Arrow Arum (Peltandra virginica)

Arrow arum is found in freshwater wetlands throughout the southeast; and on the refuge, you'll spot this plant at the water's edge along the Wildlife Loop on the side closest the visitor center (map).

Arrow arum, a perennial, is also known as duck corn because wood ducks often include the plant's seeds in their diet. Because the seeds contain crystals of calcium oxalate, most marsh birds (other than wood ducks) do not like them.

The seeds develop in a spike-shaped pod and are released early in the fall as the pod decays. The arrow arum leaves can grow up to three feet in length, and plants as high as seven feet have been found.
