Arabis
''Arabis'' ,''Sunset Western Garden Book,'' 1995:606–607 or rockcress, is a genus of flowering plants, within the family Brassicaceae. Description 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. The fruit is a long, slender capsule containing 10-20 or more seeds. Natural habitat for ''Arabis'' species is rocky mountain/cliff sides or dry sites. Cultivation of ''Arabis'' is best suited for rock gardens or container gardens. This genus is pollinated by members of Apieae and Lepidoptera. Taxonomy 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''. These two groups are not each other's closest relatives, so have been split into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arabis Hirsuta
''Arabis hirsuta'', known as hairy rock-cress, is a flowering plant in the family Brassicaceae. In previous North American works, this species has been broadly defined to include plants native to Europe, Asia, and the northern half of North America, but is now more often restricted to a narrower subgroup restricted to Europe. ''Arabis hirsuta'' grows to heights of up to around and is usually unbranched, with a long spike of flowers. Lower leaves form a rosette, the stalkless upper-leaves clasp the stem. The white petals are twice as long as the sepals, flowers June–August. The fruits are cylindrical and pressed close to the stem and the slightly winged seeds are reddish brown. It features hairs, which are stiff and forking. The species grows on chalk slopes, dunes, hedgebanks, walls and rocks. The conservation status of ''Arabis hirsuta,'' in the UK, is marked as "least concern A least-concern species is a species that has been evaluated and categorized by the Internat ...
