We found this "fruit" growing on our vine. This vine covers our entire chimney and we have never noticed if it has flowered. After letting it get quite overgrown this past summer, we started trimming it today. Then we discovered these green fruit looking things growing all over it. We have found these in our driveway before but thought they came from someone's kid throwing them around outside. When cut off the vine, it releases a sticky, white liquid. 3 Any clue what it might be?
