Trillium erectum L.
Red trillium, Stinking-Benjamin, Wakerobin, Purple trillium
Synonym(s): Trillium erectum var. album, Trillium erectum var. flavum
USDA Symbol: trer3
USDA Native Status: L48 (N), CAN (N)
Stinking-Benjamin or Wakerobin’s single whorl of diamond-shaped leaves clasp its 6-18 in. stem. Perched 1-4 in. above the leaves is a single, nodding, crimson flower with three petals curved slightly backward. The petals wither in 2-3 weeks, leaving a fleshy, berry-like fruit. The solitary, nodding flower, with an unpleasant odor, rises on a stalk above a whorl of 3 broadly ovate, diamond-shaped leaves.
This is one of the most common eastern Trilliums. Its foul smell attracts carrion flies that act as pollinators. Early herbalists used this ill-scented plant to treat gangrene, since, according to the Doctrine of Signatures, plants were used to cure the ailments they resembled. As the genus name suggests, the floral parts and leaves of these perennials are arranged in 3s or multiples of 3, typical of the Lily family. Vaseys Wakerobin (T. vaseyi), of the southern Appalachians, is larger in all respects and has pleasant-smelling flowers.
