Rank Reasons
Endemic to the Southern Appalachians, Hypericum graveolens is known from North Carolina, where it is rare, Tennessee, and possibly Virginia. There are several occurrences in the Great Smoky Mountains National Park. The plant grows in roadside ditches, pathways, abandoned hillside orchards and balds that range in elevation form approximately 1200 to 2040 m.
Range Extent Comments
A Southern Appalachian endemic, ranges from northwestern North Carolina and northeastern Tennessee south to southwestern North Carolina (Weakley, 1996). Also occurs in Virginia according to Culwell (1981), although Kartesz and Meacham (1999) do not include Virginia in the distribution.
Occurrences Comments
Rare in North Carolina (Weakley, 1996). Probably five or six occurrences in Great Smoky Mountains National Park and many occurrences on Roan Mountain (Tennessee Element Ranking Form, Edwin Bridges, 1984).
Threat Impact Comments
Hypericum graveolens has a limited distribution, making it especially threatened by habitat loss and fragmentation (Southern Appalachian Species Viability Project 2002).
Ecology & Habitat

Habitat

Grassy balds, grassy openings, forest, at high elevations (1200 m or more) (Weakley, 1996). Grows in roadside ditches, pathways, abandoned hillside orchards and balds that range in elevation from approximately 1200 to 2040 m (Culwell 1981).
