Rubus armeniacus, the Himalayan blackberry[2] or Armenian blackberry, is a species of Rubus in the blackberry group Rubus subgenus Rubus series Discolores (P.J. Müll.) Focke. It is native to Armenia and northern Iran, and widely invasive elsewhere. Both its scientific name and origin have been the subject of much confusion.

It is considered the most invasive nonnative shrub on the West Coast, where it forms large thickets, displaces native plants, hinders wildlife movement, and causes economic losses. It is most common in mediterranean climates and prefers moist, well-drained soils. It is most invasive in low-elevation riparian, hardwood, and conifer communities.

Rubus armeniacus (Himalayan blackberry), formerly known as Rubus discolor, is a sprawling, essentially evergreen, glandless, robust shrub (family Rosaceae). Rubus armeniacus occurs in California in the coast ranges, Central Valley, and Sierra Nevada.
