A medium sized tree. It grows 15 m high and spreads 9 m wide. The leaves are oblong and have teeth along the edge. The leaves turn orange and bronze in the autumn. The flowers are small and white. They appear almost the same time as the leaves. The fruit is round and the size of an apple. The skin is thin. They can be green, yellow or bronze. They have a gritty texture. Some forms have larger, softer fruit. These cultivated forms may be crosses between Pyrus pyrifolia and Pyrus ussuriensis. These are oval and yellow with a crisp texture.
Differing in its more sharply serrate lvs, slightly larger fls, and subglobose fr, seldom escapes in our range.
It is a temperate plant. In Vietnam it is cultivated in the northern highlands between 1,000 and 1,500 m altitude. It needs 300-800 hours of cold below 7°C each year. They are hardy to frost. They will grow on most soils. In Hobart Botanical gardens. In XTBG Yunnan. It suits hardiness zones 4-9. In Sichuan and Yunnan. Arboretum Tasmania.
