Among the most exuberantly blooming plants this side of the Mississippi, Penstemon are part of the enchantment of the West. A member of the Snapdragon family, even cultivated varieties retain a natural air, with dainty, long trumpet flowers and 5 (pent) prominent stamens. Sturdy and easily cultivated, species usually range from 1 to 3 ft. tall, and vary in color from white to pink to purple to deep wine-red to blue—one for every sunny spot. Trim after the first bloom to encourage a repeat flowering, and cut to the crown in autumn for strong growth next season.
