Arrow Arum is a perennial wetland plant native to eastern North America. It is found in shady swamps, shallow slow moving rivers, edges of ponds and lakes, and other depressions. Arrow Arum is in the Araceae family which includes plants with unique flowers. The flower consists of a spathe and spadix. The spathe is the little hood that you see in the above photo, and the spadix is the long tubular part inside of the spathe. Other common plants in this family are water arum, skunk cabbage, and jack in the pulpit. The look alike plant arrowhead can be distinguished by having palmate venation as opposed to pinnate venation seen in arrow arum. In arrow arum there are three wide veins in the leaf as opposed to arrowhead which has many. Also, the flowers are completely different because arrow arum has a flower with a spathe and spadix and arrowhead has a long stem of small three-petaled white flowers
