Pistache Plant Information

Pistache grows in the following 6 states:

Georgia, North Carolina, Utah, Alabama, California, Texas

Pistacia is a genus of flowering plants in the cashew family, Anacardiaceae. It contains 10 to 20 species that are native to Africa and Eurasia from the Canary Islands, all of Africa, and southern Europe, warm and semidesert areas across Asia, and North America from Mexico to warm and semidesert United States, such as Texas or California.

Pistacia plants are shrubs and small trees growing to 5-15 m tall. The leaves are alternate, pinnately compound, and can be either evergreen or deciduous depending on species. All species are dioecious, but monoecious individuals of Pistacia atlantica have been noted. The genus is estimated to be about 80 million years old.
It is a genus of flowering plants belonging to the family Anacardiaceae. The plants are dioecious, have male and female trees independently; a viable population should have both genders.
Well-known species in the genus Pistacia include P. vera, the pistachio, grown for its edible seeds; P. terebinthus, from which terebinth resin, a turpentine, is produced; P. lentiscus, source of the plant resin mastic; and P. chinensis, the Chinese pistache, cultivated as an ornamental tree. The Pistacia species are vicarious Anacardiaceae with few species outside the Old World, and are mostly more adapted to water shortage and alkaline soil.
Many plant species are adapted to desert or summer drought typical of Mediterranean climate, so have a high tolerance to saline soil. They grow well in water containing up to 3.0 to 4.0% of soluble salts. They are quite resilient in their ecological requirements, and can survive in temperatures ranging from -10C in winter to 45C in summer. They prefer places oriented toward the sun and well-drained soil, but grow well in the bottom of ravines. Though very hardy and drought resistance, Pistacia species grow slowly and only begin to bear fruit after about seven to 10 years from planting, obtaining full development only after 15 to 20 years. The fruit ripens in the Mediterranean from August; only female trees have fruit.
Although some species prefer moderate humidity, they do not grow well in high humidity conditions. They are susceptible to root rot, molds, and fungi, and parasites attack if they receive too much water and the soil has insufficient drainage. They require a period of drought each year for proper development. Their leaves are intensely bright green and leathery, with three to 9 leaflets. The leaves are alternate, compound, and paripinnate. The flowers are unisexual, apetalous, and grouped in clusters. The flowers range from purple to green. The fruit is a drupe, generally unpalatable to humans, the size of a pea, and red to brown in color, depending on the degree of maturation. The seeds do not have endosperm. The seeds are eaten and dispersed by birds, for which they are a valuable resource because of the scarcity of food in some important times of year, as the time of breeding, migration, or the dry season. The commercial species of pistachio has larger fruits and is edible.
The plants emit a bitter, resinous or medicative smell, which in some species is very intense and aromatic. Some species develop "galls" that occur in the leaves and leaflets after the bite of insects. Although marred by the presence of galls, they are very vigorous and resistant plants that survive in degraded areas where other species have been eliminated. They multiply by seeds, stolons, and root shoots. Various species hybridize easily between them, and hybrid plants are difficult to identify.
Some tree species (e.g. Pistacia aethiopica, Pistacia atlantica) can exist as small bushes and shrubs due to the extremes of their habitat, adverse conditions, or the excessive consumption by wildlife or livestock that hinders growth.
Pistacia lentiscus is a very common plant related to Pistacia terebinthus with which it hybridizes. P. terebinthus is more abundant in the mountains and inland in the Iberian Peninsula, and mastic is usually found more frequently in areas where the Mediterranean influence of the sea prevents or moderates frost. There are species with very small ranges that cover only one or a group of islands in the Mediterranean. On the east coast of the Mediterranean, Syria, Lebanon, and Israel, Pistacia palaestina fills the same ecological niche of these species. On the west coast of the Mediterranean, the Canary Islands, and the Middle East, it can be confused with Pistacia atlantica.
Best known as the pistachio, Pistacia vera is a small tree native to Iran, grown for its edible seeds. The seeds of the other species were also eaten in prehistory, but are too small to have commercial value today. Records of Pistacia from preclassical archaeological sites, and mentions in preclassical texts, always refer to one of these other species (often P. terebinthus).
Pistacia terebinthus, a native of Iran and the western Mediterranean countries, is tapped for turpentine. P. palaestina, a similar species, is common in the eastern Mediterranean countries. These trees are both known as terebinth. Because it has the ability to kill certain bacteria, terebinth resin was widely used as a preservative in ancient wine. In the Zagros Mountains of Iran, in one of the earliest examples of winemaking, archaeologists discovered terebinth resin deposits from 5400-5000 BC in jars that also contained grape-juice residue.
Pistacia lentiscus, an evergreen shrub or small tree of the Mediterranean region, supplies a resin called mastic.
Pistacia chinensis (Chinese pistache), the most frost-tolerant species in the genus, is grown as an ornamental tree, valued for its bright red autumn leaf colour.
Pistacia species are used as food plants by the larvae (caterpillars) of some species of Lepidoptera including the emperor moth.
Bursera simaruba (L.) Sarg. was formerly classified as P. simaruba L.
