Overview
Toadshade (Trillium sessile) is a spring-blooming woodland perennial in the eastern United States. Like all trilliums it grows in threes, with a whorl of three leaves topped by a single flower.
Its common name reflects the sessile (stalkless) flower that sits directly on the leaves, and the maroon, closed bloom that is thought to attract carrion-feeding pollinators with a faint scent.
The leaves are typically mottled with silver-green and bronze, adding interest even when the plant is not in flower. It emerges early, blooms, and often goes dormant by midsummer.
How to identify it
Look for:
- A whorl of three broad, often mottled leaves marked with silver, green, and maroon
- A single stalkless (sessile) flower sitting directly atop the leaves
- Three erect, narrow maroon to brownish petals that stay mostly closed
- Compact stature, usually 10 to 30 cm (4 to 12 in) tall
- Early spring emergence, often going dormant by summer
Care & growing
A rewarding but patient woodland plant.
- Light: Partial to full shade, mimicking a deciduous forest floor
- Water: Keep evenly moist during the growing season; tolerates summer dryness when dormant
- Soil: Rich, humusy, well-drained, near-neutral woodland soil
- Temperature: Hardy roughly USDA zones 4 to 8
- Feeding: A topdressing of leaf mold each fall is sufficient
- Propagation: Slow; by seed (which can take years to flower) or careful division of established rhizomes. Never collect from the wild
Habitat & origin
Native to the central and eastern United States, from the Appalachians and Midwest into the South.
It grows in rich, moist deciduous woodlands, on slopes, and along stream bottoms with deep leaf litter. In cultivation it is prized for shade and native woodland gardens.
Frequently asked questions
Why doesn't the flower open up?
Toadshade's maroon petals naturally stay erect and mostly closed. The flower relies on scent rather than showy display to attract beetle and fly pollinators.
What does 'sessile' mean here?
It means stalkless. Both the flower and the leaves sit directly on the stem with no individual stalks, which distinguishes it from nodding or stalked trilliums.
Can I pick the flowers?
It is best not to. Picking the leaf whorl can starve the rhizome and set the plant back for years, and many trilliums are legally protected.
Why does it disappear in summer?
It is a spring ephemeral. After blooming and storing energy, it often goes dormant and dies back underground until the next spring.
