Flowering - April - May.

Habitat - Forests, shaded slopes, ravines, streambanks.

Origin - Native to the U.S.

Lookalikes - U. sessilifolia. Vegetatively the plant resembles Polygonatum biflorum and Maianthemum spp.

Other info. - This striking species is common throughout most of Missouri except in some of the prairie regions. Its broader range includes most of the U.S. Midwest and parts of Canada. This species is one of the earlier plants to bloom in the spring. The perfoliate leaves, sometimes appearing as if sewn together by the stem, differentiate this plant from its closest lookalikes listed above.

The roots and young shoots of U. grandiflora can be cooked and eaten like asparagus, and the starchy rootstocks have also been used as food. Traditionally, the plant was used to treat sore muscles, backaches, toothaches, and swelling.

This species grows well from seed and is worthy of more widespread cultivation. The genus name "Uvularia" apparently derives from the fancied resemblance of the pendent flowers to the hanging uvula at the back of throat, and this led to its use to a treatment for sore throat and other throat ailments according to the Doctrine of Signatures.
