About
Trillium chloropetalum is a perennial herbaceous woodland plant valued for its spring-scented flower. It prefers partial shade to full shade and thrives in rich, moist, well-drained loamy soil with an acidic to neutral reaction.

In the garden
Trillium chloropetalum belongs to the genus Trillium (family Melanthiaceae) and is native to California in the USA. As a perennial herbaceous plant it is adapted to shaded, woodland conditions and produces its fragrant flower in spring, specifically April to May. Give it a sheltered, shady spot: north- or east-facing aspects suit it best. Soil should be rich, loamy and retain moisture without becoming waterlogged; an acidic to neutral pH is preferred. Avoid exposed, sunny sites. Keep soil consistently moist during the growth period, and choose a site protected from drying winds or reflected heat. In a UK garden it works well beneath deciduous trees, at the shaded edge of a shrub border, or in a dedicated shade garden where naturalising is required. It is especially appropriate where spring fragrance can be appreciated close to a path or seating area. Plant in groups to recreate a woodland understory effect and allow foliage to die back naturally once the season ends. Position plants where the scented spring flowers can be enjoyed at close range.
