Its flower has three brown to maroon petals that are typically under 3 centimetres long. The petals are recurved, with tips converging over the stamens. The fruit has 6 well developed ridges. The seeds have an oil-rich structure called an elaiosome, which promotes dispersal by ants and other foraging insects.
Status
"Trillium recurvatum" is common throughout much of its range. It is not considered to be globally threatened, and its status is considered secure. However, it is monitored by conservation agencies in several states at the edge of its range, where it becomes rare. For example, in Wisconsin it is considered rare or uncommon and therefore a species of special concern. In Michigan, it is considered a state threatened species and is protected by law.References:
