This native perennial plant is 1½2½' tall. It consists of a single basal leaf and single flowering stalk. The basal leaf has a long stout petiole that is up to 2' long and erect. This petiole is pale green, glabrous, and glaucous. The basal leaf is up to 2½' long and 2' across; it divides into 5-13 leaflets that are parallel with the ground. Each leaflet is up to 8" long and 2½" across, narrowly ovate, smooth along the margins, glabrous, and dark green. The 2 terminal leaflets may be deeply cleft into 2 or 3 lobes that resemble smaller leaflets. The naked flowering stalk is about ½1' tall (not including the flower); it is whitish green, unbranched, erect, and hairless. At the apex of this stalk is a single flower that consists of a spathe and spadix. The spathe is about 2" long, pale green, glabrous, and glaucous. This spathe wraps around the base of the spadix, but it is partially open and pointed at the top. The spadix is about 6-12" long. The lower portion of the spadix is about 2" long and nearly surrounded by the spathe; it is cylindrical in shape and bears the male and/or female flowers. Most plants are monoecious with separate male and female flowers, but sometimes they are unisexual. The male flowers occur above the female flowers; they are both rather small and inconspicuous. The upper portion of the spadix is about 4-10" long and tapers gradually to a point. It is usually whitish green and remains more or less erect. The blooming period occurs during late spring and early summer and the flowers remain attractive for about a month. They may release a fungus-like scent that is not detectable by the human nose. Each flower is replaced by an ovoid mass of berries, which become orange-red by the end of the summer. The root system consists of a corm with secondary roots. This plant can spread by forming offsets or by reseeding itself.
