White Erect Trillium

Trillium erectum (TRILL-lee-um ee-REK-tum AL-bum)

Family: Melanthiaceae Native Herbaceous (1-3 ft)

White wakerobin is an herbaceous perennial wildflower native to the mountains of NC and TN. It tends to occur in drier habitats and is typically found on acid soils, in open dry or rich mesic woods, within laurel and rhododendron thickets at mid to high elevations. It is a member of the trillium family (Melanthiaceae). The varietal epithet is Latin for white. The white three-petaled flower appears in spring and has a dark purplish ovary in the center. The bracts are green and occur in a whorl on the stem. Pollen and nectar of the flowers attract bees, yellow jackets and other pollinating insects. White wakerobin is the larval host plant for the black-patched clepsis moth ( Clepsis melaleucanus ) and American angle shades moth ( Euplexia benesimilis). Small mammals and ants enjoy the seeds and fruits as a food source. Use in a woodland setting for naturalizing. They will spread by rhizomes to form a clump. 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.
