Specification :

Pistachio nut is the fruit of a treelike plant ( scientific name of Pistacia Vera ) that grows in clusters. The kernel is yellowish green and covered by a peel firmly adhered thereto. The enlarged nut pushes on the surrounding hard beige shell to cause a natural split, while the hull, which serves as a protective cover for the shell, usually remains intact.
The pistachio trees blooms during April and the kernel develops during the month of July. Pistachio usually ripens in 2nd half of September
