Growth—

Species in this genus are generally easily grown in ordinary well-drained soil[1]. This species of rockcress is considered an important first brood nectar plant for 'Karner Blue' butterfly (Lycaeides melissa samuelis Nabokov), an endangered species in North America.

Propagation

Seed - it is best to surface sow the seed as soon as it is ripe in a light position in a cold frame[2]. Seed can also be sown in spring. It usually germinates in 2 - 3 weeks at 21°c[2]. When large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. Division after flowering[3]. Very easy, the divisions can be planted out straight into their permanent positions if required. Cuttings in a shady border in summer[1].
