Well, may or may not be wild. There are also blackberry bushes nearby that have been there since I can remember (first year fruiting though!). All I really know is that the fruits are sour and they seem to have a single seed in the middle. I'm sure they're probably immature/unripe.
Edit: I haven't eaten one because I don't know if they're edible or not. Biting into one reminded me of a crab apple though.
Any clues are appreciated.
