Armenian Blackberry

The Armenian blackberry (Rubus armeniacus), also called Himalayan blackberry, is native to Armenia and Northern Iran, but grows abundantly in this area. It produces sweet edible fruits in the summer and prickly vines all year long. This aggressive plant is considered an invasive species in many parts of the world, including in the San Francisco Bay Area. Birds and other animals eat the fruit and then spread its seeds, making it very difficult to contain.
