Endangered by habitat loss, damage by off-road vehicles and woody succession of barrens habitat. Pettingill and Neel (2008) confirmed that Maryland plants were sister to the sample from Missouri (within the core range of the species) but indicate that further investigation may be warranted to determine if the Maryland populations are actually an unrecognized species, as our populations are striking disjuncts from Midwestern prairies (MD DNR).
Sandy roads, barrens and fields (MD DNR).
