Osage oranges, horse apples, monkeyballs, all synonyms for my favorite decorative fruit, which we refer to simply as "brains". The trees they fall from each autumn are pretty rare around here, but a few years ago I found a fruitful one which drops these goofy things on the public road. Going to scoop them up has become as much of a tradition as a trip to the pumpkin patch. They have a great citrus aroma and are credited with being a natural pest repellent and will stay rot free if kept cool for 2-3 months..
You just can't beat their lime green hue against the vivid orange of a ripe pumpkin.
I think God had some fun thinking this one up!
