Flowers
The plant flowers in late summer. The purple flowers have yellow markings which may assist in attracting bees for pollination.[10] Two species known to pollinate the flowers are Melissodes apicatus and Dufourea novaeangliae.[11][12] Once the plant begins to produce seeds, the stem supporting the inflorescence bends to submerge the fruits and seeds.[7] Seeds are dormant at the time of dispersal and will not germinate without stratification for 6–8 weeks.[9]
The flowers of the species are
Cultivation
This plant is cultivated as an ornamental garden pond plant, and has gained the Royal Horticultural Society's Award of Garden Merit.[14][15]
Uses
The young leafstalks can be eaten raw (with the unripe fruits stripped off) or cooked. The seeds are edible raw, and can be ground into grain.[16][17]
