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. The leaves have prominent veins down the middle and along the edge. They 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.
Reproduction and Life Cycle
After blooming, flower spikes mature into dark, drooping pods full of large, green seeds. The pods eventually split open and release their seeds.
