Pyrus calleryana ‘Aristocrat’ Aristocrat Callery Pear Small to medium deciduous tree with a narrow domed form and branching more horizontal than the species. Broadly ovate leaves, glossy dark green with distinct wavy margin. Autumn colours ranging from yellow to red. Prolific flowers in spring, however fragrance can be unpleasant. Bark is thin and easily damaged by mechanical impact. Must be pruned early to achieve good structure. Tolerant of a variety of soil conditions and will perform well where summer moisture is available. Shallow rooted tree. height x width (m) 12-15 x 8-10 origin Variety growth rate Fast flower colour White flowering time Spring shade tolerance Full sun drought Moderate tolerance, requiring summer moisture. low soil oxygen Moderate tolerance, prefers well drained soils. compacted soils Variable; widely planted in urban areas and generally grows satisfactorily. pest + disease Generally not prone to insects that cause obvious damage to foliage, susceptible to Fire Blight. root disturbance Moderate tolerance, evidence of successful recovery from root damage in urban landscapes. advanced Low incidence of problem from planting out as industry standard, 2m plus container grown trees. limb shear Few, if any reports of the shedding of major limbs in urban landscape plantings. ‘Aristocrat’ has wider branch angles and slower growth rate than ‘Bradford’ and therefore, the branches are better attached to the trunk. weed risk No records of species becoming established in urban landscapes by self-sown seed. under powerlines Not suitable. Moderately dense or erect canopy form that is poorly suited to training into an open centre under wires. habitat value Not known to provide a specific food or habitat resource for native fauna.
