RANUNCULACEAE 15-18 inches 12-18 inches clump forming groundcover 3-8, heat 8-1

LONGEVITY:

generally long lived, but takes a long time to get established

FOLIAGE:

palmate, serrate margins, leathery, glossy, basal, dark green, 7-9 segments; often evergreen; leaves, stems & roots are poisonous; deep rooted

FLOWER:

showy clusters; white, cream, yellow, pink, purple; spotted or unspotted; 2.5-4� dia., saucer-shaped, 5 petals (actually sepals), somewhat nodding

BLOOM TIME: BLOOM LENGTH: LIGHT: SOIL: MOISTURE: PROPAGATION: USES: MAINTENANCE: PROBLEMS: COMMENTS:

Varieties

early Spring; late March through May 8-10 weeks part to full shade; performs better if given some sun rich, moist, well-drained; highly adaptable, tolerates a variety of conditions; amend soil with composted leaves medium; drought tolerant once established division in fall, heavy fibrous roots need careful handling; self sows in right location

Habit

woodland or shade garden, groundcover, border, naturalized area low; fertilize in early spring; only cut back any damaged foliage; to increase self sowing do not deadhead control slugs; occasional leaf spot and crown rot Native to Greece, Turkey, Caucasian Russia. Two main helleborus horticulture groups: caulescent (having above ground stems; more short lived, 3-4 years; not as easily propagated by division) and acaulescent (without visible ground stems). Extracts from hellebores have been used in homeopathy and traditional medicines in several countries; as an herb for weight loss in Russian. Most Lenten hellebores in gardens are now considered to be H. x hybridus. All plant parts are poisonous.

PROPAGATION:

seed (some self sowing), tip cuttings, layering; offshoots occur after 3 years

USES:

mid-border, mass plantings, herb garden, strong vertical element, cut flower, foliage color, late summer color, winter interest

MAINTENANCE:

do not fertilize as will tend to get floppy; in spring, cut back to 12 inches, do not cut into woody stem; can cut back by half in early summer for stouter plants but this also delays the bloom time

PROBLEMS:

plants tend to sprawl or flop over as summer progresses, particulary if not in full sun; pest resistant; mold, stem blight

COMMENTS:

Native to central Asia including Afghanistan, Iran, Pakistan and Tibet. Named for a 19th centure Russian general, V.A. Perovski. Relatively unknown as a landscaping plant until the 1990s. In native habitat, flowers are eaten fresh, and leaves are smoked like tobacco for its euphoriant properties.

Vinca, Latin, vincio which translates ‘to bind’ referring to the stems; minor, small, referring to the foliage size. Dried leaves used medicinally to enhance blood circulation and treat cardiovascular disorders. The color name, periwinkle, is derived from the flower. The association of vinca with death is most ancient, worn as wreathes in human sacrifices and to garland criminals in the Middle Ages being hung from scaffolds. Culpepper wrote of the old tradition of a man and woman eating vinca together as it would forever bind them in love, and bless them with fertility.

Foliage close-up

aphids, spider mite; powdery mildew Native to Asia and northeastern Europe. Genus name derived from Greek, chrysous meaning gold, and anthemon meaning flower. Prior to 1999, this genus was included within the genus Dendranthema. First cultivated in China as a flowering herb since 15th century. Renowned as one of the Four Gentlemen in chinese and East Asian art (the others being the plum blossom, orchid and bamboo). C. x moriflolium derived primarily from C. indicum. Petals of the yellow or white varieties are boiled to make a sweet tea, call chrysanthemum tea, which aids in the recovery from influenza due to its antibacterial and antimycotic properties. The leaves are steamed or boild and used as greens, especially in Chinese cuisine. In some countries this flower is symbolic of death, lamentation and/or grief. In other countries it represents honesty.

leave seedheads for winter interest must be kept moist Native to eastern North America. First described by botanists in 1705. Species has a history of taxonomic uncertainty; Linnaeus designated genus as Actaea, the was later revise by Thomas Nuttall to Cimicifuga based solely on the dry follicles/fruit appearance; now revised back to Actaea. Roots and rhizomes used medicinally by Native Americans; extracts possess analgesic, sedative and antiinflammatory properties. Black cohosh preparation today used mainly to treat menopausal hot flashes. The root was an official drug of the US Pharmacopoeia from 1820 to 1926. Some consider the fragrance unpleasant, earning it a reputation as an insect repellant plant, thus called Bugbane.

may become invasive; leaf fust Native to North America. Genus name derived from Latin, solidus, whole, and ago, resembling or becoming, referring to the healing properties of this plant. Goldenrod has been wrongly accused of causing allergies and hay fever; it is actually Ragweed that is the culprit, which blooms at the same time. Have long been considered by Americans as weeds, but prized as garden plants in Europe; have gained some acceptance in American gardening since the 1980’s. Inventor Thomas Edison experimented with goldenrod to produce rubber, which it contains naturally only in its leaves; his experiments produced 12’ tall plants yeilding up to 12% rubber; tires on the Model T given to him by friend Henry Ford were made from goldenrod. Native Americans chewed the leaves to relieve sore throats and chewed the roots to relieve toothaches.

