Aubrieta gracilis 'Rock On Blue' Rock On Blue Rock Cress

Rock On Blue Rock Cress (Aubrieta gracilis ‘Rock On Blue’) is a low-growing, early-blooming perennial known for its vibrant blue to blue-purple flowers that form a dense carpet in spring. This compact variety produces masses of blooms that nearly cover the evergreen foliage, creating strong visual impact in early-season gardens.

Rock On Blue forms a tight, spreading mat, making it ideal for rock gardens, borders, edging, and cascading over retaining walls. Its neat growth habit and abundant flowering make it a reliable choice for both small and large landscape plantings.

Well-suited to Alberta’s climate, aubrieta is a hardy perennial that thrives in full sun and well-drained soil. It performs especially well in Prairie conditions where drainage is excellent, providing consistent early spring colour year after year.
