ANGIOSPERMS
(Greek; Angion, a vessel or a container; Spermos, seeds) The name means covered seed, referring to the fact that the seeds from these plants are formed inside containers called fruits. Angiosperms are the largest group of plants in the plant kingdom. They are known as the 'flowering' plants and consist of 250,000 species (88% of all plant species). The reproductive structures are - stamen and carpel present inside a flower. Pollination occurs by insects, birds, wind, water. The seeds of angiosperms contain either one or two cotyledons-a seed leaf; a food-storage structure. Because of this characteristic, angiosperms are subdivided into two major groups-the dicots (di-, "two"), and the monocots (mono-, "one"). Deciduous trees are angiosperms. Angiosperms usually have broad leaves that change color and die in the autumn. Angiosperms are sometimes referred to as “hardwood�.

NOTES: State tree of Ohio. Indians named the fruit of the buckeye tree 'hetuck', mean-
ing the eye of a buck, which it resembles. The Indians powdered the seeds and dumped them into small pools. This would stun the fish and make them rise to the surface, where the Indians quickly collected them. It is also reported that a flour made from the seeds makes an excellent library paste which will repel roaches. Buckeye wood is now used extensively for making artificial limbs because it is light, easily worked, and resists splitting, it is of 10 little commercial importance. Its main modern use is for pulp.

DISEASES / leaf blotch; Bleeding Canker: half of all Horse-chestnuts in Great Britain are now INSECTS: showing symptoms to some degree of this potentially lethal bacterial infection NOTES: Native to Europe. Seeds have been reported to be poisonous; deer are able to safely
digest. Seeds are called 'conkers'. Apparently name is derived from the observation that eating them cured horses of chest complaints. Seeds contain a soapy juice (alkaloid saponins) and were used in France and Switzerland for whitening hemp, flax, silk and wool: nuts dried, ground, added to soft water (rain or river), stirred well; water becomes frothy, turns milky white. Used in Bach flower remedies: when the buds are used it is referred to as "Chestnut Bud", and when the flowers are used it is referred to as "White Chestnut".

NOTES: Is the last tree to grow leaves in the spring. The leaves generally do not color in autumn before
falling, instead, they either fall abruptly after the first hard freeze, or turn a slightly yellowbrown before dropping off. Wood: quite soft, does not rot easily, and has the lowest shrinkage/ expansion rate of any domestic (USA) hardwood. Used for furniture, interior trim and cabinetry; occasionally as a tonewood in guitars. Excellent for carving and boatbuilding. Name is derived from the Catawba Native American name "catawba" for these trees as their tribal totem, with the spelling Catalpa being due to a transcription error on the part of the describing botanist (Scopoli) making the first formal scientific description of the genus. AKA: Hardy Catalpa, Western Catalpa, Cigar Tree, Indian bean tree, Indian cigar and Catawba-Tree.

DISEASES / leaf spot, powdery mildew, scale, nipple gall (disfigures leaves) and witches' INSECTS: brooms are common, though minor problems NOTES: Extremely adaptable, but tree can be injured by Dicamba herbicide used over its root
zone. Longevity: 150 to 200 years. Medicinally, the bark was decocted to serve as a gynecological aid that could induce abortion, regulate menstrual cycles, and treat venereal diseases. Bark decoctions were also taken for sore throats. Hackberry: The "hack" apparently is a corruption of the Scottish "hag" (witch), however the "Hagberry" in Britain is the name given to sour bird cherries. The application of that name to Celtis occidentalis was possibly a result of the early colonists confusion with regard to the small cherry-like appearance of its fruit (Peattie, 1953, 1966).

USE / VALUE: attracts wildlife; shade-tolerant; best used in rich natural areas due to its relatively narrow range of adaptability; naturalized areas, large open spaces, lawn tree, parks, golf courses
DISEASES / Beech Bark disease becoming major killer of Beeches in NE U.S. Beech blight INSECTS: aphids
NOTES: AKA: Beechnut. Because its wood is heavy, hard, tough and strong: until the advent of the
modern chainsaw, during lumbering beech trees were often left uncut to grow. As a result, many areas today still have extensive groves of old beeches that would not otherwise occur. Today, the wood is harvested for uses such as flooring, containers, furniture, handles and woodenware. Beech nuts were one of the primary foods of the now-extinct passenger pigeon, and the clearing of beech and oak forests are pointed to as one of the major factors that may have contributed to the bird's extinction. Fagus: Latin. from Greek "phagein" (to eat - edible nuts), grandifolia: Latin grandis, large, and folium, leaf.

NOTES: AKA: Red Ash — At one time Fraxinus pennsylvanica was known as the Red Ash and
F. p. var. laceolata was called the Green Ash. In his Manual of the Trees of North America (1949), C. S. Sargent points out that in the east the glabrous leaves and glabrous branchlets of the Green Ash “appear distinct from the Red Ash”. But more westward there is a slight pubescence on the leaves and branchlets, making it impossible to distinguish between the two. He states that the fall color of Red Ash foliage is “yellow or rusty brown”, others call it yellowish-brown. Most authorities now lump these two types of ash into a single species, Fraxinus pennsylvanica, with a the common name of Green Ash (Dirr, 1998). pennsylvanica, meaning from Pennsylvania

AKA: Kew-tree, Maidenhair-tree: refers to the similarity of leaves tothose of the maidenhair fern. the tree currently occurs in the wild only in the northwest of Zhejiang province in the Tianmu Shan mountain reserve in eastern China. Engelbert Kaempfer, the first Westerner to see the species in 1690. Considered a living fossil; geologic records indicate that ginkgos have grown on Earth for 150 million years. Old individuals are also capable of producing aerial roots (chi chi) on the undersides of large branches in response to disturbances such as crown damage; these roots can lead to successful clonal reproduction upon contacting the soil. The roasted seeds are used for food by the Chinese, but the fleshy layer can cause dermatitis/blistering. Ginkgo: from the Chinese yin-kuo, silver apricot. biloba: two lobed, leaves sometimes incised or divided.

