Alexander's Rock Aster Eurybia avita

Eurybia avita, commonly called Alexander's rock aster, is a rare North American plant species, a herbaceous perennial in the family Asteraceae that was formerly considered part of the genus Aster. It is native to the southeastern United States. It is of conservation concern as it is found in less than 50 sites, typically only in sandy soils near granite flatrocks, and it is most likely already extirpated in North Carolina. Its habitat is threatened by development and the recreational use of the area where it grows. It is very similar to both E. surculosa and E. paludosa and more research needs to be done to determine the exact relationship between the three species. Wikipedia →