Foliage of ‘Colorata’

Euonymus Scale, often slowly lethal unless treated with pesticides and/or dormant oil; unsightly as a white or gray ‘powder’ on the stems and underside of foliage; retains blown leaves due to the numerous low, upright stems and retentive foliage Native to China. Garbage and dead leaf collector (due to low branching). Euonymus translates as “good name” (used ironically, since the genus once had a bad reputation for poisoning cattle). fortunei is named for Robert Fortune, a botanist who collected plants from 19th century China.

Grasses Ornamental Grasses have two classifications: Cool Season —

beginning to grow in spring, flower in early summer, grow best between 60-75°, go dormant or begin to grow slower in heat are often evergreen, and require more moisture.

Warm Season —

grow best when temperatures reach 80°, flower in late summer, go dormant in cold weather, provide the most colorful autumn display, and, left standing, provide good winter interest.

In the landscape, ornamental grasses add: height, texture, movement and susurration.

Habit ‘Blond Ambition’

Native to western North America. ‘Blond Ambition’ discovered and introduced by David Salman of High Country Gardens. Often blooms and sets seed fIrst year. Seed set often low. Plants tolerate moderate grazing and trampling. This bunch grass was an important plant for retaining the soil. When much of it was plowed under for agriculture, the loss of the root structure contributed to the Dust Bowl in the 1930’s. Named “Eyebrow Grass” because the flowers resemble an eyebrow floating on thin stems.

Flowers close-up

plant will wilt quickly if soils are allowed to dry out; avoid overhead watering to prevent powdery mildew; no serious insect or disease problems; watch for aphids, whiteflies; root rot in poorly drained soils Native to Central America and Mexico. Ageratum has evolved an ingenious method of protecting itself from insects; it produces a precocene compound which interferes with the normal function of the corpus allatum, the organ responsible for secreting juvenile hormone. This chemical triggers the next molting cycle to prematurely develop adult structures, and can render most insects sterile if ingested in large enough quantities. Is toxic to grazing animals, causing liver lesions. Has become an invasive weed in eastern US, Australia, Europe, Africa, China, Japan and New Zealand.

Amarantos, Greek, meaning unfading; anthos, Greek, meaning flower; Many parts of the plants, including the leaves and seeds, are edible, and are frequently used as a source of food; a grain crop in India and South America. Used in Thai cuisine, known as Pak Khom. Flowers retain some color when dried. Do not eat this plant if it is treated with synthetic fertilizers as the leaves will concentrate nitrates in nitrogen rich soils; nitrates contribute to stomach cancers, blue babies and other health problems; eat only organically grown. Seed is very nutritious; eaten cooked, ground into a powder, used in baking, can be popped like popcorn. Contains 13-18% protein, rich in the amino acid lysine; contains good quantities of calcium, phosphorus, iron, potassium, zinc, vitamin E, and vitamin B complex. A red food coloring called ‘betalaina’ is obtained from the red cultivars. All members of this genus photosynthesize by a more efficient method than most plants: C4 carbon-fixation pathway.

SCORPHULARIACEAE

Habit

June-October (frost) continuous Full Sun rich, humic, well-drained consistently moist; not drought tolerant seed groundcover, hanging baskets; window boxes, low walls, rock gardens

‘Giant Snow Flake’ close-up

low plants frequently tend to slump or succumb to the heat of summer, but if they survive, they may return to flower in autumn; recovery from severe drought stress is poor; white flies; root/stem rot in wet soils Native to South Africa. Much confusion as to the taxonomy of this group has arisen from the erroneous 
classification of the first cultivar to be widely grown, Sutera cordata ‘Snowflake’, under the incorrect species names Bacopa cordata or Bacopa monnieri (the Water Hyssop); this confusion is still present in much of the literature and appears to be even further muddied by the fact that many of the newer cultivars with a wider range of flower colors are of hybrid origin among two or more species; 
Bacopa genus is an aquatic plant, family Plantaginaceae, commonly called water hyssop and often used in freshwater aquariums.

