How it is grown
Succeeds in most good garden soils, preferring one that is well-drained and moisture retentive. Prefers a sunny position. Most species in this genus seem to be immune to the predations of rabbits. Hybridizes freely with other members of this genus.
Propagating it: 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. Germination usually takes place within 2 weeks at 20°c. When large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. Division in spring or autumn.
