Penstemon calycosus is native to Botetourt and Lee counties, but is more widely distributed from Minnesota to Maine and south to Georgia. Best in full sun and average soil but tolerates filtered sun and dry soil. Snapdragon-like flowers about 1" long are produced in terminal panicles from June to July with some rebloom. Foliage is semi-evergreen in this area.
Direct sow in late fall sowing just below soil surface.  If planted in spring or started indoors, requires cold stratification.
