What Tennessee tree fruit is size grapefruit, green, aromatic, bumpy?

Monkey Balls are kiwi fruit.

In PA and NJ I heard them called “monkey brains”. I’m pretty sure we also called them Osage Oranges.

A common term for osage oranges here in Kentucky is spider ball, because of their reputation for keeping spiders (and other insects) away. We tried it in our basement, but the fruit just rotted. :frowning:

I’ve got a chunk of a tree in my basement right now just for that purpose. I cut it down about 12 years ago. I’ve left the bark on, and painted the ends to help reduce the splitting as it dries. Don’t know when I’ll get around to making a bow, but if I don’t, I’ll be happy to let someone skilled in the art have a crack at it.
