Botanical Interests® Penstemon Rocky Mountain Blue



A long-lived, heirloom penstemon, Rocky Mountain Blue enhances the garden all year. Its exquisite blue-violet flower spikes attract pollinators and bloom for about a month in early summer, followed by satiny brown teardrop seedpods. In winter, the plants’ evergreen basal rosettes turn from green to reddish purple. An easy to grow, very hardy and drought-tolerant choice for both wildflower plantings and formal garden borders.
