Growth—

Plants are hardy to about -25°c[1]. Succeeds in most good garden soils[2], preferring one that is well-drained and moisture retentive[3]. Prefers a sunny position[3], but it also succeeds in partial shade[4]. Prefers a rich soil[2], but tolerates poor ones[4]. A polymorphic species, there are many named varieties selected for their ornamental value[3]. Hybridizes freely with other members of this genus[3]. Plants need to be divided every few years, preferably in the spring, in order to keep the plant vigorous[1]. Most species in this genus seem to be immune to the predations of rabbits[4]. Attracts butterflies and moths, it is also a good bee plant providing nectar in autumn[5].

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[6]. Germination usually takes place within 2 weeks at 20°c[6]. When large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. Division in spring or autumn[3]. Very easy, larger divisions can be planted straight into their permanent positions whist smaller clumps are best potted up and kept in a cold frame until they are growing away well. Basal cuttings in late spring. Harvest the shoots when they are about 10 - 15cm long with plenty of underground stem. Pot them up into individual pots and keep them in light shade in a cold frame or greenhouse until they are rooting well. Plant them out in the summer.
