Draba (Greek name for a cress). Cruciferae. WhitLow-grass. One of the important groups of spring- flowering plants for the alpine garden. A large and widely scattered genus of tufted hardy annual or perennial herbs, with stellate hairs: lvs. often in a rosette, mostly uncut: scapes or sts. leafy or not; racemes short or long; fls. without bracts, small, white, yellow, rosy or purple; stamens 6: fr. an oval, orbicular or linear flat pod with several to many marginless seeds in 2 rows in each cell; cotyledons accumbent.— Some 150 species in temperate and arctic regions of the world, many of them in mountains. Many species occur in the lists of alpine gardeners. They are more or less alyssum-like. Drabas are very pretty dwarf compact alpine plants, with small but numerous flowers admirably adapted for the rockery or front part of a sunny border. They require a sunny position and an open soil. It is important that they be well matured by the autumn sun. The plant forms a dense little rosette of lvs., and has a neat appearance at all times. In spring, drabas are thickly covered with their little flowers and when planted in masses are decidedly effective. Propagation is chiefly by division; also by seed, which may be sown in the fall if desired. (J. B. Keller.) D. borelis. DC.
