Beautiful! I planted these in a row with home run red and the red and white row of small shrubs they make frame my outside flowerbed beautifully .

I have run over my poor "White Out" rose three times now...knocking off bits each time and it still hasn't stopped blooming even for a moment!

I got seven of these this year to edge an area of a white garden. The first month or so they were pathetic - so bad I almost considered taking them out. Am I glad I didn't! They started to put on new growth at an amazing rate, and have bloomed non-stop since the spring. It's September now and they're still gorgeous. They are doing as well or better than my red knockouts. I believe they have bloomed even more. Highly recommend!
