Bashful Trillium

Trillium catesbaei (TRIL-ee-um KAYTS-bee-eye)

Family: Melanthiaceae Native Herbaceous (1-3 ft)

Catesby's trillium is an herbaceous perennial wildflower in the trillium family (Melanthiaceae) native to the Southeastern USA, including North Carolina. In nature, it can be commonly found in bottomland forests, mesic slopes, and cove forests and is common in the NC Piedmont, and rarer in the mountains and coastal areas. The species epithet honors Mark Catesby, the English naturalist who published Natural History of Carolina, Florida and the Bahama Islands in the first half of the 18th century. This trillium tolerates drier, warmer conditions than other trilliums and is found in acidic soils, often with rhododendrons. Plant in humus-rich well-drained soils in part shade to full shade. The Catesby's Trillium flowers face downward on a curved stem with 3 pink to purple or white recurved petals and 3 green bracts. It is the larval host plant the black-patched clepsis moth ( Clepsis melaleucanus ) and American angle shades moth ( Euplexia benesimilis ). 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.
