Found in a neighboring plot in our community garden
It is ~2 inches, maybe a little less. Slightly wrinkled, with a smooth, slightly waxy skin. Seems similar to a habanero, but the shape doesn't seem quite right. The skin gives off a very pleasant floral aroma, but it also smells like it could be quite hot.
It looked like it had very recently fallen off the plant, but we were unable to identify which plant it came from.
