I first saw this fruit on the New England seacoast a few weeks ago. Finding it intriguing, and completely clueless as to what it was, I took a photo, determined to look it up as soon as possible. Imagine my surprise, on arriving home, to find the exact same fruit (in photo above) on a tree growing in my garden! Had I looked at the entire tree, back there in New England, I could have figured out its identity. At any rate, now I know what it is. Do you?
