[SHIPS POTTED] When buying the Pistachio tree, you will receive the Peter's Pistachio tree (male) and the Kerman's Pistachio tree (female, grafted). This combo provides both trees as pollinators so that you get to eat pistachios! The Peters Pistachio tree is a seedling and mainly acts as the pollinator for the Kermans Pistachio tree which is a grafted cultivar of pistachio trees. The Kermans is a very prolific cultivar and is grown more than any other cultivar of pistachio trees due to its success. These trees require between partial and full sunlight as well as a well drained soil profile. (USDA Zones 7-10)
