ARABIS caucasica compacta Snowcap (Snowcap Rockcress) Rockcress is a widely planted rock garden or edging perennial, used for a bright spring display. Plants form a mounding cushion of olive-green leaves, bearing masses of sweetly fragrant, small snow-white flowers for several weeks. Drought tolerant once established. These require good drainage, particularly in the winter months. Shear plants lightly after blooming to maintain a bushy, compact habit. It is semi-evergreen in our area.
A Northern Sunset perennial, it prefers average, well-drained soil in full sun.
