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.

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.
