Large-flowered Trillium is a perennial wildflower native to the piedmont and mountains of North Carolina. In nature, it can be found in rich cove forests and mesic slopes, also less typically on ridges over "rich" rock types. It spreads slowly by rhizomes.
The flowers are among the largest and showiest of the trilliums with flowers being 2-4 inches across and held above the large bracts that are glossy and green. Plant in part to full shade in humus-rich well-drained soils. Looks great mass planted in woodland settings.
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.
