Himalayan Blackberry

Himalayan blackberry is a very invasive, very pokey, and very stubborn weed. In the summer it will have white flowers that turn into green, then red, then black, berries. The stalk of this plant can get huge, and the dead and dry stalks are as sharp as a sword. You should be very careful around this plant. If you can, pull it out. You might need pruners, gloves, or other additional tools. Blackberry is stubborn.
