- A very tight narrow pyramidal form, with multiple leaders. It has a moderate growth rate, reaching 35 x 15 ft ( 11 x 4.5 m) in 15 years. It grows up more than out so it is suitable for narrow spaces. However, Jacobson (1996) thinks there is more than one clone by this name since some trees are practically columnar. It flowers later in the spring than ‘Bradford’. Fall color is usually red-purple.
Full sun, regular watering, reportedly has good fireblight resistance
Hardy to USDA Zone 5 It was selected in 1959, the original tree was growing on public property in Cleveland, Ohio. Presumably the source of its cultivar name, 'Cleveland Select'. It was introduced in 1965 by the Scanlon nursery (PP 2489).
- Considered invasive. Callery pear (Pyrus calleryana) is reported as established outside cultivation in 25 states in the United States, sometimes forming dense thickets. The small fruit are eaten by birds that then disperse the viable seeds beyond the original area. The resulting plants are wild-growing descendants of multiple genotypes, originating in part from introduced cultivars. At lease two states have banned the sale of Callery pear, and the rulings go into effect in 2-3 years. Note: "The species cannot self-pollinate because of a self-incompatibility system, but recent fruit set is due to crossing between different cultivars or between the scion and rootstock of cultivated individuals. Consequently, individual cultivars themselves are not invasive, but the combination of cultivars within an area creates a situation in which invasive plants can be produced.
