Snowcap Rock Cress

Arabis alpina subsp. caucasica 'Snowcap' is a low-growing perennial prized for its profusion of small, pure white flowers that blanket the foliage in early spring. This compact cultivar forms a dense mat of evergreen foliage that remains attractive year-round, with narrow, dark green, slightly serrated leaves creating a neat, uniform appearance. In early to mid-spring, 'Snowcap' produces an abundance of small, four-petaled flowers that completely cover the plant, creating a stunning display and attracting bees and butterflies.

Design tip

Allow this compact groundcover to spill gently over retaining walls, stone steps, or raised beds where its cascading habit softens hard edges. The flowing effect creates a natural transition between masonry and surrounding garden plantings while adding early-season charm.
