If it is an actual edible/dessert type, and you're not sure right now, it may take til the time it fruits to figure it out. There are a few signs when young though, such as if it has red blotches on the leaves, or if it has a slight blue haze to it with a red outline, and as it matures, there's other signs such as how tall does it get. Either way, for a dessert type, the best protection for it is either digging it out and moving it to a frost-free cool dry area over winter or mulching it and protecting the p-stem with things like blankets, insulation wrapping, leaves, etc. Some people just chop that down and protect the ground though, however that method will not allow fruiting to happen anytime soon.
