See text Arabis /ˈærəbɪs/,[1] or rockcress, is a genus of flowering plants, within the family Brassicaceae.

The species are herbaceous, annual or perennial plants, growing to 10–80 cm tall, usually densely hairy, with simple entire to lobed leaves 1–6 cm long, and small white four-petaled flowers.

Natural habitat for Arabis species is rocky mountain/cliff sides or dry sites.

[2] Though traditionally recognized as a large genus with many Old World and New World members, more recent evaluations of the relationships among these species using genetic data suggest there are two major groups within the old genus Arabis.

[3][4] Some species, notably Arabis alpina, are cultivated as ornamental plants in gardens.
