Description
The Spruce Eats says: Not all blackberries are marionberries, but all marionberries are a type of blackberry. They differ, however, in shape, as marionberries are more oblong, and tend to be sweeter and juicier.
An extremely vigorous plant with canes up to 20′ long. Be aware that these canes are VERY spiny but of course great for keeping out intruders of any species.
