    Pollination Requirements: For cross-pollination, plant two Asian Pear varieties or one Asian Pear and an early blooming European variety like Ubileen or Rescue. Hardiness: Asian Pears are hardy to minus 25° F. Bearing Age: years after planting. Size at Maturity: ft. in height Bloom Time: Early April.
