Propagation

Seed - sow spring in a greenhouse. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.

If you have sufficient seed it might be worthwhile trying a sowing in mid to late spring in situ outdoors[4]. Cuttings of soft wood from the base of the plant, June/July in a frame. Basal cuttings in spring[5]. 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.

Division in spring or autumn[4]. This needs to be done fairly regularly because the clumps soon become congested[6]. Very easy, larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.

Cultivation

Grows well in ordinary garden soil[7][4], succeeding in most conditions other than boggy soils[6]. It prefers a fertile moisture retentive soil[5] in a sunny position[8][4]. Dislikes dry soil[5].

Plants seem to be immune to the predations of rabbits[6]. A good bee and butterfly plant[9].

A very ornamental plant[7], some named forms have been selected for their ornamental value[10].
