It is native to eastern California and western Nevada, where it grows in forests and scrub in desert and mountains.[3][4] It was named after Charles Lewis Anderson by Asa Gray.[5]

Prunus andersonii is a shrub approaching 2 meters (80 inches) in height, its tangling branches narrowing to spiny-tipped twigs. Serrated, lance-shaped to oval leaves occur in clusters, each leaf measuring up to 3 centimeters (1+1⁄4 in) long. The shrub is deciduous. The inflorescence is a solitary flower or pair of flowers. Each flower has usually five concave pink petals each just under 1 cm (3⁄8 in) long, with many whiskerlike stamens at the center. Flowers bloom before or at the same time as the leaves appear.[6] The fruit is a fuzzy reddish-orange drupe around 1 cm (3⁄8 in) wide. The fruits are fleshy in years with ample moisture, and dry in drought years.[6] The seed is a heart-shaped stone.[6] The plant reproduces sexually via germination of the seed, and vegetatively by sprouting from its rhizome.[6] One plant may sprout and resprout from its rhizomes to form a very large clone which can spread over several acres.[6][7]

Many rodents collect and eat the fruits and cache the seeds.[6] Among Native American groups, the Paiute used this plant for making tea and medicinal remedies, and the Cahuilla considered the fruit a delicacy.[8]
