Rocky Mountain Penstemon, Rocky Mountain Beardtongue, Strict Beardtongue, Toadflax Beardtongue
A long-lived western native, Penstemon strictus (Rocky Mountain Beardtongue) is an evergreen perennial boasting abundant spires of large, royal-blue to purple flowers rising above a low foliage mat. Blooming for several weeks in late spring and early summer, the tubular flowers attract scores of hummingbirds, bumblebees, and other beneficial pollinators. The lustrous emerald green leaves, ranging from grass-like to lance-shaped, remain fresh-looking year-round. The beautiful flowers and handsome evergreen foliage make Penstemon strictus attractive for ornamental and landscape plantings. Easy to grow, fuss-free, water-wise, it is perfect for the sunny garden.
