About Uvularia perfoliata L.
Uvularia perfoliata has a smooth, slender stem that grows 15 to 50 centimeters tall and forks above its middle. Its leaves are obovate, measuring 4 to 12 centimeters long and 1.5 to 4 centimeters wide. They are glabrous or glaucous, and perfoliate, with usually 1 to 4 leaves growing below the stem's fork. Each stem bears a single downward-drooping flower, with six tepals 2 to 3.5 centimeters long that are granular on the inside. Its fruit is a triangular, three-lobed capsule 7 to 13 millimeters in length.
Uvularia perfoliata is widely distributed across the eastern and southern United States, ranging from Texas to New Hampshire, and also occurs in the Canadian province of Ontario. It is classified as an endangered species in the US states of Indiana and New Hampshire. In Virginia, it grows in floodplain forests, mesic upland forests, and dry rocky woodlands. This species relies on appropriate habitat to persist; it can be removed from an area by development, changes in land use, or competition with invasive species.
