- Description
-
Prairie trillium is an herbaceous perennial wildflower in the trillium family (Melanthiaceae). It is found in forest and woodland areas in the central and eastern U.S., including NC, where it is a NC Significantly Rare species. Several forms have been described, but these are no longer given taxonomic recognition. The epithet means “recurved” and likely describes the three sepals, which bend backward and point toward the soil.
Plant in humus-rich moist soils in part shade to dappled sunlight in a woodland setting. They can be naturalized under trees.
The maroon, three-petaled, sessile flowers appear above the mottled bracts in spring. The plant can take up to 10 years to bloom and usually go dormant by mid-summer. They slowly spread by rhizomes to form colonies. The red color of the flowers may attract carrion beetles and flies. This species is a larval host plant for the black-patched clepsis moth (Clepsis melaleucanus) and American angle shades moth (Euplexia benesimilis). Small mammals enjoy the fruits as a food source. Ants are attracted to the seeds, which they carry to their nests.
Prairie trillium is well suited to woodland, native plant or shady pollinator gardens.
Insects, Diseases, and Other Plant Problems: No serious problems. Slugs and snails are occasional pests and leaf spot, rust and smut are occasional disease problems. It does not transplant well.
