Habitat Description:

Rich forests and woodlands, rocky bluffs over mafic or calcareous rocks, and also cultivated and persistent. Generally rare and widely scattered over the western half of NC; not as easily found as is P. hirsutus, as that species can be more readily targeted in its more restricted rocky slope and bluff habitats on high pH soil. It usually does not occur in large stands, though a few ravines and slopes may contain dozens of individuals. As this species is often planted, it has some ability to escape into places where it is not clear if native. This is an N.C. Watch List species.
