About this plant
Trillium erectum produces a neat whorl of three broad, pointed leaves that spread horizontally near the top of a single upright stem. At the center, a solitary flower rises above the leaves, its three maroon to deep reddish-purple petals surrounding a cluster of yellow stamens. Blooming in mid to late spring, the flower has a fleshy texture and upright form that gives the plant a distinctive presence in shaded woodland settings.
Native to eastern North America, Trillium erectum grows naturally in deciduous forests from Canada to the Appalachian region. In gardens it brings classic woodland character to shaded borders, native plantings, and naturalized areas beneath trees, where its early spring blooms provide seasonal interest among ferns and other shade-loving perennials.

Design tip
The early flowers arrive when the garden is still waking up, so give it a spot you pass often in spring. Cooler light suits it, so tuck it on the north side of a shrub or wall where the soil stays even.