DISEASES / canker, brittle wood, Willow Anthracnose INSECTS: NOTES: Numerous (350-400) Willow species and related hybrids of weeping habit are all similar in cul-
ture, ornamental value and landscape use. Early Chinese cultivar selections include the original Weeping Willow Salix babylonica 'Pendula', in which the branches and twigs are strongly pendulous. However, most Weeping Willows outside China are hybrids between this cultivar, and either White Willow Salix alba (Salix Sepulcralis Group) or Crack Willow Salix fragilis (Salix Ă&#x2014; pendulina Wenderoth), which are better adapted to the more humid climates of most heavily populated regions of Europe and North America. The most widely grown Weeping Willow cultivar is Salix Sepulcralis Group 'Chrysocoma', with bright yellowish shoots. The active extract of the bark, called salicin, after the Latin name Salix, was isolated to its crystalline form in 1828 by Henri Leroux, a French pharmacist, and Raffaele Piria, an Italian chemist, who then succeeded in separating out the acid in its pure state. Salicylic acid, like aspirin, is a chemical derivative of salicin. Used for basketry, furniture. Salix: Latin, willow, also from the Celtic sel, near, and lis, water; alba: white babylonica derives from a misunderstanding by Linnaeus that it was the tree described in the Bible in Psalm 137, "By the rivers of Babylon, ... hung our harps upon the willows in the midst thereof ..."

GYMNOSPERMS
(Greek; Gymnos, no covering, naked; Spermos, seeds) In evolution, gymnosperms are more primitive than angiosperms. There are between 700 900 currently living species of Gymnosperms. The leaves are usually needle-like and stay green year round. They differ from angiosperms because they adapted to climate conditions. Needle-like leaves conserve water by slowing down evaporation, a very successful adaptation in temperate and cold climates. Often covered by resins for protection from predators, fire, etc. Gymnosperms are non-flowering plants that produce seeds in the open spaces of cones. Their seeds are 'naked' meaning they are not enclosed by the ovary and flower. In Gymnosperms, the reproductive structures are megasporangium and microsporangium. Gymnosperms rely on the airborne transport of their pollen, and most produce huge amounts of pollen. Evergreens are gymnosperms. There are four classes of Gymnosperms: conifers, cycads, ginkgo, and gnetophytes. They make up the oldest living tress, the most massive trees, and the tallest living trees. The Bristle Cone Pine, some of which are over 4,000 years old, are the oldest living plants. The Sequoia and Bal Cypress are the most massive of living plants. The Giant Redwood, which can reach over 300 feet tall, are the tallest plants known. Gymnosperms are sometimes referred to as â&#x20AC;&#x153;softwoodsâ&#x20AC;?.

DISEASES / Armillaria shoestring root rot, Pine needle rust, needlecasts, Scleroderris canker, INSECTS: Sirococcus shoot blight, Sphaeropsis shoot blight and canker NOTES: Native to North America. State tree of Minnesota. Sometimes called "Norway" Pine for the
homeland of the men who logged it. Longevity: 400-500 years. Red Pine is self pruning; there tend not to be dead branches on the trees, and older trees may have very long lengths of branchless trunk below the canopy. Wood used for lumber, piling, poles, cabin logs, railroad ties, posts, mine timbers, pulpwood, and fuelwood. Red pine is known to have little genetic variation and is one of the most homogeneous pine species studied (Fowler and Lester 1970). Therefore, when a pest outbreak on red pine does occur, there is often little resistance to the attack. Attempts to introduce genetic variability into red pine by crossing it with other pines have led to the conclusion that strong genetic barriers, biochemical barriers, or both exist in red pine (Burchert 1979). pinus: Latin from Greek. pitus, pine; resinosa, Latin, very resinous

Berries make wonderful pies and jams. An alternative name for serviceberry, shadbush, derives from folklore correlating the flowering of the species with the running of shad in rivers. Native Americans used Saskatoon serviceberry wood to make arrow shafts, spears, and digging sticks. They made a tea, used for treating colds, by boiling the branches. Many Amelanchier cultivars, are derived from A. x grandiflora and A. laevis (Dirr (1998). Amelanchier: the French name for A. ovalis. Serviceberry: "It is from the fruits that the Sarrvissberry takes its name, for the word is a transformation of the sorbus given by the Romans to a related kind of fruit. Sarviss is a good Shakespearean English form of the most classic Latin, whereas Serviceberry is meaningless as a name, or is at least a genteel corruption of an older and more scholarly form."

B. davidii, grows like a weed; first introduced into Great Britain in the 1890's, and by the middle of the 20th century it had thoroughly naturalized the wastelands of southern England. A single flower cluster of 'Potter's Purple' was found to produce over 40,000 seeds. Now B. davidii is listed among the top 20 invasive weeds in England; also in New Zealand and Australia; classified as a noxious weed in Oregon and Washington.
Buddleja: after the Rev. Adam Buddle (1660-1715), an amateur English botanist and vicar of Farmbridge in Essex. Linnaeus spelled the genus as Buddleja, in his Species Plantarum, published in 1753, in which the genus was first described. davidii: after French missionary and naturalist Father Armand David, who discovered the species in 1869.

Discovered in 1863 in a hedgerow in England. Being a grafted
shrub, Harry Lauder's walking stick does require some special care. The rootstock is either Corylus colurna or often the American filbert, C. americana. There is a tendency for suckers to shoot up from the rootstock. You must prune off these suckers so that the plant does not revert to the characteristics of its rootstock. Corylus: from korylos, the Greek name of the plant; avellana: of Avella Vecchia, Italy. Common name refers to Sir Harry Lauder (1870-1950), a Scottish entertainer who sported a trademark crooked walking stick.

