Some rockery perennials, such as Cerastium, Arabis and Aubrietia, can become too dominant in the rockery. Draba suffers from the opposite problem – its small cushion of foliage can be overlooked in a large rock garden. It is a plant to grow in the crevices between stones and in trough gardens. Choose with care when buying – many species are not suitable for growing outdoors.
VARIETIES: The easiest one to grow is the largest – D. aizoides. The basic details are height 4 in., spread 6 in.
Flowering period: April. The greyishare borne in tight rosettes and the VA in. yellow are carried in clusters. The choicest variety is the tiny D. bryoides imbricata, with a height and spread of only 2 in. The bright yellow flowers appear on short wiry in April – a plant for the sink garden or small rockery.
SITE AND SOIL: Any well-drained soil – thrives best in full sun.
PROPAGATION: Sowunder glass in spring or plant rosettes as in a cold frame in summer.
