I ve been looking at gardining websites lately and I knew I saw a pistachio recently. Here it is: http://www.onegreenworld.com//product_in��Keep in mind the Sunset zones listed. If you don t have a guide to Sunset zones, and if you are serious about growing pistachio, you should look into it, because according to that website it won t grow well in much of the Bay Area. Zone 17 covers pretty much anywhere along the bay/coast, including San Francisco, Half Moon Bay, Oakland, San Mateo, parts of San Jose, San Rafael, Vallejo...etc. Zone 16 is some of the higher elevations around the bay.Also, wanting a nut tree to be 2-3 feet tall is like asking for a 3 foot elephant - it s not going to happen.
You could try the part of California where they are grown? Cant you look online for growers in the Central and Sacramento valleys?
