Aubrieta is a genus of about 20 species of flowering plants in the cabbage family Brassicaceae. Aubrieta originates from southern Europe east to central Asia but is now a common garden escape throughout Europe. It is a low, spreading plant, hardy, evergreen and perennial, it thrives best when planted in well-draining, alkaline soil in a full sun location. In midsummer the foliage tends to die back and will benefit from a hard shearing. As a member of the mustard family, this is a tough plant that requires little care. Once established, it has a good tolerance for drought. Aubrieta plants shine in full sun, but will also grow in part shade. For best results, grow plants where they will receive at least a half-day of sun. Plants that grow in too much shade will lose their compact, mounded appearance, take on a leggy look, and have sparse flowers. Aubrieta plants need a moderate amount of water, but they don't like wet feet. Rocky soils that prevent standing water will keep healthy root systems.
