About this seed
Why gardeners choose this variety
Blue rock cress (Aubrieta deltoidea) is a low-growing perennial that forms spreading mats of small leaves and blue to violet flowers. Plants typically reach 4-6 inches high and spread along rock-garden edges or over low walls.
Its main flowering season is spring, sometimes extending into early summer depending on local conditions. It should not be expected to flower continuously through summer and autumn. A mature spread usually develops over 1-2 years.
Choose full sun and well-drained soil. Sow with a light covering of seed compost at about 65 F (18 C); germination typically takes 14-21 days. Space young plants about 12 inches apart. Trim lightly after flowering to keep growth compact and avoid wet, poorly drained winter conditions.
