Discussion
Penstemon buckleyi frequently is found on aeolian sands of dune fields associated with the major streams of the southern Great Plains; it also occurs on alluvial sands and sandstone-derived soils. It has been documented in Banner and Platte counties, Nebraska, well north of its native range; those plants probably represent roadside introductions (R. B. Kaul et al. 2006).