‘Tokyo Pink’ close-up

low to none pest and disease free Native to coasts of north Africa and Europe. All members of the genus Brassica contain very high levels of antioxidant and anticancer compounds. Some authorities say that kale has the highest concentrations of all. Some of these compounds enhance antioxidant and detoxification effects in the body. Others inhibit tumor growth; some block cancer causing compounds, and some prevent the formation of carcinogens. It has also been reported that compounds in brassicas can protect the eyes against macular degeneration. The earliest records of cabbage being cultivated for food come from the Greeks around 600 BC. Note: some include collards under this genus/ species, but that is incorrect as they are not ‘head’ producing.

PROBLEMS: COMMENTS:

Habit

flowering suffers if soils are too fertile Native to Madagascar. In frost-free climates it develops a woody stem near the base and can get 2-3’ tall with equal spread. The species has long been cultivated for herbal medicine and as an ornamental plant. In traditional Chinese medicine, extracts from it have been used to treat numerous diseases, including diabetes, malaria, and Hodgkin’s disease. The substances vinblastine and vincristine extracted from the plant are used in the treatment of leukemia and other cancers. Conflict between historical indigenous use, and recent patents on C.roseus-derived drugs by western pharmaceutical companies, without compensation, has led to accusations of biopiracy. It can be dangerous if consumed orally. It can be hallucinogenic, and is cited (under its synonym Vinca rosea) in Louisiana State Act 159. Its alkaloids are hypotensive, sedative and have tranquilising properties and are anti cancerous. It helps in relieving muscle pain, depression of central nervous system and wasp stings. Grown commercially for its medicinal uses in Australia, Africa, India and southern Europe.

Genus name from Greek, di meaning two and askos meaning bag, pouch or sack; does not refer to the spurs, but to the two translucent sacs know as ‘windows’ found in the upper part of the corolla of the original type specimen. The spurs of the flower contain a special oil, which is collected in the wild by certain species of bees (Rediviva) that appear to have co-evolved with the plants, as they have unusually long hairy forelegs for collecting the oil. The ‘windows’ may help the bees to find the correct position within the corolla when gathering oil from the glands within the spurs.

Hummingbird attractor

aphids, whitefly, spidermite Native to Central and South America. The first to be cultivated, Fuchsia triphylla, was discovered on the Caribbean island of Dominican Repulic/Haiti in 1703 by the French Minim monk and botanist, Charles Plumier. He named the new genus after the renowned German botanist Leonhart Fuchs (1501–1566). While the original pronunciation from the word’s German origin is “fook-sya”, the standard pronunciation in English is “fyusha”. As a consequence, fuchsia is often misspelled as fuschia in English. Called Chilco, in South America, meaning “that which grows near the water”, it’s natural habitat being along streams and lakes.

Native of South Africa. The genus name Gerbera is in honour of the 18th century German naturalist Traugott Gerber, and the species was named after Robert Jameson who collected live specimens while on a prospecting expedition to the Barberton district in 1884, even though the species had been collected on three earlier occasions by other people. The breeding of Gerbera started at the end of the 19th century in Cambridge, England, when Richard Lynch crossed G. jamesonii and G. viridifolia. Most of the current commercially grown varieties originate from this cross.

Flower and seedhead close-up

staking may be needed no serious insect or disease problems Native to Central America. First domesticated in Mexico by at least 2,600 BC; earliest in North America, in Tennessee around 2,300 BC. Sunflower seeds were brought to Europe from the Americas in the 16th century, where along with sunflower oil, they became a widespread cooking ingredient. Leaves of the sunflower can be used as cattle feed, while the stems contain a fibre which may be used in paper production. Sunflowers can be used in phytoremediation efforts as they extract toxic ingredients from soil, such as lead, arsenic and uranium, and were used after the Chernobyl disaster to remove cesium-137 and strontium-90.

Flower close-up

whiteflies, spider mites (particularly in greenhouse); unripe berries and foliage are toxic to livestock Native to the American tropics: Mexico, Central America, Bahamas, Columbia, Venezuela. Is considered an invasive species in many tropical and sub-tropical areas, including Florida, Texas, Hawaii. Extracts of the fresh leaves are antibacterial and are traditionally used in Brazil as an antipyretic, carminative, and in the treatment of respiratory system infections. Produces allelopathic substances in roots and shoots, increasing its competitive ability; tolerates fire by regenerating from basal shoots.

