20 - 25 cm
violet - lavender

well drained, gritty
acid - neutral - alkaline
The genus Aubrieta belongs to the cabbage family, Brassicaceae, native to S-Europe and Central-Asia. It's a small genus of similar mat forming species with relatively large flowers. They grow best in gritty soil in full sun.
Basal cuttings in spring or early summer.
A stalk without buds is torn off at the base and planted in soil mixed with pumice and kept in a sheltered spot out of strong sunlight until the cutting is rooted.
Seed sown in March.
Seed just covered and kept at 20°C (68°F) until germination. After germination it should be kept at a lower temperature with plenty of light so the plants won't become lanky.
Beautiful rock garden plant, but unfortunately tender. Can survive given sharp drainage.
