Trillium sessile is a species of flowering plant in the bunchflower family Melanthiaceae. The specific epithet sessile means "attached without a distinct stalk",[4] an apparent reference to its stalkless flower. It is commonly known as toadshade (not to be confused with Trillium recurvatum, which is also known by that name) or toad trillium.[5][6] It is also called sessile trillium or sessile-flowered wake-robin,[2][7] however it is not the only member of the genus with a sessile flower.
Trillium sessile is endemic to the eastern half of the United States. It has the widest range of any species of sessile-flowered trillium. There are two subpopulations geographically separated by a large gap in central Illinois where the species is strangely absent.
Trillium sessile was one of three Trillium species described by the Swedish botanist Carl Linnaeus in 1753. It is a small perennial, herbaceous plant with three leaves, but unlike other sessile-flowered trilliums, the leaves are often not mottled. It has a single trimerous flower with three reddish-purple petals and six distinctive stamens that aid identification.
