Pyrus calleryana 'Aristocrat'

Aristocrat Callery (Ornamental) Pear

Form and Growth Characteristics:
Plant Type - Tree
Growth Rate - Fast growth rate. Oval to broadly pyramidal.
Mature Height - 40-45'; central leader may be lost with time
Mature Width - 20-25'
Longevity - Can live long periods of time if it in the correct environment. However, as the tree reaches maturity, the many weak branch attachments have a tendancy to break apart (though this is less of a problem with this cultivar).

Ornamental Characteristics:
Flower - White flowers, 0.375-0.75" across, borne in 3" diameter corymbs before or with the leaves. In full bloom for a week in March/April. The somewhat unpleasant odor becomes more noticable when several of the trees are clustered together.
Fruit - Small rounded pome, 0.5" or less across, russet-dotted, hidden by the foliage; not ornamentally effective. Usually present in great quantities; seedlings readilly invade unmaintained fields and road sides.
Leaf - Alternate, simple, broad-ovate to ovate, 1.5-3" long, about as wide, rarely elliptic-ovate, short acuminate, rounded, broad-cuneate, subcordate or truncate at base, crenate, usually quite glabrous, leathery, lustrous dark green; petiole-1-1.5" long.
Fall Color - Yellow-to-red, variable
Bark - Lustrous brown in youth, lightly ridged-and-furrowed and grayish brown at maturity, often developing horizontal checks with age, creating a somewhat blocky appearance.
Other Features - Over-planted across the US for its uniform shape and dense flowering. But as it ages, the tree can literally split in half as weak branch attachments fail. A highly fertile seed crop makes it very invasive, creating 'pear forests' in old fields.

Culture and Care:
Care Requirements - Prefers full sun in moist soil; tolerates wet and dry spells as well as polution. Adaptable to a range of soil pH. Easy to transplant in late winter or early spring. Zone 5-8(9)
Native Habitat - Species native to Korea, Japan, China. Cultivar selected in 1969 in Independence, KY
Diseases and Insects - Basically free of pests, although fireblight can sometimes be a problem in stressful conditions.
Strength - A broad overall form and wider branch angle gives a slightly stronger branch attachment in this cultivar compared to other cultivars.
Weakness - Over-planted across the US for its uniform shape and dense flowering. Branch attachment failure slightly less of a problem in this cultivar. A highly fertile seed crop makes it very invasive, creating 'pear forests' in old fields.
