10 Seeds Showy Penstemon Wildflower Native Plant Penstemon spectabilis

Showy Penstemon is a striking native wildflower known for its tall spikes of vivid violet-purple blooms that attract hummingbirds and pollinators to the garden. This perennial species brings dramatic vertical color to sunny borders, meadow plantings, and drought-tolerant landscapes.

Its tubular flowers bloom in late spring through summer above sturdy upright stems and gray-green foliage. Excellent for naturalistic plantings, pollinator gardens, and cut flower arrangements, it performs best in well-drained soils with minimal supplemental water once established.
