DescriptionThis perennial wildflower is ¾-2' tall, consisting of a single central stem and 3 widely spreading leaves at its apex. This stem is light green to purplish green, terete, and glabrous. Individual leaves are 3-8" long and similarly across; they are oval-rhombic in shape, smooth along their margins, and sessile (or nearly so). The upper leaf surface is medium green and glabrous, while the lower surface is more pale; both surfaces are glabrous. Primary veins of the leaves are parallel, while secondary veins form an interlacing network. A flowering plant produces an erect to ascending peduncle about 1½-3" long, terminating in a single nodding flower that is held above the leaves. The peduncle is light green and glabrous. The flower is about 2" across, consisting of 3 maroon petals (reddish purple), 3 light green to greenish maroon sepals, 6 stamens, and a dark maroon ovary with 3 small recurved stigmata. When the flower is open, both petals and sepals are widely spreading; they are about the same length and similar shape, although the sepals are more narrow. The petals and sepals are lanceolate to ovate in shape and glabrous. The relatively small stamens have anthers and filaments that are about the same length; the anthers have light gray to yellowish pollen. The blooming period occurs from mid- to late spring for about 2-3 weeks. The flowers often have an unpleasant scent. Afterwards, the ovary matures into a dark maroon fruit that is broadly ovoid, 6-angled, and about ½" long. This fruit contains several seeds. The root system is fibrous and rhizomatous. Clonal colonies of plants are often produced from the rhizomes.
