The Double Knock Out® Rose

Rosa ‘Radtko’ PP16202
From the same cross that produced the original Knock Out® Rose, this represents the next generation in the Knock Out® family. The full double flowers look just like a classic rose. What it gained in beauty it did not lose in performance. It is as resistant to black spot as the famous original and is slightly more winter hardy.

3-4' tall x 3-4' wide

Full sun
