Cultivation & Habitat

Seed – best sown as soon as it is ripe in a cold frame in late summer[200]. Stand the pots in 2 – 3cm of water to keep the soil wet. The seed usually germinates in 1 – 3 months at 15¡c[138]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in a tray of water in a cold frame until they are at least 15cm tall. Plant them out into their permanent positions in the summer. Division in early spring or autumn[200]. 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 summer or following spring.
A plant of boggy soils and shallow pond margins[1], it requires a deep rich slightly acidic soil[200]. It grows well in heavy clay soils. It has slender floating or creeping stems that root at the nodes to form new plants[235]. A greedy plant, inhibiting the growth of nearby plants, especially legumes[54].
North-western N. America – Alaska to Canada. E. Asia – N. China, Mongolia, Siberia.
