The Double Knock Out® Rose

Rosa 'Radtko'
PP#16202 CPBR#3104

From the same cross that produced the original Knock Out®, The Double Knock Out® Rose represents the next generation in the family of The Knock Out® Roses. 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.
