On the hills of Monferrato, halfway between Asti and Casale Monferrato, the small town of Casorzo is home to a curious natural wonder: a double tree or a cherry tree grown on a mulberry tree. How it is formed For the more curious (or just curious) green thumbs, this is the most accredited theory to explain the birth of the double tree, otherwise known as the double tree of happiness: probably a bird or other small animal has the cherry seed on the inside of the hollow trunk of the mulberry tree. Somehow the roots worked their way to the ground and the plant began to grow on top of the mulberry tree, finding enough nourishment to fully develop. Et voilà, the double mast is ready! When should you go and see the Casorzo double shaft? In the middle of summer, with both plants completely green, the strange phenomenon of the "double tree" tends to go a bit unnoticed. In the spring, however, he does his best. If you've always dreamed of living the Japanese experience of Hanami, the practice of admiring cherry blossoms, you can always start here: between March and April, the cherry tree turns white, while the mulberry tree underneath is still bare. This is the time of year when the gap between the two trees is most obvious and spectacular. The double tree and the furnished area in which it stands are located directly on the path Malvasia di Casorzo . The access to the area is always free and with its tables it lends itself perfectly to receiving anyone who wants to stop for a break during an excursion or even just to those who want to have a picnic in the shade of a very special tree.
