Perennial Cultivation: Snowcap Rock Cress is also a low growing mat forming perennial that makes an excellent groundcover when grown on slopes, in beds, or in rock gardens. Once established Snowcap Rock Cress will cover itself with small white fragrant flowers in early spring. From a distance it looks like snow.

Plant Snowcap Rock Cress in full sun in well drained soil. Soils that drain well are important to successfully growing Snowcap. It tolerates poor soils, and hot dry conditions fairly well.

Propagation:
Seed can be started in a cold frame but for quicker growth, visit your local garden center and purchase pre-started plants. Space new container grown plants 8" - 12" apart depending on how quickly you wish the area to fill in. Plants can be dug and divided in the spring, or divide Snowcap Rock Cress plants every three years during the fall to help maintain plant vigor.

Potential pests ~ diseases:
Aphids or mildew.
