Scientific name: Pistachia chinensis
The Chinese Pistachio is a medium sized ornamental tree from China and Taiwan that is extremely winter hardy
and has a superior level of drought, heat and wind tolerance. The Chinese Pistachio is the first shade tree to
receive the coveted "Earth-Kind" designation from the Texas Agricultural Extension Service for its high levels
of genetic resistance to insect and disease problems. The Chinese Pistachio has extremely hard, durable wood
which helps protect the tree from wind, ice and decay. Chinese Pistachio trees have a medium to fine textured
foliage that remains an attractive deep green color during the growing season and a spectacular fall color in
shades of orange, red, and crimson. In the summer the female Chinese Pistachio produces panicles of inconspicuous
red dish flowers that are followed by small green berries that turn red to reddish-purple in the fall, which
are relished by birds.
Description: Related to the deciduous sumacs (Rhus species). Not only are the leaves similar to sumac,
Chinese Pistache has the same luminous orange-red autumn color. Although young trees may not grow symmetrically,
in time they become regular and rounded to 60 feet tall and nearly as wide. With a male tree nearby, female
trees will bear small red fruits; these turn dark blue when they ripen but are not especially showy. This is
the only tree adapted to desert conditions that will provide bright red autumn color. Reliable tree for parks,
street, lawn, patio, or garden corner.
Leaves: Foliage comprised of 1-foot long leaves with 4-inch, narrow, paired leaflets.
Fruit: Fruit on female trees bright red, turning dark blue.
Bark: Shallow ridge and furrows when older. Orange lenticels on the twigs.
Height: 40-60 feet
Hardiness Zones: 7 to 10 (southern New Mexico to Florida). Winter temperature tolerance of 10 down to zero degrees.
Soils: Tolerates a wide range of soils, including moderately alkaline.
Water Needs: Regular watering until well established - at least two years. Then it is drought tolerant,
needing only occasional deep watering.
Disease: Resistant to oak root fungus. Is susceptible to the root fungus that kills Russian Olive, as
are members of the sumac family.
Care: Stake young trees and prune them for the first few years to develop head high enough to walk under.
