Great article and thank you. What I really want I really want to know is will they grow and fruit in Georgia or are we too hot? I have what was called a "Chinese Pistacio" that I planted when we moved here years ago because they were all over Sonoma, CA. but I have never seen a blossom cluster on it.
I don't think the Chinese Pistachio, known as Chinese Pistache (Pistacia chinensis), will produce the commercial pistachio nuts that you may be thinking of. Although, the Chinese Pistache can be used as the understock for grafts of commercial Pistacia vera trees. Chinese Pistacia trees are hardy to zones 6b through 9.
