How to Identify

A tree. It grows 15 m high and spreads 6 m wide. The leaves are oval or rounded. They are yellowish-green. They have bristly teeth. The leaves turn red or bronze in autumn. The flowers are white. The fruit are greenish-brown.

How to Grow

Prefers a good well-drained loam in full sun. Grows well in heavy clay soils. Tolerates light shade but does not fruit so well in such a position. Tolerates atmospheric pollution, excessive moisture and a range of soil types if they are moderately fertile. Established plants are drought tolerant. A very frost resistant tree, tolerating temperatures down to below -15°, it is a possible rootstock for northern areas. It is used as a rootstock for P. pyrifolia culta in Korea. This species is a parent of the cultivated Asian pears.

Propagation: Seed is best sown in a cold frame as soon as it is ripe in autumn, when it will typically germinate in mid to late winter. Stored seed requires 8–10 weeks of cold stratification at 1°c and should be sown as early in the year as possible. Temperatures above 15–20°c can induce secondary dormancy. Prick out seedlings into individual pots when large enough to handle and grow on in light shade in a cold frame or greenhouse for their first year. Plant out in late spring or early summer the following year.

Medicinal Uses

Other Uses

The tree is used as a rootstock for Pyrus pyrifolia culta in Korea and is notably frost resistant.

Pyrus ussuriensis, also known as the Ussurian pear, Harbin pear, and Manchurian pear, is a species of flowering plant in the family Rosaceae. It is native to Korea, Japan, China, and the Ussuri River area of far eastern Russia. It has flowers in spring that are slightly pink when budding and then turn white. Buds are dark brown and have an alternating arrangement. The tree grows to a height of about 15 meters (49 ft) and prefers well-drained loam-type soils. It is considered the hardiest of all pears. When planted in milder climates, the trees have been known to be killed by freezes after they begin budding. Many species of birds and mammals feed upon the fruit of this species. Deer, mice, and rabbits are known to damage the trees. Leaves are dark green in spring and summer and turn dark red and gold in autumn. Products made from the fruits may prove more effective than commercial insecticides in killing ticks and mites. The fruits are not the tastiest of pears to humans, but the taste is better after a freeze and the juice tastes better. Crosses of this species with other pears produces tasty pears that grow in climates too cold for most pears. Cultivars include the 'Reli', 'Jinxiang', 'Hongbalixiang', 'Baibalixiang', 'Fuwuxiang', 'Qiuxiang', 'Fuanjianba', 'Longxiang', 'Guanhongxiao', 'Shanli24', 'Wuxiangli', 'Shatangli', 'Manyuanxiang', 'McDermand', and the Prairie Gem® Flowering Pear (cultivar ‘MorDak’). There are at least 108 compounds in the fruits that affect plant breeding and these show that P. ussuriensis cultivars fall into 4 groups.
