Class C noxious weed in Washington, found along roadsides and in forests. This Asian native out-competes native understory plants and blocks water access for wildlife. Goats will eat blackberries to the ground. The berries ripen in late summer and make excellent jam, jellies, and pies. A good way to harvest is to flop a 2x8 board directly into a patch, then walk the plank, picking along the way. It is a safe and gentle astringent and may be used for diarrhea. Blackberry tea may reduce high blood pressure or reduce the sugar levels in diabetics.
