Mountain bellwort (Uvularia pudica) is a small perennial herb that grows clonally, raising multiple individual stems (or ramets) from horizontally growing rhizomes. Ramets grow from 10-30cm tall and branch once, just above their midpoints.
Vulnerable in the nation or state due to a restricted range, relatively few populations (often 80 or fewer), recent and widespread declines, or other factors making it vulnerable to extirpation.
Mountain bellwort grows in mountain woods.
Though it is ranked as secure in Maryland, West Virginia, and North Carolina, mountain bellwort is much rarer at the north end of its range. It is classified as endangered in New Jersey and New York, and as rare in Pennsylvania, where five closely clustered populations are recorded.
Existing mountain bellwort populations will benefit most from the protection of their habitat; protected areas should be large enough to allow population growth. Control of deer browsing will likely be important, as will management of exotic plants.
