Propagation

Seed - surface sow in spring in a cold frame. Do not allow the compost to become dry. Pre-chilling the seed for two weeks can improve germination rates^[3]. Germination usually takes place within 2 weeks at 20°c^[3]. When large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. Division in spring or autumn^[5].

Cultivation

Succeeds in most good garden soils^[1], preferring one that is well-drained and moisture retentive^[5]. Prefers a sunny position^[5]. Most species in this genus seem to be immune to the predations of rabbits^[6]. Hybridizes freely with other members of this genus^[5].
