Located between the towns of Grana and Casorzo in Piemonte, Italy, is a very unique tree – well, they’re actually two trees, one growing on top of the other. Locally known as ‘Bialbero de Casorzo’ or the ‘double tree of Casorzo’, this natural oddity consists of a cherry tree growing on top of a mulberry tree.
No one really knows how the cherry tree managed to take root and survive in such a bizarre position. Locals believe that a bird might have dropped a cherry seed on top of the mulberry tree, which then grew its roots through the hollow trunk to reach the soil below.
