Cultivation details

Succeeds in a sunny position in ordinary garden soil[1, 200] but prefers a fertile humus-rich well-drained soil[164, 200]. The soil must not be allowed to dry out in the growing season[1]. Requires a position sheltered from cold drying winds[1, 200]. A very ornamental plant[1]. This species is almost certainly not hardy outdoors in Britain[200]. Flowers are produced on the current seasons growth[200].

Plant Propagation

Seed - best sown as soon as possible in a greenhouse. Germination can be erratic but usually takes place within 20 - 60 days at 20°c[164]. When large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out in late spring or early summer after the last expected frosts. Root cuttings, 6 - 8cm long, December in a greenhouse. High percentage[78]. Division of suckers in the dormant season. Very easy, they can be planted out direct into their permanent positions if required.
