Wall Rock Cress

Wall Rock Cress
Arabis caucasica
Synonym: alpina subsp. caucasica

An alpine perennial Arabis is especially good for rock gardens and the edging of borders. It forms a nice mound of foliage and a early spring a carpet of flowers. The flowers are fragrant and remind me of Sweet Alyssum. There are many species available but this one seems to be, in my experience, the most available.

Like most alpine plants there is a requirement for good drainage. The winter drainage is most important for keeping a patch going but it will not tolerate poor drainage in the summer either. It’s low maintenance only requiring a light shearing after blooming and we raked it out at the end of the season.

In this picture on the timbers that forms an edge of a rock garden. The Rock Cress has grown right up to the wood and formed a carpet.
