$0.00

DESCRIPTION
Aubrieta deltoidea, commonly known as Rock Cress, is an attractive perennial plant that forms a low-growing mat of colorful flowers in early spring, originating from Europe and western Asia. The plant has small, oval-shaped, gray-green leaves that are hairy to the touch. Its most striking feature is its profusion of small, four-petaled flowers that bloom in shades of purple, pink, blue, and occasionally white or red, creating a vibrant carpet of color. Ideal for rock gardens or as a ground cover, Rock Cress thrives in full sun to partial shade and requires moderate watering, avoiding overwatering to prevent root rot. It attracts bees and butterflies, adding a delightful touch of nature to any garden. Maintenance is minimal, with occasional pruning after flowering to maintain a neat shape and promote new growth. With its resilience and beauty, Rock Cress is a delightful addition to the early spring landscape.
