General: Stansbury Cliffrose (Purshia stansburiana) is an stout, upright shrub or subtree growing to head-high or higher. The plant produces many white, wildrose-type flowers in the spring, and each flower produces five seeds, each with a feathery plume attached.

Cliffrose is a common component of vegetation communities on upper bajadas, ridges, and dry slopes in the Upper Sonoran (Mojave Desert Scrub and Pinyon-Juniper Woodland) and Transition (Yellow Pine Forest) life zones, from just below the Pinyon-Juniper Woodland upward to the lower Yellow Pine Forest.

Around Las Vegas, look for Cliffrose at higher elevations in places such as the top of the Red Rocks Scenic Loop, the Sheep Range in the Desert National Wildlife Range, and up on Mt. Charleston.

Family: Rose (Rosaceae).

Other Names: Cliffrose; Cowania mexicana, Purshia mexicana var. stansburiana

Plant Form: Stout, upright shrub or subtree with thick stems and shaggy bark.

Height: 5-9 ft.

Bark: Brown, shaggy.

Stems: thick near the base, many branching, upright.

Leaves: Small, pinnately compound (5–9 lobes), edges rolled under, alternate, deciduous, dotted with glands. Leaves clustered on short lateral branches.

Flowers: Blooms late spring to early summer. Flowers typical wildrose type, solitary on branch tips, but produces enough flowers to cover parts of the shrub. Petals 5, creamy white, to about 1/3 inch long. Many stamens with yellow pollen; sometime making the entire flower appear yellow.

Seeds: oblong with a long, feathery plume; five plumes per flower.

Habitat: Dry, well-drained sandy, gravelly, and rocky soils on upper bajadas, moderate slopes in the lower mountains, and rocky ridges.

Elevation: 3,500–8,000 ft

Distribution: California to Colorado and south into northern Mexico.

Comments: Cliffrose has undergone a number of name changes in recent years, making the taxonomy somewhat confusing.

Cliffrose (Purshia stansburiana) and Bitterbrush (Purshia tridentata) occur in the same habitats, flower at the same time, have similar flowers and leaves, and hybridize.

Flower is a typical wildrose type with five petals and many yellow stamens.
