Prunus serotina var. rufula (Woot. & Standl.) McVaugh
Southwestern black cherry, Chisos black cherry
Synonyms: Prunus serotina ssp. virens var. rufula
USDA Symbol: prser2
USDA Native Status: Native to U.S.
Following McVaughs description, Prunus serotina var. rufula is a variety of P. serotina that occurs from southeastern Arizona and New Mexico south through the Sierra Madre Occidental to the Mexican states of Durango and Guanajuato. It and variety virens are subsumed under subspecies virens, which is characterized by smaller size than more easterly varieties (to 30 ft. tall), generally diminished leaf and branch size, and an often shrubby form. Variety rufula is distinguished from variety virens by densely rufous-hirsutulous branchlets and raceme axes and shorter, stouter petioles 5-7 mm in length. Despite McVaughs description, widely referenced Texas botanist Benny Simpson has referred Texas populations to variety rufula, and other Texas plant writers have followed his example.

Seed Collection: : Collect
fruit when it is filled out, firm, and its ripe color. Clean seeds from pulp and briefly air dry. (Seeds to be sown immediately in fall do not need drying.) Storage viability is maintained at 31-41 degrees.
Maintenance: Keep fallen leaves, twigs, and branches picked up if you have herbivorous animals, as all parts except the
fruit are highly toxic.
