Outside of our building, there are two trees, both about 7-8 feet tall, with thin bark and kind of scalloped edged leaves. One one of these trees, there are some sort of fruit I guess…not really nuts, and not really berries. They’re about the size of an acorn (some a little larger) and resemble raspberries but firmer. The less “ripe” ones are green, but the more “ripe” ones are red, and the darker red they are, the squishier the fruit.
What kind of tree is it?
