  • The Obsidian blackberry is a combination of the marionberry, olallieberry, and the boysenberry, developed at OSU in Corvallis, OR. When these dark berries jalm up, they develop a flavor like red zinfandel. The balance of sweet and tart in the obsidian blackberry has earned them the nickname of “Jammer’s Delight”.
