Description

Alisma subcordatum has bright-green, lance-shaped, veined basal leaves that grow on 6" stalks. Plants produce an erect, 3' to 4' tall multi-branched stem. Each branchlet is terminated by a small white or pinkish flower.

Cultivation

American water plantain is an emergent species, meaning it requires regular to permanent inundation to thrive. It typically grows in standing or slow moving freshwater, in mucky, sometimes sandy soil, and in full sun. It will slowly form a colony via its corm-like roots. It will also spread from seeds, but only under ideal conditions. An ideal plant for small ponds or water gardens where its non aggressive habit will make virtually carefree. It enjoys a broad native distribution, and bloom times will vary according to geographic location, from June to October. Zones 3-8

Propagation

Easy to propagated by dividing the clumps and separating the corms. Can be propagated from seed following strict protocols...a much more difficult proposition.

Additional Notes

The tuberous, corm-like starchy roots are edible.
