Giant trillium

Trillium chloropetalum

TRILL-ee-um klor-oh-PET-ah-lum Audio

This species blooms in early to mid-spring with large blossoms of white, yellow, or deep purple-black. It is vigorous, growing to almost 18 inches tall and wide, with leaves (usually mottled) up to 8 inches long.

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 the reappear the following spring. 

CareProvide rich, moist, but well-drained soil with a neutral to acidic pH. Plant in part to full shade and provide trilliums with 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.
