Himalayan blackberry is the most common introduced blackberry in British Columbia.
This species is an aggressive invader that was introduced for its excellent fruit and has become naturalized in many parts of the world. In the Pacific Northwest it occurs from California to British Columbia. Several scientific names have been used for this plant. Eurasian blackberries are an extremely variable complex of small apomictic species. Prof. H.E. Weber in Germany helped me to answer the question of the correct name for our Himalayan Blackberries.
