Discussion

Menziesia pilosa is a southern and central Appalachian endemic occurring from southern Pennsylvania to northern Georgia. Although it can be locally common at high elevations in the southern Blue Ridge, it is of conservation concern in much of its range, including Georgia, Pennsylvania, Tennessee, and West Virginia.
