Habitat: Wild Habitat
Environment description: Plants are growing from shade to part shade on a dry-mesic, well-drained upland/montane habitat characterized by an upland mixed deciduous and evergreen forest that is very rocky. Plants found in this habitat go through periods of drought during the growing season due to the limited litter/soil layer in which moisture can be held.
The underlying geology of this area is of Silurian origin and comprised of Shawangunk Formation. This formation is primarily light- to dark-gray, fine- to very coarse-grained sandstone and conglomerate containing thin shale interbeds.
