Sessile trillium is a charming native wildflower that produces distinctive three-petaled maroon flowers in early spring. This woodland perennial forms neat clumps with attractive mottled leaves and goes dormant by midsummer. It's perfect for shaded areas where few other flowering plants will thrive.
In an HOA neighborhood
Sessile Trillium takes more care to keep looking intentional in a front yard. Maintenance level: low. Consider it for backyard or mid-zone beds rather than the street edge.
Works well in: backyard only.
- Disappears completely by midsummer leaving bare spots
