Summary

Trientalis latifolia is a shade-loving perennial native to western North America, growing from a tuber to form small colonies. Stems reach about 10–25 cm tall and bear a whorl of elliptic leaves at the apex, with 1–5 pink to pinkish-lavender or white star-shaped flowers on slender pedicels above the leaves in spring.

In cultivation, it prefers part shade to shade and loose, organic, acidic soil with regular weekly watering, and flowering occurs from April to June before a summer dormancy; propagation is primarily by tubers, with seeds also possible, and the plant spreads to form self-sustaining colonies, making a low spreading groundcover for woodland or shaded gardens, including container plantings; hardy in USDA zones 3–7.
