Large-Flowered Penstemon

Penstemon grandiflorus

Large-Flowered Penstemon features impressive, and large!, lavender-pink flowers that bloom profusely in late spring to early summer. Its moderate height and upright habit provide structure and visual interest to borders and native plant gardens. The tubular shape of the flowers is perfectly adapted to attract hummingbirds and other pollinators, adding a dynamic element to its garden performance. This Penstemon prefers full sun and well-drained soil, making it an excellent choice for xeric landscapes or rock gardens.
