This species is a herbaceous perennial with a few stems rising nearly straight up from a thick crown.

The leaves are entire and smooth, or possibly downy near the petiole.

The corolla is 24 to 32 mm (1 to 1.5 inches) long, deep blue with a violet tube, and smooth.

[1] This flower is native to the region from southern Wyoming and western Colorado south to northeastern Arizona and northern New Mexico[1] with an isolated population in Mono County, California[3] It is found in piñon-juniper woods, with scrub oak, or in open areas in ponderosa pine and spruce-aspen forest, often associated with sagebrush.

[1] Because of its combination of showy flowers, tolerance for drought, and hardiness, Rocky Mountain penstemon is often grown as an ornamental plant in dry regions.
