This short-lived Midwest native boasts the largest flowers of any penstemon species. The rosette of glossy green leaves produces a flowering spike that can reach 30" tall. In early summer, the spike is laden with huge, lavender, bell-shaped flowers (occasionally pink or white occurs). In flower, this is truly a stunning native plant. P. cobaea must have very well-drained soils and a baking position in the garden to survive.
