Penstemon serrulatus (Coast penstemon) is a low-maintenance, wildlife-supporting native perennial treasured for its elegant form and dependable blooms. Native to the Pacific Northwest, it naturally grows in open woodlands, forest edges, meadows, and coastal lowlands. Blooming from late spring into early summer, its tubular flowers offer a vital nectar source for pollinators emerging after winter.

Coast penstemon thrives in full sun to partial shade and prefers well-drained soils, including loamy or slightly rocky ground. Once established, it is moderately drought-tolerant, long-lived, and clump-forming, making it easy to integrate into both naturalistic and designed landscapes. It does not spread aggressively and coexists well with other native plants.

Graceful, resilient, and quietly showy, coast penstemon brings structure, early-season color, and ecological value to gardens and restoration projects alike.
