Type of Blackberry
I was digging up some blackberry bushes and found two varieties growing in the same spot. One is either a blackberry or black cap, but the other variety has green stalks and the same blackberry leaves. What are these, and should I avoid planting them with the blackberries?
its possible if you blackberries were graphtid and this plant is your original plant,its possible that that other plant growing there is the host plant that the nursery graphtid your original plant to.Its a possibility
