It is native to the eastern United States, where it has a highly fragmented range localized in the Northeast, the Upper Midwest, the Interior Highlands, and the Southeast. Its natural habitat is typically on rocky or sandy woodlands and bluffs, in areas of acidic soil. It is generally uncommon throughout most of its range, with exception for the Interior Highlands region.
