Cultivation Details
The plant grows wild in moist, loamy soils, full sun to partial shade in riparian and forest edge habitats[1]. Prefers a neutral to slightly acidic soil[1]. The plant can spread freely by means of stolons and may need regular thinning in order to control its spread[1].
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[2]. Germination usually takes place within 2 weeks at 20°c[2]. 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.
