Himalayan blackberry, also known as Rubus armeniacus, is a European species of blackberry that is invasive and dominant in the Pacific Northwest. You an find many blackberries throughout many Seattle, Washington parks and their berries are abundant during the summer time, particularly in August. Their seeds are viable in the soil for years and as they are reproduce well during dry summer, global warming would increase the reproduction of the blackberry ("Noxious Weeds." Himalayan Blackberry and Evergreen Blackberry Identification and Information").
To identify this species, it can generally grow up to 15 feet tall and 40 feet long. It has small, white/ pink-colored flowers that may be found on the plant. The leaves are toothed on the edges and are grouped in 5 on the main stems. Although the roots cannot be seen, if attempting to remove these species, their large and deep root balls make this task difficult as they are embedded deep into the ground ("Plants Profile for Rubus Armeniacus").
This species is highly invasive and difficult to control as it does so well under the Pacific Northwest conditions. Its legal status is currently class C of noxious weeds on the Washington State Noxious Weed List, according to King County. Himalayan Blackberry has been listed as an invasive species since 2009. Property owners are not allowed to control these species, meaning that they cannot maintain and grow them ("Noxious Weeds." Himalayan Blackberry and Evergreen Blackberry Identification and Information").
