By the way, if this tidbit of info helps any, as of 1990, Indianapolis was in plant zone 5b, now, as of the new 2012 map, it lists Indianapolis as a zone 6a hardiness zone wise.

I've had them for nearly a decade here in SE Michigan. They do well enough to give me some blooms. I've had them die back to the roots several times because voles got in under the winter protection and stripped all of the bark, but they do come back and rather quickly.

Definitely worth trying where you are. The hardiest types I guess are Edith Bogue, Bracken's Brown Beauty, and Little Gem, which are the 3 I've tried. Don't see much difference between them, Edith is the least likely to brown out during the winter, but in all but the mildest winters, even with protection, I generally lose all of the foliage. But, they regrow very quickly, by late May you would never know they defoliated.
