Trillium cuneatum
Trillium cuneatum, the little sweet Betsy, also known as whip-poor-will flower, large toadshade, purple toadshade, and bloody butcher, is a species of flowering plant in the family Melanthiaceae. It is native to the southeastern United States but is especially common in a region that extends from southern Kentucky through central Tennessee to northern Alabama. In its native habitat, this perennial plant flowers from early March to late April (depending on latitude). It is the largest of the eastern sessile trilliums.

Trillium cuneatum prefers to grow in rich soils in mostly upland woods, especially limestone soils but also at less calcareous sites. It is found at elevations of  and has three broad, mottled leaves surrounding a sessile, banana-scented flower. The petals are erect and either maroon, bronze, green, or yellow in color.

A few scattered populations of Trillium cuneatum can be found in Michigan and other more northern states, presumably due to anthropogenic effects. More recently, there have been dozens of citizen science observations in the eastern United States from Washington, D.C. to New York City.
