Shrubs Around Las Vegas, Vegetation Around Las Vegas
Desert Almond (Prunus fasciculata)
Leafless plant during winter; twigs widely diverging

General: Desert Almond (Prunus fasciculata) are robust, twiggy shrubs almost always found along washes. The species is deciduous, but even without leaves, this twiggy shrub with angular joints, spiny tips, and branches with leaf fascicules, is recognizable.

The leaves are narrow, about 1/3- to 1/2-inches long, and grouped in clusters on the tips very short lateral branchlets. The lateral branchlets, appearing like bumps on the side of a branch, are referred to as fascicules, and the leaves are said to be fasciculated [fascicule = a bundle of structures].

Desert Almond is a common component of wash communities in the Upper Sonoran (Mojave Desert Scrub and Pinyon-Juniper Woodland) life zones.

Family: Rose (Rosaceae).

Other Names: Desert Peach

Elevation: Generally 3,000 to 6,500.

Distribution: Utah to Baja California

Comments: This is one of the species most often seen along washes around Las Vegas.

Western Tent Caterpillar Moths (Malacosoma californicum fragile) usually lay their eggs in Desert Almonds. The eggs hatch, and the caterpillars build a "tent" for protection while they feed on leaves. When present, this is a good way to identify this plant species in our area.
