On the plus side, this cultivar is vigorous and highly resistant to black spot and powdery mildew---it performs well without any fungicide here in black spot hell. Very floriferous, blooms almost continually through the season.

But I'm not fond of the flowers. They start looking ragged shortly after opening, and demand constant deadheading, as is common among white roses. They do not shed their brown petals quickly enough for my liking.

The New York Botanical Garden gives this rose a very high performance rating in its Peggy Rockefeller Rose Garden, where no fungicides are used.

This rose is considered hardy to Z4.

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!
