Cultivation

We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors in most parts of this country. The following notes are based on the general needs of the genus. Succeeds in any wet to moisture retentive ground, pond margins and shallow water in full sun or shade.

Propagation

Seed - sow in a cold frame as soon as it is ripe in a pot standing in 3cm of water. Only just cover the seed with soil. The seed usually germinates fairly quickly. Prick out the plants when large enough to handle and plant out in their permanent positions in early summer. Division in spring. Very easy, larger divisions can be planted out direct into their permanent positions. We have found it best to pot up the smaller divisions and grow them on in a lightly shaded position in a cold frame, planting them out once they are well established in the summer.

Edible uses

Root - raw or cooked. Rich in starch. Stem. Peeled and eaten raw or cooked. Stem base - raw or cooked. Pollen. Rich in protein, it can be added to flour when making bread, cakes etc. Seed. A nutty flavour. The seed is rather small and fiddly to harvest and utilize.

Habitat

Quite shallow water from 15 - 60cm deep.

Native range

N. America - Newfoundland to Alaska, south to South Carolina, Pennsylvania, Michigan and Idaho.