Bell. One of the first shrubs to bloom in spring. More cold hardy Forsythia* (USDA Zone 3-4) have been developed from F. ovata, often crossed with F. europea. **Flower's production of Lactose is impressive and is very rarely established in other natural sources except milk. Forsythia intermedia is a hybrid between F suspensa and F. viridissima. Many cultivars have been selected from this cross including dwarf and compact forms. Two are commonly cultivated for ornament: Forsythia Ă&#x2014; intermedia is the more commonly grown, is smaller, has an upright habit, and produces strongly coloured flowers. Forsythia suspensa is a large to very large shrub, can be grown as a weeping shrub on banks, and has paler flowers. F. suspensa is considered one of the 50 fundamental herbs in Chinese herbology. Forsythia: after William Forsyth (1737-1804), Scottish gardener and writer, director of the Chelsea Physic Garden in 1770, maker of the first rock garden in the UK and one of the founders of the Royal Horticultural Society; he became the superintendent of Royal Gardens, Kensington, Palace.

Native to eastern and central US. American hazelnut (Corylus americana) has similar shaped leaves, but the teeth are smaller and more sharply pointed. Native Americans considered witchhazel an important medicinal plant: bark used to treat skin ulcers, sores, and tumors; boiled or steaming twigs to loosen and soothe sore muscles. Witchhazel tea was taken to stop internal bleeding and to treat dysentery, colds, and coughs. The modern witchhazel industry is centered in Connecticut, where the branches are harvested from the wild by cutting them off at ground level in the fall. The bushes resprout, cut again a few years later. The distilled oil, (one of the few herbal products approved by the U.S. FDA as an ingredient in nonprescription drugs), goes into extracts, lotions, and salves for pain relief, skin care, and hemorrhoid treatment. Hamamelis: from the Greek for pear-shaped fruit

DISEASES / few disease or pest problems, but Winter leaf and stem burn; heat stress in INSECTS: hot, dry summers NOTES: Hardiest of the hollies. AKA: Meserve Hybrid Holly, Blue Holly. Plant one male plant for every three to five female plants, to ensure good pollination and fruit set on the female (berry-laden) plants. Use 'named pairs' as mismatch of blossom times by even one week will result in poor to non-existent pollination and little or no fruit set on female plants; if a male counterpart in a named pair is not available, use 'Blue Stallion' as the male pollinator. Ilex: from a similarity to the leaves of the evergreen oak native to the Meditteranean, Quercus ilex. Kathleen K. Meserve of St. James, New York, made crosses between the hardy species, I. rugosa, native to northern Japan, and I. aquifolium, the English Holly, which resulted in a series of plant introductions called "Blue Hollies"; many selection names beginning with "blue".

AKA: Silkworm Mulberry, Russian Mulberry. Known as Tuta in Sanskrit; An etiological Babylonian story that was later incorporated into Greek and Roman mythology attributes the reddish purple color of the white mulberry (Morus alba) fruits to the tragic deaths of two forbidden lovers, Pyramus and Thisbe. The white mulberry is widely cultivated to feed the silkworms employed in the commercial production of silk. It is also notable for the rapid release of its pollen, which is launched at over half the speed of sound, making it the fastest known movement in the plant kingdom. Fruits are eaten, often dried or made into wine. In traditional Chinese medicine, the fruit is used to treat prematurely grey hair, to "tonify" the blood, and treat constipation and diabetes. The bark is used to treat cough, wheezing, edema, and to promote urination. It is also used to treat fever, headache, red dry and sore eyes, as well as cough. alba: white

SEE REFERENCE SECTION FOR LIST. Over 10,000 different hybrid cultivars have been registered or named in the International Register, of which only 2,000 are generally available. Lights Azalea Hybrids Series: deciduous shrubs developed at the University of Minnesota Landscape Arboretum; they can withstand very cold temperatures (- 35°F to - 45°F) without significant damage. Northern Lights are F1 hybrid seedlings, the first in the series introduced in 1978. 'PJM' hybrids: named after Peter J. Mezitt, founder of Weston Nurseries, Massachusetts; evergreen hybrids resulting from a cross between R. carolinianum and R. dauricum var. sempervirens. Azalea plants are very toxic to equines, sheep and goats, but cause no problems in cats or dogs. All parts are poisonous, including the nectar, causing mouth burning, followed later by many sympoms including coma and convulsions. Azalea is also the flower of the astrological sign Sagittarius. Azaleas, from Greek, azaleos, meaning dry.

Siberian Cypress Microbiota decussata
Microbiota can be a little tricky to distinguish from low-growing junipers as their leaves look quite similar. In fact, the main differences are that they have fewer pointy, awl-shaped leaves/needles as illustrated in the photo at left (a juniper branchlet is at left, microbiota is at right). In addition, the branchlets of microbiota tend to be more flattened than those of juniper. Also, grabbing a handful of microbiota foliage won't hurt as their needles are soft and flexible.

Roses
Family: Rosaceae
Genus: Rosa
The name ‘rose’ comes from Latin ‘rosa’ which derives from the ancient Greek ‘rhoden’ meaning ‘red’. In general, roses are placed in one of three main categories: Wild, Old Garden, and Modern Garden roses. WIld, or SpecIeS, roSeS The rose species are endemic to the Northern Hemisphere of the globe only. They have occurred without much deliberate help from man. Fossil evidence from 35 million years ago (the Oligocene epoch) tell us that some rose species did exist at that time. The fossil specimens found most closely resemble the still extant species, R. nutkana, and R. palustris. In Mesopotamia, there have been discoveries of Cuneiform tablets which repeatedly use the word, "amurdinnu", which is thought to mean 'bramble', or 'wild rose'. The historical records of the genus Rosa are rich and many, illustrating that many ancient cultures valued these shrubs as we do now.
rosa canina
The English archaeologist William Flinders Petrie (18531942) discovered in the tombs of Hawara, Egypt, wreaths made of flowers, among them, roses! The wreaths date to about AD 170, and represent the oldest preserved record of a rose species still living. It is believed that the specimens are Rosa x richardii, also known as Rosa sancta (reputedly still to be found in Ethiopia). General characteristics: • flowers: simple, natural looking, usually single-petaled (4-8 petals) • once blooming (non-remontant) • canes: long, arching, fairly well branched • will tolerate a bit more shade (< 6 hours of sun) • shrub size: 2-20' • good at the edge of a woodland

