Pistachios, also known as the “smiling or happy nut” grow on Pistachio trees (Pistacia vera), a deciduous tree belonging to the Anacardiaceae or Cashew nut family. The female pistachio tree produces the nuts (in grape-like clusters) while the male pistachio produces the pollen. Pistachio tree farmers plant their male and female trees close together, even sometimes grafting them. Pistachios trees also rely on wind to assist pollination so the fruit can come to fruition.
