Climbing Penstemon is a perennial shrub or vine native to southwestern California and northern Baja California. It typically grows 3-6 feet in length, but can reach 15 feet. The shrub blooms from May to July with showy red flowers and is very attractive to hummingbirds, bees, and butterflies. Climbing Penstemon thrives in part shade and well-drained soil, and makes an excellent ground cover or vine for shaded areas under trees.