Bulbs Bulbs are either Hardy or Tender. Hardy Bulbs:

are planted in the autumn, can overwinter in the ground, and bloom in spring to early summer

Tender Bulbs:

are planted in spring, must be lifted and stored for winter, and bloom in summer to early autumn

Bulbs can be divided into 5 categories: True Bulb:

an underground modified leaf bud; consists of a short, thick stem & flesh scales, serves as a food storage unit; has a point on top & basal plate, and is covered with a papery tunic

Corm:

a stem that is modified into a mass of undifferentiated storage tissue; the leaves and flowers emerge from buds on the stem; it has a round and slightly flattened appearance and is covered with a fibrous tunic

Tuber:

cell structure is a stem; usually oblong or rounded with visible nodes from which new plants arise

Rhizome:

thickened branching storage stems that are solid but lack a tunic; they grow laterally at or just below the soil surface; roots develop on the underside, shoots from buds along the top

Tuberous Root: cell structure is a root; typically grow in a cluster; the end formerly attached to the plant has crown tissue that produces buds which grow into new stems and foliage, the other end produces fibrous roots

HYACINTHACEAE + ASPARAGACEAE

Characteristics overview

April-May 6-8 weeks Full Sun sandy-loam, well-drained moderately dry seed, division of offsets; cutting crosswise slits on a mature bulb before planting will stimulate production of offsets; will take a new offset bulblet 2-3 years to reach flowering size

Flowers in a wide array of colors

borders, beds, mass planting, containers, rock gardens replace bulbs every 2-3 years to ensure large, high-quality flowers; let overwintering bulbs dry out no serious pest or disease problems Native to eastern Mediterranean and northern Africa. Introduced to Europe in 16th century. In Greek mythology, Hyakinthos was a young man admired by Apollo and Zephyr, but killed by a discus in a jealous fight between the two gods; a flower was allegedly named after him when it sprang from his blood. Essential oil obtained from flowers is used in perfumery. Contact with hyacinth bulbs or sap can cause severe skin irritation in certain sensitive people, and all parts cause stomach pains if ingested. Fragrance can irritate those with asthma.

COMMENTS:

Habit

Native to Ryukyu Islands, Japan and Taiwan. Prior to 1941, most bulbs were imported from Japan; supply suddenly cut off after the attack on Pearl Harbor causing Easter lilies to become extremely valuable in the US for commercial production. Now, 95% grown by just ten farms in Oregon and California. 4th largest crop in wholesale value in US pot plant market behind poinsettias, mums and azaleas. This crop is known as the “wheelbarrow” crop as it is continually being moved from cool to warm and back depending on how fast or slow it is growing that particular season, with different bulbs responding differently; much research has been done on timing for commercial production, with leaf and bud counting, and graphical tracking often used. Since the beginning of time, lilies have played significant roles in allegorical tales concerning the sacrament of motherhood. Symbolic of purity and grace throughout the ages.

Cultivar examples

pest and disease free Native to Europe, North Africa and Asia. Two dreivations of the name: 1) a youth of Greek mythology called Narcissus, who became obsessed with his own reflection as he gazed into a pool of water that he fell in and drowned; this plant first sprang from where he died. 2) from Greek, narkao, meaning ‘I grow numb’ referring to the plant’s narcotic properties. Bulbs contain the poison lycorine; sap of some cultivars can cause dermatitis. Daffodils are grown commercially near Brecon in Powys, Wales to produce galantamine, a drug used to combat Alzheimer’s disease. Narcissus/daffodils have been recorded in history as early as the 2nd century BC. In the landscape

Habit

evenly moist when foliage present; heavy feeders: regularly fertilize; not drought tolerant division after growth has started in spring borders, containers, groundcover Each caladium tuber has a large, central bud surrounded by several small buds. If the large, central bud is allowed to grow it will prevent the small buds from growing and producing leaves. Use the tip of a sharp knife to lift out the large, central bud, being careful not to injure any of the surrounding small buds. De-eyeing will stimulate the production of a greater number of, but slightly smaller, leaves. Lift before frost; do not water soil when tubers are dormant; if planted too early in spring, cool soil temps will cause tubers to rot before they sprout: start indoors 4 weeks before planting outdoors

In flower

slugs, snails; tuber rot, leaf spot, leaf burn, gray mold, stem rot Native to Brazil and other areas of central and south America. Have been in cultivation in Europe since the late 18th century. Currently, approximately 98% of all caladium bulbs are from Lake Placid, Florida. All parts of the plant are poisonous.
