The Double Knock Out Rose (Rosa 'Radtko')
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, has the same bloom cycle and is slightly more winter hardy. A shrub rose with a classic look and the toughness that you expect from a member of The Knock Out Family.
