Liliaceae (Lily Family)
USDA Symbol: TRGR4
This largest and showiest trillium is frequently cultivated in wildflower gardens. The underground rootstalks were gathered and chewed by Native Americans for a variety of medicinal purposes. This practice may have been fatal to the plant, since these trilliums arise from the rootstalks, which often die if the leaves are removed.
