whitlow grass

any plant belonging to either of two genera (Erophila and Draba), of the mustard family (Brassicaceae); some authorities believe that all these plants belong to one genus, Draba. The genus Erophila contains 10 European species, the genus Draba about 300 species distributed throughout the New World in the north temperate region, the Arctic, and mountainous areas. The European common whitlow grass (E. verna), a low annual with small rosettes of narrow leaves, has clusters of white flowers at the ends of leafless stems and bears spear-shaped fruits on long stalks. It has many varieties and is naturalized in northern North America, where it grows on mountains, sandy ground, and rock walls. Yellow whitlow grass (D. aizoides) is similar but with yellow flowers; twisted, or hoary, whitlow grass (D. incana) and the smaller D. norvegica have leaves on the stems and white flowers with notched petals. All bloom in the spring