rosa alpina, or Boursault rose
old GArdeN roSeS (oGr) Also known as Antique, Heirloom or Heritage Roses. Defined as any rose belonging to a class which existed before the introduction of the first Modern Rose (hybrid tea), 'La France', in 1867. Characteristics: • once blooming each season • • • •
blooms only on two-year-old canes fragrant double-flowered blooms color: shades of white, pink and red
rare rosa arvensis, or field rose Ayrshire Splendens
A new class of OGR developed in 1800 with the introduction of China and Tea roses: • blooms on new growth • repeat blooms per season (remontant) OGR's are classified in one of the following groups:
• Alba • Bourbon • Centifolia • China • Damask • Gallica
rosa alpina, or Boursault rose
• Hybrid Perpetual • Moss • Noisette • Portland • Tea • Miscellaneous - some climbing classes of old roses (including Ayrshire, Climbing China, Laevigata, Sempervirens, Boursault, Climbing Tea, and Climbing Bourbon) rosa laevigata, the Cherokee rose
135
AlBA • literally "white roses", derived from R. arvensis and R. x alba (R. x alba is a hybrid of R. gallica and R. canina) • This group contains some of the oldest garden roses • flower once yearly in the spring, 4 week duration • flowers are white or pale pink • most have many petals • fragrant • gray-green foliage • shrubby, or can have a climbing habit of growth • disease resistant; won't get black spot
BoUrBoN • originated on the Île Bourbon (now called Réunion) off the coast of Madagascar in the Indian Ocean • believed to be the result of a cross between the Autumn Damask and the 'Old Blush' China rose, both of which were frequently used as hedging materials on the island • first Introduced in France in 1823 • flower repeatedly, but the tougher cultivars are not remontant • vigorous, frequently semi-climbing shrubs • glossy foliage • purple-tinted canes • bloom style: cupped or old rose form • often strongly fragrant • most are highly susceptible to black spot

'Climbing Souvenir de la Malmaison', a bourbon rose
ceNTIFolIA • also known as Cabbage roses, or as Provence roses
• derived from damask roses crossed with albas, raised in the 17th century in the Netherlands. • named for their "one hundred" petals • often called "cabbage" roses due to the globular shape of the flowers • all are once-flowering, 4 week duration • As a class, they are notable for their inclination to produce mutations of various sizes and forms, including moss roses and some of the first miniature roses a centifolia, or cabbage rose
136
cHINA • Based on Rosa chinensis, have been cultivated in East Asia for centuries; cultivated in Western Europe since the late 18th century; AKA: the Bengal rose • They contribute much to the parentage of today's hybrid roses • Compared with the older rose classes known in Europe, the Chinese roses had less fragrant, smaller blooms carried over twiggier, more cold-sensitive shrubs. • Bloom repeatedly throughout the summer and into late autumn, unlike their European counterparts. • Notable for blossom's tendency to "suntan," or darken over time — unlike other blooms which tended to fade after opening. This made them highly desirable for hybridization purposes in the early 19th century. • Tradition holds that four "stud China" roses ['Slater's Crimson China' (1792), 'Parsons' Pink China' (1793), and the Tea roses 'Hume's Blush Tea-scented China' (1809) and 'Parks' Yellow Tea-Scented China' (1824)] were brought to Europe in the late eighteenth and early 19th centuries • shrubby form of shiny foliage • bears large clusters of medium-sized flowers • shades of pink and red
'Parson's Pink China' or 'Old Blush,' one of the "stud Chinas"
dAMASK • Named for Damascus in Syria, Damask roses originated in ancient times with a natural cross Rosa x damascena (Rosa moschata x Rosa gallica) x Rosa fedtschenkoana. • Robert de Brie is given credit for bringing damask roses from the Middle East to Europe sometime between 1254 and 1276, although there is evidence from ancient Roman frescoes that at least one damask rose existed in Europe for hundreds of years prior (6th century). • bloom once in summer • 'Autumn' or 'Four Seasons' damasks bloom again later, in the fall: the only repeat-flowering Old European roses. • sprawling growth habits and vicious thorns • numerous petals of pink or white • have a more loose petal formation than gallicas • strong tangy fragrance. FVTC Example: 'Madame Hardy'

GAllIcA • AKA: Rose of Provins, French roses • Developed from Rosa gallica, a native of central and southern Europe and western Asia. • 'The Apothecary's Rose', R. gallica officinalis, was grown in monastic gardens in the Middle Ages, and became famous in English history as the 'Red Rose of Lancaster'. • flowers once in the summer, 3-4 week duration • flower form is simple or double, large but flat • mostly thornless • all varieties very fragrant • compact shrubs rarely over 4' tall • wide color palette, includes 'rich' or 'intense' shades of pink, red, maroon and deep purplish crimson (almost black) HYBrId perpeTUAl • The dominant class of roses in Victorian England. • Emerged in 1838 as the first roses which successfully combined Asian remontancy (repeat blooming) with the old European lineages. Since re-bloom is a recessive trait, the first generation of Asian/European crosses (Hybrid Chinas, Hybrid Bourbons, Hybrid Noisettes) were stubbornly once-blooming, but when these roses were recrossed with themselves or with Chinas or teas, some of their offspring flowered more than once. The Hybrid Perpetuals thus were something of a miscellany, a catchall class derived to a great extent from the Bourbons but with admixtures of Chinas, teas, damasks, gallicas, and to a lesser extent Noisettes, albas and even centifolias. • They became the most popular garden and florist roses of northern Europe at the time, as the tender tea roses would not thrive in cold climates, and the Hybrid Perpetuals' very large blooms were well-suited to the new phenomenon of competitive exhibitions. • The "perpetual" in the name hints at repeat-flowering, but many varieties of this class had poor re-flowering habits; the tendency was for a massive spring bloom, followed by either scattered summer flowering, a smaller autumn burst, or sometimes nothing at all until next spring**. • blooms all summer, but unreliable** • limited color palette: white, tones of pink and red • large flowers • good fragrance, scent strength varies with cultivar • height variance dependant upon cultivar; shorter compact cultivars less likely to rebloom

