Additional Information

Aristocrat is one of the better performing Callery Pear variants. Flowers are malodorous, but the later blooming Aristocrat flowers are not as often killed by late spring freezes as are the flowers of other P. calleryana variants. Some fireblight susceptibility, especially in the south. The branching of Aristocrat is more horizontal and does not form as narrow crotch angles as many other Callery Pears. Very small fruits are a litter problem when abundant. Considered invasive in many areas.
