Orchids seem to do best if a greenhouse is devoted solely to their cultivation, though some types such as Odontoglossum grande and Coelogyne cristata will succeed very well in a general collection of plants.

Commemorating Paeon, an ancient Greek physician, is said to have first used P. officinalis medicinally. Although the genus has long been considered a member of the buttercup family, Ranunculaceae, some modern botanists now place it in a family of its own, Paeoniaceae. A genus of 33 species of hardy herbaceous and shrubby perennials and a few shrubs, among the noblest and most decorative plants for a sunny or shaded border. The main division of the genus is between the herbaceous and the tree paeony, but botanically, the matter is much more complex.
Beans include many types of snap beans, pole beans, and Southern peas, such as black-eyed types. Plant these in spring after all danger of frost has passed. Because they grow so fast, start beans from seed directly in the garden. To speed their sprouting, soak seeds in water overnight before planting.
Climbing leaf-losing shrubby plants, from Brazil, which belong to the family Nyctaginaceae. They are cultivated outdoors in the far South and in colder climates in greenhouses. The slender woody stems are furnished with small, ovate to elliptic-lanceolate, green leaves and sharp thorns.
From the Latin salveo, meaning save or heal, used by Pliny with reference to the medicinal qualities of some species (Labiatae). A large genus of over 700 species of hardy, half-hardy and tender annual, biennial, perennial plants and shrubs, some with aromatic leaves, widely distributed in the temperate and warmer zones. It includes the common sage, S. officinalis, a valuable culinary plant, as well as many colourful summer and autumn flowering border plants.
From the Greek dolphin, a dolphin, the flowerbuds having some resemblance to that sea creature (Ranunculaceae). Larkspur. The genus consists of annual, biennial and herbaceous perennial plants, mostly hardy and showy plants for border cultivation, with some dwarf species suitable for the rock garden.
African violet is perhaps the only full-blown paradox that can survive on a windowsill. On one hand, it is a celebrated show plant, with new cultivars eagerly sought after by collectors and enthusiasts. It has its own organization, the African Violet Society of America, and its own magazine, African Violet. A quick Internet search reveals that there are almost as many African violet sites as there are pages for sex and dieting. And yet, these plants are mass-produced by the hundreds of thousands and are readily available for a minuscule price from mom and pop garden centers, enormous mega-merchandisers, and a host of medium-size vendors.
Possibly from the Latin barba, a beard, many species have a hairy or downy look (Scrophulariaceae). Mullein. A genus of 300 species of hardy herbaceous plants, mostly biennials or short-lived perennials, from temperate parts of Europe and Asia.
Named for Karl August von Bergen, 1704-60, German botanist (Saxifragaceae). These hardy perennial herbaceous plants with large evergreen leaves were at one time called megasea, and were at another time included with the saxifrages. The flowers which come in early spring are showy in white, pink or red-purple, borne in large heads on long stems. The large leathery, glossy leaves are also decorative, especially as in some kinds the foliage is suffused with reddish color in winter.
From the Greek pyr, fire, probably with reference to fever, since the plant was used medicinally to assuage fever (Compositae). These hardy plants are admirable for a sunny border and last well as cut flowers. Long known as pyrethrum they are botanically classified under Chrysanthemum.
