Sorry Sunflower I have to disagree.

China's in my experience are not very drought
or disease tolerant. Their twigginess can be a serious
maintenance problem. Oklahama City despite its Zone 7
classification occasionally get 0 F frosts.

This is a serious no no for a china. Anything below 20F
causes kill almost to the crown/ground line leaving you this
incredible tangled mess to clear.

A much better bet would be Buck roses. Some grow rather large
due to their laxa genes. Apple Jack in particular makes
a nice drought resistant, super tough 4' high shrub. There are
many others that perform similarly.

You can get Buck roses from those same stores.

If you are a true zone 7, then nothing beats the china roses for a hedge.
Archduke Charles combines the health of an ordinary woody ornamental (no
spraying whatsoever) with the twigginess of a good hedging plant, the
constant bloom of an annual, and the scent of spicy honey. You may want
to
winter protect them the first year until they become established, but the
chinas are also a lot more winter hardy than most books rate them to be.
Plenty of folks grow them in a solid zone 6 with minimal dieback. You can
get reasonably large plants from Chamblee's http://www.chambleeroses.com/
or
much larger (and more expensive plants) from the Antique Rose Emporium
http://www.antiqueroseemporium.com/ They also root rather easily,
allowing
you to perhaps purchase several plants to start your hedge and then you
can
make new plants of your own to extend it.
