(Rose) 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. Plant in Rose gardens, borders, or mixed in a perennial garden. The Knock Out® Family of Roses are easy to grow and do not require special care. They are the most disease resistant roses on the market. They have stunning flower power with a generous bloom cycle (about every 5-6 weeks) that will continue until the first hard frost. All of the Knock Out® Roses are self-cleaning so there is no need to deadhead. Patent Strings: Double Knock Out® Rose Rosa Hybrid 'RADtko' PP16202
