Trillium sessile, commonly known as Toad Trillium, is a native perennial found in rich, moist woodlands and shaded areas throughout Illinois. It thrives in well-drained, humus-rich soils and prefers partial to full shade.
This plant features large, broad, dark green leaves with a distinctive mottled pattern and a single, dark maroon or reddish-purple flower that blooms in early spring. Unlike other trilliums, the flower of Trillium sessile lacks a prominent stalk, making it "sessile" (directly attached to the leaves). The plant's flowers attract early-season pollinators such as ants and bees.
For Illinois native plant enthusiasts, Trillium sessile is a striking woodland species that adds elegance to shaded gardens, offering seasonal interest and supporting local ecosystems.
