Odd. My Angel Face, whom of which I bought at a grocery store, has done magnificently here with almost minimal protection (less than 2" of mulch). And I planted her around the stump of my aspen with some of my other blue roses. She's between a Blue Girl & Melody Parfume. I bought her.. 4? years ago? Of course she doesn't get much taller than 2', but very few of my roses do!
