Aristocrat Pear tree

[tguetz]

I need information on the Aristocrat Pear tree. Specifically, how tall
does it
get, does it have an invasive root system, is it native to Colorado or
how
does it survive in our climate, and how much water does it require.

Pyrus calleryana 'Aristocrat'
According to Sunset Western Garden Book, Callery Pears were natives of China -- yeah, right, like China varies its climate like the USA in that Colorado ain't much like Florida!

Anyway, considered much better structured than 'Bradford'. And, grows to 40' tall with 20' spread. Roots need enough water to keep them thriving, but generally short surface watering promotes shallow roots system -- monthly deep soaking (10 to 20 gallons per trunk diameter inch) minimizes surface roots around here.
