It cost about 7-10 years for Pistacia vera to give significant production. The harvesting then could elongate to 20 years.

As a drupe, the pistachio fruit includes three layers: the cover layer, the flesh and a shell protect an edible seed inside. This shell is hard with beige color and oval shaped and usually split apart when ripen. The kernel is in yellow-green color and has distinct fatty flavor.
