Yellow trillium

Trillium luteum

TRILL-ee-um LOO-tee-um Audio

This mid- to late-spring bloomer bears yellow blossoms atop a trio of leaves often mottled with a paler shade of silvery-green. It is faintly fragrant of lemon oil, and grows to about 14 inches tall.

Noteworthy CharacteristicsMost trilliums are native to woodlands and scrub of North America. Groups of them make an elegant understory planting in a woodland or shady naturalized area. Trilliums go dormant in summer, so plant them with other shade-loving perennials to share their place until they reappear the following spring. 

CareProvide rich, moist, but well-drained soil with a neutral to acidic pH. Plant in full to part shade. Mulch annually with rich organic matter.

PropagationTrilliums propagate readily by division when plants are dormant in late summer or early fall.

ProblemsSmut, rust, fungal spots, slugs, snails
