Have grown this rose in Iowa in the 90's unprotected every winter. It reached 36" and preformed well in landscape. Moved to New Mexico in '97 planted 2 own root Amiga Mia's in 2000. We experience hardly any die back here in the Rio Grande valley. This rose is a 5 - 6 feet and have to heavily prune back each year-it is a show stopper. Would recommend anywhere
