Penstemon palmeri Penstemon palmeri
(Palmer's penstemon)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

A native of the Southwest, Palmer's penstemon sports sharp, prickly, gray leaves and thrives in the harsh conditions. Snapdragon-like pale pink flowers boom in late spring or early summer, and their sweet-honey scent attracts bumblebees. Toothed, sage green leaves skirt the upright stems for the rest of the gardening season.This perennial wildflower is one of the largest penstemons. It looks good in the back of a border or as a focal point, perhaps near a path where its fragrance can be enjoyed or in an informal grouping with other native penstemons and grasses, or with other plantss that have similar maintenance and water requirements. -Katie Nicolich, Plants to know and grow, Fine Gardening issue #120
