Native in Arizona and New Mexico. This penstemon is a woody sub-shrub that grows about 2 feet tall and wide, and has short needle-like foliage that is evergreen. The flowers are red, narrow tubes, blooming in summer. There are a number of other forms available, including yellow and orange, and more compact or taller. It has a long bloom season and good foliage. Is attractive to hummingbirds; not so to rabbits.
As with most other penstemons, plant in full sun and well-drained soil. Gravelly, poor, sandy-loam, clay-loam; just make certain it drains well. A light shearing after it has bloomed will keep it looking tidy.
