Large, grape-purple flowers that hummers love, bloom in late spring to early summer — a superb hybrid developed in Colorado for hardiness. These plants are vigorous, with glossy green foliage and a lax habit. They are drought-tolerant, but, unlike many Penstemon, are happiest with fertile soil and some water. 2' x 2'Minimum temperature: -20° F
