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.
