A cherry tree growing out of the bowl of a mulberry tree.
If the Bialbero di Casorzo was planted by human hands, it was not claimed. Its plaque speculates that a bird may have dropped a cherry pit from a nearby orchard into the crown of the mulberry some 200 years ago. It stands outside of a small town in Italy, near Turin.
The cherry is not grafted into the mulberry, but rather has grown on and through it, eventually reaching the ground with roots that extend through the trunk of the mulberry. They flower, leaf out, and fruit at different times; the cherry in particular is known for its lovely white flowers in the spring.
