This plant is a perennial plant that is a rising plant that shapes into groups of basal leaves that are formed on stout petioles. The basal leaves are upward and they are 8-24" long and 4-10" across. They hesitate and sagittate and the basal lobes are pointed in shape. This plant is smooth along the ends, pinnate veined that is a darkish green color, smooth and hairless. The stout on the basal leaves is a lighter green color they are about 12 to 30 inches long and are also very smooth and hairless.
These leaves tend to shed its leaves in Illinois as well as other areas in the North but in the areas in the Gulf coast, they are always green throughout the year. The small flowers on this plant are positioned along a cylinder spike that is neighbored by a narrow spathe that is 4 to 8 inches long. The spathe is a lightish green color and is smooth and hairless while tapering slowly on both of the ends, it also has a white and green margin and stays open at the center. The spadix can be white, cream or even a pale yellow. Arrow Arum plants have both male and female reproductive organs. The female ones are located at the end of a spadix and the male flowers are located on the top. All of the male flowers have 4 to 5 stamens and the females ones have a single-celled ovary with a short type. Neither of the male or females has petals or sepals. The stout peduncle of the spadix is 8 to 28 inches long and is a lighter green and smooth. This plant blooms in the late Spring and in the early Summer time for only about 2 to 3 weeks. After this occurs the lower part of the spadix grows an ovoid group of berries and all of the other parts of the spadix rots away. Once the berries start to grow and mature, the peduncle starts to bend downward which inserts the berries into the waters.
