Armenian or Himalayan Blackberry (Rubus discolor/procerus & aremeniacus)

Invasive Himalayan or Armenian blackberry can be found throughout the Pacific Northwest and takes a little effort to get rid of!WMSWCD Urban Conservationist Mary Logalbo shows you the easiest way in this video.

Armenian blackberry is a perennial which blooms from June – August and its root balls produce upright reddish stems or canes with sharp spines that can grow

more than 20-feet per season. The leaves are serrated and the white-to-light pink flowers have five petals.

Armenian, or Himalayan, blackberry is the most widespread and disruptive of all the noxious weeds in Western Oregon. It displaces native species, dominates riparian habitats, and costs millions of dollars to control in parks, right-of-ways, forests and agricultural areas. It reproduces by canes and seeds, the later of which is carried by birds and animals.

The best way to control blackberry is to cut it down to the ground and dig out the roots.
