Pistachio Tree (Pistacia vera) Information

Pistachio is a deciduous small tree with branching growth and a low decorated crown of five oval lobes with gray-green pinnate compound leaves. It is dioecious, with separate male and female trees. Flowering in spring, male and female flowers are brown-green with no petals. After the female flowers, the reddish soft shells overlap and contain hard-shelled pistachio nuts. At maturity, the shell splits along the long axis. When the shells come off easily, it is time to harvest.

Pistachios are wind-pollinated and both male and female trees must be planted for successful pollination and fruiting. It is long-lived (several hundred years), with maximum fruiting after about 20 years. Pistachios grow best in areas with hot summers (they do not like humidity) and cold winters. For best production, it is important to meet the required cooling time.

  • The fruit is a kernel with elongated seeds, which are edible. The seeds are generally considered nuts, but they are edible nuts, not vegetable nuts. The outer skin of the fruit is creamy and hard. The seeds have a light purple skin and light green flesh with a distinctive flavor. When the fruit ripens, the husk changes from green to an autumnal yellow or red color, and parts of it suddenly break off. This is called “shedding,” and a “popping” sound is heard. This splitting is a trait selected by human hands. Commercial varieties vary in the stability of the splitting process.
  • Pistachio trees harvest an average of about 50 kilograms (110 pounds), or about 50,000 seeds, every two years.