MoSS • a mutation of Rosa centifolia, or Damask roses • a large group with varying characteristics • mostly pink, some whites and dark reds • flower looks very similar to Damasks and Centifolias • bear greenish or reddish mossy resin-bearing glands on the sepals that often give off a pleasant woodsy or balsam scent when rubbed • have contributed nothing to the development of new rose classifications • if centifolia background, are once-flowering, 3-4 weeks • if exhibit repeat-blooming, indicative of Autumn Damask parentage • covered with very small thorns, hair-like
NoISeTTe • First Noisette rose was raised as a hybrid seedling by a South Carolina rice planter named John Champneys. Its parents were the China Rose 'Parson's Pink' and the autumn-flowering musk rose (Rosa moschata), resulting in a vigorous climbing rose producing huge clusters of small pink flowers from spring to fall.

porTlANd • original Portland Rose has no Chinese ancestry, but has an 'Autumn' damask/gallica lineage • named after Margaret Cavendish Bentinck, the second Duchess of Portland who received (from Italy about 1775) a rose then known as R. paestana or 'Scarlet Four Seasons' Rose (now known simply as 'The Portland Rose')… whole class of Portland roses was developed from that one rose • The first repeat-flowering class of rose with fancy European-style blossoms • fairly short and shrubby form; has a suckering habit, with proportionately short flower stalks • color palette: pink or red • either semi-double or fully double flowers • main flowering is in the summer, but intermittent flushes continue into the autumn FVTC Example: 'Rose de Rescht' TeA • The original Tea-scented Chinas (Rosa x odorata) were Oriental cultivars thought to represent hybrids of R. chinensis with R. gigantea, a large Asian climbing rose with pale-yellow blossoms. • The British introduced the first two cultivars to the West in 1810 and 1824. • named for their fragrance being reminiscent of Chinese black tea • first grown as greenhouse plants due to fraility of canes and blossoms being susceptible to damage by weather; French hybridizers began cross-breeding seeking improvements • the most important crosses were with the Bourbons; this began a new race of Teas, most of which were quite unlike the old ones: large, vigorous, thick-limbed shrubs, often with perfectly healthy, beautiful glossy foliage • colors range throughout the rose palette -reds, pinks, whites, blushes, yellows, buff, apricot, oranges-, but most special to Teas are the colors of dawn: tones of gold, warm pink, and shadings into each other, with delicate tints and highlightings • flowers semi-pendent and nodding, due to weak flower stalks • pointed buds produce high-centred blooms which unfurl in a spiral fashion, and the petals tend to roll back at the edges, producing a petal with a pointed tip • Teas are thus the originators of today's "classic" florists' rose form... the Hybrid Tea • not hardy in colder climate, need winter protection

ModerN GArdeN roSeS (MGr) Many modern roses have old garden roses in their ancestry. Roses introduced after 1867 are considered Modern Roses, following the introduction of the first hybrid tea, 'La France' by the French breeder Guillot which was considered unique. It possessed the general habit of a hybrid perpetual and the elegant shaped buds and free-flowering character of a tea rose. Breeders recognized planned hybridization could evolve new flower forms, size, growth habit and colors. MGR General Characteristics: • not as highly fragrant as Old Garden Roses (OGR) • more vibrant in color with larger blooms than OGRs
'La France', first hybrid tea introduced in 1867 by Jean-Baptiste Guillot
• most are repeat flowering • not as hardy as OGRs; need winter protection MGR's are classified in one of the following groups:
• Canadian Hardy roses • Climbing/Rambling • English roses • Floribunda and Mini-Flora • Grandiflora • Hybrid Kordesii
Guillot also introduced the first polyantha rose, 'Paquerette', in 1875, 'Mignonette' (above) followed in 1881.
• Hybrid Musk • Hybrid Rugosa • Hybrid Tea • Landscape/Shrub roses • Miniature • Polyantha 'Soleil d'Or', bred by Pernet-Ducher, 1900 Originally considered a separate class, the Pernetianas or Hybrid Foetidas were officially merged into the Hybrid Teas in 1930.

cANAdIAN HArdY roSeS Crosses of native Canadian species and more tender roses, developed by Agriculture Canada at the Morden Research Station in Morden, Manitoba and the Experimental Farm in Ottawa (and later at L'Assomption, Québec). • Developed for the extreme weather conditions of Canadian winters, some down to -31°F (-35°C) • 2 main lines: the Parkland series and the Explorer series • These programs have now been discontinued; however the remaining plant stock has been taken over by private breeders via the Canadian Artists series • other cultivars: Canadian Heritage, Brownell Sub-Zero, Griffith Buck Roses FVTC examples include: 'Morden Centennial', 'Morden Sunrise, 'Winnipeg Parks'
clIMBING/rAMBlING roSeS • Ramblers: - closer to the original wild rose - grow vigorously, can take up a lot of space - typically 7 leaflets, glossy foliage - canes very flexible, arching habit - flower on the previous year's wood - usually they need 2-3 years to start flowering - huge clusters of small flowers, 'Floribunda' style - most have a fragrance - one flush in summer, 3-4 week duration - height: 20'–30' is common - requires awkward pruning rituals in summer, after bloom - some cultivars are evergreen, bear hips • Climbers: - typically 5 leaflets - canes rigidly upright - flowers on new wood - produce fewer but larger flowers - repeat bloom throughout the summer - some have fragrance, some have none - grow between 8'–20' in height - less old wood needs cutting out when pruning

