Bought this plant in a local supermarket but cannot remember what it is. The berry itself looks like a small raspberry but shiny like a blackberry. It tastes sweet.
Yes, this looks very much like a wineberry. It's a type of raspberry. Wineberries are one of my favorite raspberries and one of the only I've ever seen that produce reliably in the shade. It is considered semi invasive in some areas so just beware.
