In the summer months (May - August) you can find blooms ranging from blue to purple on clustered stems that arise from a woody root crown. This penstemon sends up stems that are 8 - 16 in tall and die back after blooms are spent. 

This penstemon’s large, oval leaves are evergreen, but if deprived of sufficient water they may turn a deep purple.