eNGlISH roSeS • started in the 1960s by David Austin of Shropshire, England • Austin desired to combine the best of old and new: - restoring old rose qualities: - romantic old rose form - intense fragrance - shrubbiness - vigor and disease resistance - combined with new rose qualities: - modern repeat-blooming characteristics - larger modern color range Austin largely succeeded, but the typical winter-hardiness and disease-resistance of the classic Old Garden Roses became compromised in the process; many are susceptible to mildew and black spot and need winter protection. FlorIBUNd and MINI-FlorA roSeS FLORIBUNDAS were first developed by the firm of Poulsen in Denmark, with the idea to produce hardy roses suitable for the Scandinavian climate. • 1909, the first Polyantha/Hybrid Tea cross, 'Gruss an Aachen,' was created • first known as Hybrid Polyanthas, until they were re named Floribundas in 1950 • Floribunda: Latin for "many-flowering" • combines the prolific flowering and carefree constitution of the best polyanthas with the many rich colors and nice forms of the hybrid tea roses. • features stiff shrubs, low-growing, smaller and bushier than the average Hybrid Tea but less dense and sprawling than the average Polyantha • flowers are often smaller than hybrid teas but are carried in large sprays • found in all hybrid tea colours and with the classic hybrid tea-shaped blossom • hardier, more free flowering and displaying better disease resistance than the Hybrid Teas • but, susceptible to a myriad of pest and disease problems FVTC Example: Europeana, Shiela's Perfume, Cinco de Mayo, Playboy MINI-FLORA: • intermediate in size and foliage between miniatures and floribundas • A newly introduced class that covers cluster-flowered bush roses less than 2.5 feet tall but larger than Miniatures. • Replaces the common term Patio rose.

roSe prUNING Rose pruning, sometimes regarded as a horticultural art form, is largely dependent on the type of rose to be pruned, the reason for pruning, and the time of year it is at the time of the desired pruning. old GArdeN roSeS Most Old Garden Roses of strict European heritage (albas, damasks, gallicas, etc.) are shrubs that bloom once yearly, in late spring or early summer, on two-year-old (or older) canes. As such, their pruning requirements are quite minimal, and are overall similar to any other analogous shrub, such as lilac or forsythia. Generally, only old, spindly canes should be pruned away, to make room for new canes. One year old canes should never be pruned because doing so will remove next year's flower buds. The shrubs can also be pruned back lightly, immediately after the blooms fade, to reduce the overall height or width of the plant. In general, pruning requirements for OGRs are much less laborious and regimented than for Modern hybrids. ALBA Prune after blooms are all finished. To encourage new growth shorten old branches by about ¼ of their length and shorten any long or lanky canes by 1/3. BOURBON Most varieties require only light pruning. After the first flush of blooms prune the plant to maintain or improve the shape. For climbing varieties see suggestions for climbers & ramblers. CENTIFOLIA Prune after blooms are all finished. Shorten new canes to about ½ their length and shorten any long or lanky canes by 1/3. CHINA Prune hard to about 6” in early spring to encourage new growth leaving only the most vigorous canes. In warmer climates a light pruning to shape the plant will suffice. DAMASKS Once blooming – Prune after the blooms are finished. Remove some old wood to encourage fresh growth and prune to shape. Repeat blooming – Prune in early spring. Select the strongest most vigorous growth and prune it to about 1/3 of its length. Remove all dead, damaged, diseased, broken, weak, or spindly growth. GALLICAS Prune after the blooms are finished. Remove some old wood to encourage fresh growth and prune to shape. The removal of side shoots and the shortening of canes can encourage some Gallicas to “stiffen up” as they grow older and not be so lax.
147
HyBRID PERPETUAL In our area it is advisable to prune modern roses in the spring. Remove all the canes except the largest and healthiest. Cut them back to 3 or 4 good buds, or about 4-6”. Sometimes after a mild winter the canes of these cultivars may be green most of their length. It is still advisable to prune them back to maintain a nicely shaped plant. Hybrid Perpetuals, if not pruned yearly quickly become lanky and bloom production is reduced. MOSS ROSES Once blooming varieties – Prune after spring bloom is finished. Shorted long new growth by ½, remove spindly new growth. Repeat blooming varieties – Prune in early spring. Shorten old growth by about ½ and thin out the branches if there are a lot of them. NOISETTE Noisette grow late in the season so there is likely to be quite a bid of dead wood to remove. Cut back the entire plant by about ¼ and remove spindly and twiggy growth. PORTLANDS Prune in early spring. Select the strongest most vigorous growth and prune it to about 1/3 of its length. Remove all dead, damaged, diseased, broken, weak, or spindly growth. RUGOSAS Rugosas don’t require much pruning except to shape the plant or removal of suspect canes. SPECIES AND OTHER HARDy ANTIQUES Prune after the spring bloom season has passed. Prune these only to maintain a size or shape and to encourage new growth. The more branches on these plants the more the bloom they will produce. ModerN GArdeN roSeS Modern hybrids, including the hybrid teas, floribundas, grandifloras, modern miniatures, and English roses, have a complex genetic background that almost always includes China roses (R. chinensis). China roses were evergrowing, everblooming roses from humid subtropical regions that bloomed constantly on any new vegetative growth produced during the growing season. Their modern hybrid descendants exhibit similar habits; unlike Old European Roses, modern hybrids bloom continuously (until stopped by frost) on any new canes produced during the growing season. They therefore require pruning away of any spent flowering stem in order to divert the plant's energy into producing new growth and hence new flowers. Additionally, Modern Hybrids planted in cold winter climates will almost universally require a "hard" annual pruning (reducing all canes to 8"–12" in height) in early spring. Again, because of their complex China rose background, modern
148
hybrids are typically not as cold hardy as European OGRs, and low winter temperatures often desiccate or kill exposed canes. In spring, if left unpruned, these damaged canes will often die back all the way to the shrub's root zone, resulting in a weakened, disfigured plant. The annual "hard" pruning of hybrid teas, floribundas, etc. should generally be done in early spring; most gardeners coincide this pruning with the blooming of forsythia shrubs. Canes should be cut about 1/2" above a vegetative bud (identifiable as a point on a cane where a leaf once grew). CLIMBERS Climbers should not be pruned in their first or second year in the garden aside from removal of dead, damaged, diseased, broken, weak, or spindly growth. You must begin training the 3 main canes as soon as they reach up to the support structure. Once the growth has reached the structure, train the branches horizontally to encourage the growth of bloom producing side shoots. After the second season one should remove canes that are crossing other main canes and downward growing side shoots. It is also advisable to cut back the length of main canes by about ¼ to encourage new flower producing growth. As the rose grows and gets taller it may become difficult to prune so thoroughly. However, if you can find a way to do it your efforts will be rewarded. Care must be taken when pruning Climbing sports of bush varieties so as not to cause the variety to revert back to bush form. RAMBLERS Ramblers are more vigorous growing than climbers and therefore require a different approach. Prune non-recurrent ramblers in summer after they have bloomed. For the first couple of seasons prune all side shoots from the main branches to encourage vigour. These canes should be trained horizontally (as with climbers) to encourage bloom producing side shoots. After the first couple years and the plant is established remove some of the old growth leaving the most vigorous canes. Train some of the new, fresh growth to fill in the gaps left by removal of the old wood. As ramblers produce an abundance of new shoots from the union it is suggested that one remove the majority of those as they are produced to ensure that the nutrients go to producing growth and bloom where it is most desired. FLORIBUNDA, GRANDIFLORA, HyBRID TEAS, MINIATURE, AND POLyANTHA In our area it is advisable to prune modern roses in the spring. Remove all the canes except the largest and healthiest. Cut them back to 3 or 4 good buds, or about 4-6”. Sometimes after a mild winter the canes of these cultivars may be green most of their length. It is still advisable to prune them back to maintain a nicely shaped plant. SHRUBS AND ENGLISH ROSES Prune shrubs in early spring. Remove weak growth and shorten long canes by about ½. HyBRID MUSKS As Hybrid Musks bloom on new and old wood you can prune liberally in early spring to encourage new growth. Remove
Strong-growing Hybrid Tea. Most of first year's growth (black) from base.
Same bush after light pruning (dotted lines) for many flowers. Stubs removed.
Moderate pruning results in somewhat larger, but generally fewer, blossoms.
For real exhibition-size blooms, in reduced numbers, prune the bush severely.

