leaf is up to 25 cm long and slightly pendent but in a relaxed, not weeping way. Individual flowers are small, creamy yellow and are compound in huge, 25-35 cm long panicles. They come out from early August and last for about 3 weeks.

Weeping Japanese Pagoda Tree is a picturesque weeping tree with stiff drooping branches. It is formed by grafting the pendulous variant onto stems of the ordinary form at about 3m (10ft). This forms a natural arbour. The leaves are pinnate, very similar to an Ash leaf, but don’t unfurl until late May. It will flower in hot summers, but not until the tree is mature.

Regent is a variety that should flower as a young tree, perhaps from 5 years of age. The tree grows fast when young, forming an oval crown first, and once it starts flowering the growth rate slows down and the crown is getting more rounded. Pruning is possibly in early spring but radical pruning may cause loss of flowers for one season. Irrespective of its large size in maturity the crown is airy and does not cast a deep shade. It adapts to any type of soil except for marshy, and withstands air pollution. When fully established it tolerates drought. Avoid transplanting in autumn. Plants with well-ripened are very hardy to min. -29°C (USDA zone 5).

TAMARIX GALLICA – TAMARIX PARVIFLORA / TETRANDRA Tamarisk is a beautiful plant with tiny leaves and profusion of flowers in summer. The flowers are small, pink, composed in long racemes. Deciduous leaves are scalelike, mid green, very small. Overall appearance is feathery and very fluffy and the plant looks great in a Mediterraneanstyle landscape, or combined with other larger plants with leathery foliage.

It grows medium fast and looks best when pruned annually.

Cut back 80% of previous year's growth in early spring to encourage new growth with plentiful of flowers on a dense and compact shrub.

Grow tamarisk in full sun, dry or medium moist soil. It does not need a specific pH or too fertile soil. However, if you prune it hard a portion of a slow-release fertilizer is recommended. Very hardy to about -30°C (USDA zone 2).

Tamarix Gallica Dark brown branches support vivid green foliage and pink fluffy flowers in summer that are borne from new season’s wood.
