But I am not sure if this is what you are looking for?

If you are looking for a plant to grow pistachio nuts in this country-I don't think that is possible

It is grown in hot, hot countries with long summers and mild winters-it may tolerate a certain degree of frost- but we do not have the Summer conditions to grow it

As far as I am aware no commercial growers cultivate this here -which tells its own story,
