Common names: Himalayan or Armenian blackberry
Rubus armeniacus is an extremely invasive plant in our region and pops up even in heavily cultivated areas of our Garden. It was introduced by Luther Burbank in the early 20th century but soon grew out of control along the Pacific Coast. It overwhelms our native blackberry, R. ursinus. It blooms in late spring and berries follow in late summer.
