Permaculture uses
The Chinese Pistache is primarily used as an ornamental shade tree in permaculture systems. It offers vibrant fall color. While the fruit is technically edible, it is generally considered unpalatable for direct consumption. However, it can provide food for birds and other wildlife. The tree's strong root system can help stabilize soil. No significant medicinal uses are commonly reported.
Permapeople description
A cultivar of Pistacia chinensis known for its vibrant red fall foliage.
Botanical description
Pistacia chinensis integerrima is a deciduous tree typically reaching 30-60 feet tall and wide, though size can vary. It exhibits a rounded crown and a single or multi-trunked form. The bark is gray-brown and becomes furrowed with age. Leaves are pinnately compound, with 10-14 lance-shaped leaflets that turn brilliant shades of red, orange, and yellow in the fall. The tree is dioecious, meaning male and female flowers are borne on separate plants. The flowers are small, inconspicuous, and greenish. Female trees produce small, round, reddish drupes that turn blue-black when ripe. These fruits are about 1/4 inch in diameter. The integerrima subspecies is characterized by its entire (uninterrupted) leaflet margins.
Companion planting
Chinese Pistache is generally considered a good companion plant for other trees and shrubs requiring similar growing conditions (full sun and well-drained soil). Avoid planting it near plants susceptible to Verticillium wilt, as Pistacia species can be carriers.
Propagation methods
Propagation is typically achieved through seed. Stratification of the seeds is necessary to break dormancy. Cuttings are also possible, although success rates may be lower. Grafting is sometimes used to ensure desired characteristics, particularly with female trees for fruit production.
History and traditions
Pistacia chinensis has a history of use in traditional Chinese medicine, though less commonly than other Pistacia species. It has been cultivated in China for centuries, primarily for ornamental purposes and its timber. In Western horticulture, it has gained popularity as a drought-tolerant and adaptable shade tree.
Usage calendar
Flowering occurs in spring (April-May). Fruit ripens in fall (September-October). Planting is best done in the dormant season (late fall or early spring). Pruning should be done in late winter or early spring before new growth begins.
