Dave,
It looks like something from the Nightshade family, probably something in the nightshade genus (Solanum). Most likely, the fruits contain the glycoalkaloid poison solanine, the same substance found in green potato peels (Solanum tuberosum). The fruits are probably bitter tasting and technically poisonous, but like green potato peels, not harmful in small amounts. I would taste the fruit to see if it is bitter or not. If its not bitter then it is likely edible, but would be good to identify it and research it before using it in quantity. If it is bitter tasting, then it is not likely food, but it would still
be nice to idenifty the species, just to know.
Good luck!
Sincerely,
Thomas J. Elpel
