Narrative

Description: Pyrus betulifolia was introduced at the Arnold Arboretum in 1882 from the mountains near Peking. The pears have no value as a source of food but the trees proved to be promising. Although Reimer of Oregon has reported that this species is susceptible to fire blight in Oregon, this has not been the case at the Arnold Arboretum nor anywhere else in the East. In addition, the seedlings have been reported to be free of leaf-blight. The young plants can grow vigorously from seeds or cuttings and can bud throughout the long season. They are also compatible with many other pears in China. And, because this species is widely distributed in China it is possible to obtain seeds that would give rise to trees that do not deviate from the parents.
