Arrow Arum is an aquatic plant with large, thick leaves that grow one to two feet long. Leaves are shaped like an arrowhead. This plant is often confused with other arrowhead-shaped water plants, such as Arrowhead and Pickerelweed.

Arrow Arum (pronounce "air - um"), grows in shallow water in ponds, lakes, slow-moving rivers, and marshes.

It is a perennial, so it grows back every year.

Arrow Arum blooms from May to July. Flowers grow on a large spike, called a spathe. The spathe is 4 - 7 inches long with many tiny yellow-green flowers on it.

The fruits of this plant are blackish-green berries which grow in clusters the size of chicken eggs. When the fruits are ripe, they get heavy. The stalk they grow on will bend over with the weight, and the Arrow Arum will actually plant itself in the mud.

Arrow Arum grows in large colonies. It has large underground stems, called rhizomes, which grow sideways and send up new plants. Colonies can survive in bright sun or shade.

Arrow Arum often has to compete with colonies of other aquatic plants, like cattails, reeds, arrowheads, Lizard's Tail, lilies, Pickerelweed, and bulrushes.

The seeds of Arrow Arum are eaten by Wood Ducks and other animals. Flowers are pollinated by bees and other insects.

Arrow Arum provides great shelter and cover for both small and large animals that move in, or near, the water, including: deer, beaver, muskrat, snakes, turtles, frogs, dragonflies, fish, and many others.
