- Description
-
Sweet Betsy is an herbaceous perennial wildflower native to the piedmont and mountains of North Carolina and the southeastern USA. It is a member of the trillium family (Melanthiaceae). It can be found in rich soils of woodlands, moist slopes, and bottomlands. The species epithet means “wedge-shaped” and refers to the shape of the petals.
It is one of the largest and most vigorous of the sessile trilliums (those with no pedicel between the bracts and the flower). The plant spreads by underground rhizomes. It has three bracts that are large and mottled. The flowers have three sepals and three petals that are usually maroon, but some plants produced greenish yellow flowers. The blossoms have a foul odor, which attracts flies. The seeds attract ants, which carry them to their nests. It is the larval host plant for the black-patched clepsis moth (Clepsis melaleucanus) and American angle shades moth (Euplexia benesimilis).
Grow this plant in moist well-drained humus-rich soils in part to full shade. Use in a shady or woodland garden.
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.
