Bialbero di Casorzo (2005)

The Bialbero de Casorzo (Italian: "double tree of Casorzo"), which is also known as Grana Double Tree, is a unique tree situated between Grana and Casorzo in Piemonte, Italy. It is a mulberry tree on which a cherry tree grows. The cherry tree rises well above the mulberry tree on which it stands.[1]

Epiphytical growing trees are not unusual, but they normally reach a small size and have a short lifespan, as there is normally not enough humus and space available where they grow.

Large Epiphytes like this one require the "upper tree" have a root connection to the ground, for example by growing down through a hollow trunk. A similar "double tree", consisting of a peach and a spruce in the Plitvice Lakes National Park in Croatia, was described in an edition of the Cosmos booklets[clarification needed] of the 1960s.[citation needed]
