Propagation

Seed - best sown as soon as it is ripe in pots standing in 2cm of water in a cold frame. Cover the seed lightly with silver sand. Submerse in 3cm depth of water after the seedlings emerge[7]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in water 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. Division is best in April but it can be done at almost any time of the year[1]. Very easy, larger divisions can be planted out direct into their permanent positions. We have found that it is better to pot up the smaller divisions and grow them on in light shade in a cold frame until they are well established before planting them out in late spring or early summer. Lateral shoots.
Cultivation

A water or bog garden plant, it requires a rich soil[11] and prefers growing in water 15 - 30 cm deep[1]. Plants are hardy to about -25°c[6]. A very ornamental plant, it forms spreading patches by means of a thick creeping rhizome[6]. There is a species of bee (Dufourea novae-angliae) which visits this plant for nectar and pollen and does not visit any other species of plant[2].
