- Description
-
Large-flowered trillium is an herbaceous perennial wildflower in the trillium family (Melanthiaceae). It is native to a wide area of eastern North America, including the piedmont and mountains of North Carolina, in rich forests and mesic slopes. The species epithet is Latin for “large-flowered.”
Plant in part to full shade in humus-rich, well-drained soils.
The flowers are among the largest and showiest of the trilliums with flowers being 2 to 4 inches across and held above the large bracts that are glossy and green. This species is the larval host plant for the black-patched clepsis moth (Clepsis melaleucanus) and American angle shades moth (Euplexia benesimilis). The flowers' nectar attracts early-emerging native bees and honeybees. In areas where the plant is abundant, the large leaves provide cover for small mammals.
Large-flowered trillium looks great in mass plantings in woodland settings. It spreads slowly by rhizomes.
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.
