Trillium cuneatum, the little sweet Betsy,[3] also known as whip-poor-will flower, large toadshade, purple toadshade, and bloody butcher,[4] 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.[5] 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.[6]
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 50–400 m (160–1,310 ft)[4] 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.[7]
A few scattered populations of Trillium cuneatum can be found in Michigan and other more northern states,[6][8] 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.[9]