twiggy growth and very old canes and shorten the length of all the canes by 1/3. For both Old Garden Roses and Modern Hybrids, any weak, damaged or diseased growth should be pruned away completely, regardless of the time of year. Any pruning of any rose should also be done so that the cut is made at a forty five degree angle above a vegetative bud. This helps the pruned stem callus over more quickly, and also mitigates moisture buildup over the cut, which can lead to disease problems. For all general rose pruning (including cutting flowers for arrangements), sharp hand-held, by-pass pruners should be used to cut any growth 1/2" or less in diameter. For canes of a thickness greater than 1/2", pole loppers or a small handsaw are generally more effective; pruners may be damaged or broken in such instances.

plANTING roSeS 1-Composted manure, plus peat moss or leaf mold if the soil is heavy, is dug into the bottom of the hole. 2-Prior to planting any Rose, examine roots for dead and broken portions. Cut off cleanly to live white wood. Spread roots well over a mound of soil and sift soil among them. 3-Arrow points to one typical weak stem that should be pruned back to strong main cane. In general, only three or, at most four, good canes should be left at planting. 4-If main canes of thinned plant before planting are in good condition above point indicated by arching broken line, they may be only moderately trimmed. Otherwise cut back to point of line. 5-In the process of filling around roots with good fertile soil, make sure that swelling of "bud" or graft will be just below final level of soil after plant is firmed in place. 6-Roots must be put in very firm contact with surrounding soil. Hence when they are well covered, step into planting hole to pack soil. If job is done right, "bud" will be in correct position. 7-After tramping soil, fill rest of hole with water if ground is dry at planting time. When hole has drained, fill with loose, dry soil to final level. 8-Final step in planting is mounding up base of canes to depth of from 4 to 8 inches with clean soil, free from large lumps. If planting in spring, leave in place for at least ten days, then pull it away from canes gradually. In fall planting, it is left until the spring. 9-After ground is thoroughly warm and plant established (mid-to-late May), it is helpful to mulch surface with peat moss or similar porous material. This keeps down weeds, keeps roots cool and moist during heat. 10-In cutting Roses for the house, or after blooms have faded, leave at least two sets of five-part leaves for later bloom. The more foliage you leave on plant, the healthier it is likely to be, this year and after. 11-Some gardeners cut back plants at approximately this line after peak of June bloom. In general this gains nothing, may be harmful. However, straggling growth should be removed before winter winds and snows.

