Uvularia grandiflora — large-flowered bellwort

Copyright: various copyright holders. To reuse an image, please click it to see who you will need to contact.

Facts

Large-flowered bellwort is distributed in rich, moist, deciduous forests in western New England. Deer favor the foliage as browse, and consequently it tends to decline in areas with an overpopulation of deer. The Potawatomi made a salve out of the root to treat sore muscles, tendons and backaches.
