About
Trillium erectum, the red trillium, also known as wake robin, purple trillium, bethroot, or stinking benjamin, is a species of flowering plant in the family Melanthiaceae. The plant takes its common name "wake robin" by analogy with the European robin, which has a red breast heralding spring. Likewise Trillium erectum is a spring ephemeral plant whose life-cycle is synchronized with that of the forests in which it lives. It is native to the eastern United States and eastern Canada from northern Georgia to Quebec and New Brunswick.

Uses
The root of the red trillium was used by various indigenous peoples of North America as an aid in childbirth, hence the common name birthwort or birthroot (which is sometimes corrupted to bethroot). Root tea was used for menstrual disorders, to induce childbirth, and to aid in labor. The Cherokee peoples used a poultice of the whole plant to treat tumors, inflammation, and ulcers.