deAdHeAdING roSeS The theory is that when you remove the bloom before the plant is able to form seed pods (rose hips), the plant will want to put out more blooms in its drive to reproduce. Most modern roses will rebloom about 6 weeks after you remove the old dead blooms. Some in as little as 4 weeks, and some will take up to 10 weeks to rebloom. The Traditional technique is to cut the cane down from the spent bloom to 1/4 inch above the first leaf cluster with 5 leaflets using hand pruners. Using this technique you can also prune further down the cane to the bud that is pointing in the direction you want the branch to grow. The plant will grow in the direction that the bud is facing. The current advice from experimental gardens in the RNRS (Royal National Rose Society) headquarters at St. Albans is to nip off the dead flower just at the neck. This Conservative technique will promote immediate growth and a quicker return to flowering. All blooms were snapped off at the peduncle when flowering was complete, leaving the maximum amount of foliage remaining on the plant. This foliage was very important for maximum photosynthesis to take place. It was noted that the bushes that received "flower only" deadheading produced more basal breaks earlier than the bushes that received the five leaflet deadheading and removal of blind growth. This technique results in more branching. Virtually every flower will result in a new branch, and those new branches will all terminate with new flowers. The tradeoff is that you will have more blooms, but slightly smaller blooms. Those who want to competetively exhibit their blooms should not use this second method. Conservation of all foliage is extremely important, and includes the leaves on blind shoots and twiggy growth. All make significant contributions through photosynthesis and should be retained unless they interfere with growth of healthy new canes. MODERN ROSES, EXHIBITION AND DEADHEADING - the further down the stem you cut, the larger the bloom stem and subsequent buds will become, and hence, the longer it will take for the rose to rebloom. - the subsequent bloom stem will be slightly smaller than the stem you have just removed. And deciding how far down the stem to make that cut is best determined by using good judgment.
- growing a Hybrid Tea and religiously disbud, then deadheading further down the stem should be tempered with how large you expect the second bloom to become and how soon you want the rose to recycle. In general, you should stop deadheading about 6 weeks before the killing frosts occur in your area. If you are in an area without a true winter you might want to stop about 6 weeks before you introduce some sort of artificial dormancy, whether that is by defoliating or hard pruning of the plants.

Clematis
Family: Ranunculaceae The name ‘clematis’ comes from Ancient Greek ‘klématis’, a climbing plant (probably periwinkle). AKA: Traveller's joy, Old man's beard, Virgin's bower. Clematis was called pepper vine by early travelers and pioneers of the American Old West and used as a pepper substitute to spice up food since true black pepper (Piper nigrum) was a costly and rarely obtainable spice. The entire genus contains essential oils and compounds which are extremely irritating to the skin and mucous membranes. Unlike black pepper or Capsicum, however, the compounds in clematis cause internal bleeding of the digestive tract if ingested in large amounts. The plants are essentially toxic. When pruning them, it's a good idea to wear gloves. Despite its toxicity, Native Americans used very small amounts of clematis as an effective treatment for migraine headaches and nervous disorders. It was also used as an effective treatment of skin infections.
OVERVIEW Clematis are a varied group of mostly woody, deciduous vines, though Clematis armandii is evergreen and a few are herbaceous perennials. Hundreds of species and thousands of varieties are available. Their bloom time ranges from February or March until frost. The fruit is often showy as well, being a ball-shaped, "feathered" structure. As cut flowers, clematis are longlasting. The seedpods are used in dried flower arrangements. Butterflies and hummingbirds are attracted to clematis. FlOWER FORMS There are three general flower forms: • small white flowers in loose clusters • bell or urn-shaped flowers • flat or open flowers HEIGHT/SPREAD Size of different clematis varies considerably: • small herbaceous species: 2-5 feet tall • large-flowered hybrids: 8-12 feet tall • vigorous species: 20-30 feet GROWTH RATE Growth may seem slow as the plant builds its root system, but once established, clematis are strong growers. ORNAMENTAl FEATURES • leaves: opposite, divided into leaflets, and leafstalks that twist and curl around supporting structures to anchor the plant as it climbs • bloom size: 4-10" in diameter • profusion: as many as 100+ blooms/plant • wide color range: white, blue, violet, purple, pink, red and bicolors
FRAGRANCE Species: many have fragrant blooms, a range of fragrances from almond to hot cocoa Hybrids: usually no scent CUlTURE • Full Sun - 6 hours/day to flower best - some afternoon shade prevents fading of red, blue, bicolored hybrids; Eastern exposure best for these • Soil: - well-drained, organically rich - avoid extremely wet locations • Transplant: - protect from strong winds - cut stems back to 12"; stems quite fragile until several years old - keep root zone cool; 2" layer of mulch - crown of plant: 2-5" below surface (allows plant to recover if becomes damaged or infected with wilt) - provide support for vine - water deeply; 1" per week minimum - do not fertilize during flowering • Pruning: - 3 types or groups: Group A - Early Flowering Group B - Large-Flowered Hybrids Group C - Late Flowering - depends mainly on types' flowering time - detail provided in group section DISEASE/INSECTS • Fungal stem rot and leaf spot/clematis wilt - mainly affects large-flowered hybrids • powdery mildew • aphids, mites, slugs • rabbits and mice 153 - feed on the stems, girdling them

PRUNING ClEMATIS Pruning encourages branching and helps develop more plentiful blooms. It should be accomplished between the end of February to the beginning of April. Pruning later than April will result in a delay of blooming. "You cannot kill a clematis by pruning it, and there is no wrong time. The worst that will happen is that your clematis will bloom later than normal." Linda Beutler Curator of the Rogerson Clematis Collection, West Linn, OR and author of Gardening with Clematis. • Prune with sharp garden shears, .25" above a set of two healthy leaf buds blooming. • Always remove all withered leaves and either whole stems or just the parts that died down • During the first year for all clematis: cut no higher than 12" from the base, to encourage the growth of new stems at the base of the vine • Similar, or even better results can be obtained by laying the stems flat on the ground and covering them with mulch. It will foster the strength of the plants and thus ensure better flowering and higher immunity to diseases.
Pruning: Group A
• In subsequent years, pruning depends on the variety and the season in which it blooms: Group A (A = After bloom) — none - Varieties that flower only on growth produced the previous year: Clematis montana, Clematis alpina and Clematis macropetala. - They are generally not pruned at all, but if it is necessary to prune some overgrowth, cut immediately after flowering, usually not lower than 3' above the ground. Group B (B = Before bloom) — light - The large-flowered varieties that begin to bloom in May or early June with the first flush of flowers appearing on the previous year's growth, followed by a smaller flush on new growth. - New plants: Hard-prune (to about 12 inches) for the first two years after planting to develop a strong root system. - Prune in spring, cut back to a set of live buds, about a third down from the top or a height of 3-5' from the base.
