Scientific Name: Pyrus calleryana ‘Chanticleer’ – Ornamental Pear
The autumn blaze, aristocrat, and chanticleer are cultivars of the callery pear. The autumn blaze is the most cold-hardy of cultivars. It produces fruit that in inedible to humans, but a favorite among birds. Unfortunately, this cultivar is also the most susceptible to the bacterial infection known as fire blight. The aristocrat cultivar is the thornless cultivar of callery pear. It is also less susceptible to wind and ice damage that other cultivars. The chanticleer cultivar is the most fire blight resistant of all of the cultivars. It is also the longest and most profuse flowering of all the cultivars.
