Rock Cress
By Lou Paun
Rock Cress (Arabis) - A large family of hill-plants, few of which are grown. A. albida (White Rock Cress) will grow in any soil, where its sheets of snowy bloom may open in early spring. The double white form is a favourite.

 


Rock Cress is easy to grow. Grow Rock Cress in full sun. Plants will tolerate a light or partial shade. They will do well in fair to poor soils, with a neutral to slightly alkaline pH. Sandy, loam, or clay soil is fine.

Lyre-leaved rock cress is food for larva of the falcate orange-tip butterfly. The butterflies tend to visit the plants around the time of flowering.
