Liliaceae (Lily Family)

USDA Symbol: TRSE2
USDA Native Status: L48 (N)
A thick rhizome sends up a 4-12 in. stem with three broadly oval leaves at the apex. Flower sepals are spreading and green while the petals are ascending and deep-maroon. The petals elongate slightly as the flower ages and gradually turn yellowish green. The stalkless flower is directly above the 3 whorled leaves and appears closed, an impression created by its narrow, erect petals.
The flower somewhat resembles Purple Trillium (T. erectum) but is distinguished by its lack of stalk and closed appearance. Several other stalkless species that appear closed are Little Sweet Betsy (T. cuneatum), an ill-scented southeastern species with large flowers up to 3" (7.5 cm) long and weakly mottled leaves; Yellow Trillium (T. luteum), in southern and midwestern areas, with yellow, lemon-scented flowers and mottled leaves; Green Wake-Robin (T. viride), also in southern and midwestern areas, with narrow, greenish, clawed petals up to 2" (5 cm) long; and Prairie Trillium (T. recurvatum), a midwestern plant with erect, clawed, maroon petals, drooping sepals, and mottled leaves.
