    Hardy little Rhodi for sure. We had temps down to -5 this winter with wind, and its site is somewhat exposed. No burnt out blooms and no brown leaves. It's blooming now and looks great. As the blooms age, it does lose some of that pink edging. New leaves are covered with white fuzz underneath, which fades to tan as they age. Very compact and only grows a couple of inches a year.
