Origin - Native to China (Asia).

Other info. - P. calleryana is typically the first tree to bloom in the spring. The brilliant white flowers dominate the dull winter landscape of Missouri for a month or so. This species was introduced into cultivation in 1919. The "Bradford" cultivar came into cultivation in the 50's if memory serves me right. Other cultivars exsist which have different color fall foliage and different growing characteristics. Fruits can be absent to many small reddish pomes about 1cm in diameter.
