ARABIS

(origin of the word not clear). Wall Cre ; Rock Cre . O RD. Cruciferæ. Hardy perennial trailers, except where otherwise stated. Flowers mostly white; racemes terminal; pedicels bractle . Radical leaves usually stalked; cauline ones se ile or stem-clasping, entire or toothed, rarely lobed. Most members of this genus are peculiarly well adapted for rockwork and the alpine garden, both from their natural hardihood as well as their early and profuse flowering habits. They are of the easiest po ible culture in any dry soil. The perennial species may either be increased by divisions of the root, by cuttings, placed in a shady border during the summer, or by seed. The latter may be sown outside, or in pans, in spring, when most of them will germinate in two or three weeks. The annuals and biennials are for the most part devoid of any cultural beauty.
