Why Double Knock Out® Roses?
Boasting one of the longest blooming periods available, from early summer to late fall, the Double Knock Out® Rose gives you all the amazing characteristics of the original Knock Out® Rose - just with more petals and even better disease resistance.
Even better? Not only is this cultivar more resistant to black spot, rust, and mildew, but it's also more resistant to insects. That means the Double Knock Out® is virtually maintenance-free, especially since it grows thickly without pruning. Plus, it thrives in containers or in the ground.
About Knock Out® Roses: First introduced in 2000, the “Knock Out” family of roses has revolutionized the rose industry and remains the most prolific flowering shrub ever introduced. Each of the varieties in the brand are disease resistant, require minimal maintenance, and produce continuous blooms that last from spring to fall.

Roses are beautiful. Love the color
Very easy
Looked good, they are planted
Looked good, they are planted and I cleaned up the deadheads just above the 5 leave branch. Took a picture of then on 2 nd day planted. Thought I’d take pictures at 30 and 60 days then show you the progress
Great Costumer Service at Fast Growing Trees
I ordered a double knockout Rose which arrived very quickly but unfortunately was not in the best condition. I contacted FastGrowingTrees and they sent another one within a week, and it was in beautiful condition. Thank you Fast Growing Trees
