- Description
-
This showy, sprawling evergreen perennial is native to crevices of limestone rocks, along streams and in calcareous alpine meadows of Europe. It has naturalized in Canada and parts of the northern U.S. Ideal conditions for growth include a location with full sun and gritty, alkaline, well-drained soil. Once planted, it is advisable to let the plant remain in that spot as it does not like its roots disturbed.
The sweet-scented flowers are typically white, however, varieties pink or rose. Cut back foliage after bloom to promote denser growth habit. This will also encourage healthier foliage growth. Failure to cut back can lead to long, bare branches with foliage only appearing at the ends, and will also limit the spread of its rhizomes.
The leaves are edible, primarily used as a garnish.
Wildlife Value: Members of the Arabis genus support the following specialized bees: Andrena (Scaphandrena) arabis. This plant is deer and rabbit resistant.
Insects, Diseases, and Other Plant Problems: No serious insect or disease problems. Aphids are an occasional issue. Root rot, white rust, and downy mildew may occur in overly moist or poorly drained soils. Plants tend to suffer in summer heat south of Zone 6.
