General: Engelmann's Hedgehog Cactus (Echinocereus engelmannii) usually is a mound-shaped plant to about 1-1/2-feet tall and composed of several, stout, upright stems. Stems rarely solitary. The spines are long, flat, more or less straight, and dark colored with light edges. The flowers are purplish, and the fruits are spiny.

Engelmann's Hedgehog Cactus is a fairly common component of vegetation communities on gravelly and rocky soils along washes, rocky ridges, and upper bajadas and moderate slopes into the lower mountains in the Lower Sonoran (Creosote-Bursage Flats) and Upper Sonoran (Mojave Desert Scrub and Pinyon-Juniper Woodland) life zones.

Around Las Vegas, Strawberry Hedgehog Cactus can be found easily at Red Rock Canyon NCA (Calico Basin, Fossil Ridge), including in plantings around the Visitor Center.
