It is native to the eastern United States, where it is restricted to the states of Kentucky, Tennessee, Virginia, and West Virginia. Its natural habitat is acidic woodlands, prairies, and rock outcrops (typically sandstone or shale).[2]
This species was described to science in 1933 by botanist Francis W. Pennell, although it was subsequently included under Penstemon canescens or Penstemon pallidus in later 20th century treatments.[2] More recent botanists have elevated it back to the species level due to its morphological distinction and well-defined geographic range.
