A moist fertile soil is essential in a sunny or partially shaded position. It can also be grown along the damp margins of ponds and streams. It will tolerate water levels up to 30cm deep if potted up into a basket with aquatic compost. Protect the crown of the plant during winter with a thick, dry mulch, such as straw. Divide large clumps of plants every second year in spring.
