Great white trillium

Trillium grandiflorum

TRILL-ee-um gran-dih-FLOOR-um Audio

This showy spring-blooming trillium has large white blossoms up to 3 inches long, which fade to soft pink and from cup-shaped to open and recurved. Its veined leaves are solid green, and it grows to 18 inches tall and about half as wide.

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

CareGrow in rich, moist, but well-drained soil with a neutral to acidic pH. Plant in part to full shade and provide an annual mulch of rich organic matter.

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

ProblemsSmut, rust, fungal spots, slugs, snails.
