A.k.a. wapato and broadleaf arrowhead. A vigorous wetland species with showy white flowers, well suited to bank naturalization and stabilization. Prefers slow moving or still water, but can grow in consistently saturated wetland (or bog-like) soils.
Light: Full Sun
Soil Moisture: Wet
Soil Type: Muck, Standing Water
Bloom Color: White
Bloom Time: Jul-Sep
Root Type: Rhizome
Notable Wildlife Interactions: Flowers attract a number of pollinators including bees, flies, skippers, and beetles. Hosts a number of small insects including the obscure pondweed moth. Seeds, foliage, and tubers are eaten by wetland animals such as ducks, muskrat, and aquatic turtles.
Notes: Tubers were commonly eaten in many Native American cultures. Unfortunately, since aquatic plants concentrate pollution in their tissues as they filter polluted water, arrowheads brown in uncontrolled conditions should not be consumed.
