Maintenance

Long-blooming.. Members of the Water-Plantain Family grow in water, in swamps, on muddy banks, or occasionally in wet sand. Good for water gardens. They should be planted no deeper that 12″ in a water garden in a full sun location. They spread easily by rhizomes and may be thinned if you have limited space. Set up a pond or a water collection tank near a downspout to supplement water.

Comments

Blooms June-November. This perennial arises from tuber-producing rhizomes. Arrowhead shaped leaf blades arise from the base. Submerged leaves are lance-shaped or even bladeless. The 3 petaled white flowers appear in late spring and summer. Attracts: tubers eaten by ducks, geese, muskrats, and nutria. Seeds are sometimes consumed by ducks. Submerged portions of all aquatic plants provide habitats for many micro and macro invertebrates. These invertebrates in turn are used as food by fish and other wildlife species (e.g. amphibians, reptiles, ducks, etc.). After aquatic plants die, their decomposition by bacteria and fungi provides food for many aquatic invertebrates.
