Dimpled Trout Lily

Erythronium umbilicatum (er-ih-THROH-nee-um um-bil-ih-KAY-tum)

Family: Liliaceae Native Groundcover (<1 ft)

Dimpled Trout Lily is a native spring ephemeral found in moist bottomland or slope forests, or in rather dry upland habitats throughout NC and the southeastern U.S.A. Two fleshy mottled leaves appear in early spring with a single stem bearing one yellow lily-like flower. The plant then dies down by summer. It grows from a small white pointed bulb that multiplies and can form colonies. The bulbs are often deep and it is difficult to dig them up without damaging the plant. Use this plant in a woodland setting with humus enriched moist soils in partial shade to shade. They will do well along a waterway as ponds or streams.
