Purple trillium is a common spring wildflower found throughout most the state in moist and mixed forests. This plant doesn't have true leaves; instead, it features leaf-like bracts arranged in a whorl of three at the top of the stem (not a true stem but a scape). Both the roots and leaves emit an acrid odor. The solitary flower on a long (up to 3″) peduncle arises above the leaves. The flowers, which have three petals and three sepals, are known for their particularly foul smell, earning the common name "stinking Benjamin".  While the petals are typically maroon, they can occasionally be white or yellow-green. The plant's faint fetid odor and maroon petals attract carrion flies, which are the primary pollinators of this trillium.

Grows in moist, shady woods & stream floodplains with rich soil.  Prefers light shade or dappled sunlight.

Present throughout the state, except a few counties in the south-central part of the state. See distribution map at BONAP.

Range: Nova Scotia, Quebec, Ontario south through eastern and central US.

Purple trillium has been traditionally used as a folk remedy for bleeding, skin irritations, and snakebites. A tea made from its rhizomes and roots was commonly given to new mothers after childbirth to help reduce bleeding.

Deer browse on the leaves.  Certain insects such as carrion flies are attracted by the color and fetid smell of the flowers and are the main pollinators of the plant.
