Undoubtedly one of the worst possible trees to plant. It is so weak limbed, and it self-seeds more than anyone wants (except possibly a grower of these awful and dangerous trees). Possibly thought of as beautiful in bloom in spring, but hardly worth the worry and concern. On a windy day I'd never let my grandchildren near it, and now that the tree is history, thanks to a storm, I no longer garden with creaking limbs over my head, never knowing whether the EMS would have to be called to try to revive me.

Aristocrat was lost during storm, Irene, in late August 2011, not 2010 as I stated previously.

I planted two Aristocrat Callery Pear trees in a big parking lot island in northeast Illinois in 1989. They looked fine in that tough location. About 2005 the hospital completely redid that area and all is gone. This cultivar was more pyramidal with wider branch crotches, (and wavy leaf margins and thornless) than most, but still was susceptible like other cultivars of this species to storm breakage. In the South it often was hit hard by Fireblight Disease. 'Aristocrat' has mostly been discontinued by the nursery industry. I don't recommend Callery Pear as a good ornamental tree for regular yards and landscapes. The birds will eat the tiny brown pears and spread them into the wild where it becomes a horrible invasive plant with sharp branchlets.
