Rock Cress Seeds
A fast-growing, hardy perennial, Rock Cress is a popular choice for homeowners who want to add vibrant color to their yard. Rock Cress gets its name from its ability to grow on rocky cliffs and stone walls, and is commonly used in small gardens, along borders, and as ground cover for landscaping projects. Boasting beautiful green foliage for most of the year, the plant produces dazzling pink, purple, and white blossoms in Spring. Rock Cress is often referred to as Arabis or Aubrieta, two of the most common types of the plant.
Why Plant Rock Cress Seed
Compact and low-growing, Rock Cress forms a dense, ornamental cover that adds variety, texture, and fragrance to yards and gardens. Rock cress seeds perform especially well in small spaces such as planters and container gardens, with some of the most popular varieties including Red Sensation, Hendersonii, Whitewall Gem, and Cascade Blue. In addition to providing long-lasting beauty, Rock Cress supports pollinators by providing nectar and pollen for bees and butterflies.
How to Grow Rock Cress From Seed
Plant Rock Cress in the early spring or fall, sowing the seeds in well-drained soil spaced about 15 to 18 inches apart to allow for spreading. Press the seeds into the soil, but do not cover them. Be sure the planting area receives plenty of sunlight. Water new Rock Cress plants every few days for the first 3 weeks to help roots grow. Once established, Rock Cress is very drought-tolerant, requiring watering only every 10 to 14 days.
