Arrow arum is a native perennial plant with large, arrowhead-shaped leaves. It grows in shallow, tidal fresh waters throughout the Chesapeake Bay region.
Arrow arum has long, thick, arrowhead-shaped leaves with prominent veins down the middle and along the edge. The leaves can be up to 18 inches in length and nearly 6 inches wide. Leaves grow from the top of stalks, which grow from a thick rootstock that is embedded in the mud. A white flower spike contained in a green sheath blooms in May to July. Arrow arum grows to 3 feet tall.
Grows in shallow and slow-moving fresh waters, including marshes and swamps, on tidal flats, and along the edges of rivers and streams. Forms large, dense colonies.
Throughout the Chesapeake Bay region, including Delaware, Maryland and Virginia.
After blooming, flower spikes mature into dark, drooping pods full of large, green seeds. The pods eventually split open and release their seeds.
