Physical Characteristics

Perennial growing to 0.15m. It is hardy to zone 7. It is in flower from May to June. The flowers are monoecious (individual flowers are either male or female, but both sexes can be found on the same plant). We rate it 2/5 for edibility and 0/5 for medicinal use.

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils. The plant prefers acid and neutral soils. It cannot grow in the shade. It requires wet soil and can grow in water.

Habitats and Possible Locations

Pond, Bog Garden.

Edible Uses

Fruit; Root.

Root - must be well cooked in order to destroy an acrimonious principle, see the notes above on toxicity[95]. The root contains much farinaceous material[1, 105, 161] and can weigh up to 2.7 kilos each[95].
Fruit[105]. No more details but caution is advised - see the notes above on toxicity.

Cultivation details

Requires a wet lime-free humus-rich soil by the side of water or in shallow still or slowly flowing water in a sunny position[200].
Plants are best grown in clumps[1].

Propagation

Seed - best sown as soon as it is ripe in late summer in pots of soil that are submerged to their rims in water[200]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in trays of 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 in spring[200]. 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.
Stem cuttings rooted in wet mud in the summer[200].
