"The Callery Pear tree, Pyrus calleryana, 'callery X Aristocrat cultivar', is a tight, narrow, pyramidal, thornless, ornamental pear tree. Some specimens appear almost columnar in habit. Oval, glossy green leaves turn an attractive reddish purple in autumn. The growth habit is dense, narrowly pyramidal, and evenly branched with crisp glossy green foliage. Callery Pear trees are very hardy and fast growing. They are an excellent choice for a trouble-free, beautiful addition in any landscape situation."
