Shrubby penstemon
Penstemon venustus
Shrubby penstemon is a semi-woody native perennial producing showy lavender-purple tubular flowers that attract hummingbirds and bees throughout late spring and summer. It prefers well-drained to rocky soils and tolerates dry conditions well once established, making it ideal for low-water western gardens. Trim lightly after flowering to maintain a tidy habit and encourage repeat blooming.
