These colorful flowering plants will bring color to the garden and are commonly known as Rock-cress.
They are interesting in that they are related to Cabbages, however they are a low growing matt forming perennial best suited to the rock garden.
Grown for the flowers, usually a purple, that cover the plant from spring through summer. Also known as the lilac bush and rainbow rock cress, this is a plant that looks great when planted so that it can hang down over a low retaining wall.
The common form is Aubrieta deltoides, and is originally from southern Europe and likes a wet winter in a well drained soil and a warm summer. It is called rock cress because it naturally grows on rocky outcrops.
Grows well in a humus rich soil in full sun to part shade. Can be grown from seed, and also grows well in containers. Best suited to zones 4 – 9.
Best suited to areas that have a distinct winter, rather than sub tropical climates. Provide water during summer months, but do not over water and allow to dry out between watering.
