Davidson's penstemon is a low-growing California native perennial that forms a dense mat of evergreen foliage, making it an excellent choice for rock gardens, slopes, and garden borders. Growing just 2–4 inches tall and spreading up to 24 inches wide, it produces showy blue-lavender to purple, tubular flowers in spring and early summer that attract hummingbirds and native bees. Thriving in well-drained soils and full sun to partial shade, this drought-tolerant penstemon adds vibrant color and year-round texture to native and alpine-style landscapes.
