Water Arum is an aquatic perennial with a spadix of tiny flowers surrounded by a spathe, typically mistaken for a single flower. The heart-shaped leaves are glossy and arise on long stalks directly from the rhizome. Their dark green appearance contrasts with the more flamboyant spathes, which bloom in the summer. Fruits emerge after flowering, bearing red berries. The plant flourishes in shallow water, up to 6 inches (15 cm) deep, and spreads to form dense colonies.
