Syn. Andenken an Friedrich Hahn'. 'Garnet' is a bushy semi-evergreen perennial to 90cm in height, wit racemes of tubular bell-shaped, deep wine-red flowers 3cm in length.

As with all penstemon do not give a autumn cutback but cutback when growth starts in the spring otherwise the winter weather will kill off your plant.
