Stolons absent. 2n = 24.

Flowering spring. Woods of flood plains and adjacent slopes along creeks, streams, small rivers; 0--900 m; Ala., Fla., Ga., Ky., Md., N.C., S.C., Tenn., Va., W.Va.

Since subsp. umbilicatum does not produce stolons, most plants in a population produce flowers, and seedlings may be frequent. Although many Erythronium species have considerable variation in size at flowering, E. umbilicatum subsp. umbilicatum is especially variable in this regard.
