Large Penstemon (Penstemon grandiflorus) is a striking native perennial of the Great Plains known for its large, tubular lavender-pink flowers and distinctive bluish-green foliage. Native to Nebraska and surrounding prairie states, this species typically blooms from late spring into early summer, producing upright flower stalks that attract bumble bees, hummingbirds, butterflies, and other pollinators. The smooth, waxy leaves form an attractive basal rosette that provides ornamental interest even when the plant is not in bloom. Large Penstemon thrives in full sun and well-drained soils and is highly tolerant of drought once established due to its deep root system. Because of its exceptional floral display and adaptability to dry conditions, it is a valuable addition to pollinator gardens, prairie restorations, native landscapes, and xeriscapes.
