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.
Why Fast-Growing-Trees.com is Better
With plenty of blooms to spare, you'll enjoy fresh cut roses in your home from spring until fall. And depending on your soil conditions, your blooms can range from dark to light red, offering even more versatility. And we prune your Knock Out® Roses before we ship them to give you an explosion of growth. Because of our hard work at the nursery and tried-and-true shipping process, you get a greater chance of success at home.

TOTALLY Knock Out Gorgeous
My rose bushes arrived well packaged. They were knocked around pretty good during shipping, but I got them in the ground and are thriving! They are definitely hearty. I am happy with this purchase.
Looking good
Hello. . the shrub looked weak when I received it, but began doing much better within a week. I’ve put it into a large planter and new growth is happening. No blooms yet but I’m not sure if I should expect them yet. First time buying a rose anything.

well packaged-arrived looking healthy-planted right away-so far so good-a bit soon to tell hpw it will do
Low maintenance, fast growing, and extreme weather tolerant
We planted these double knockout roses two years ago using the root boost and then fertilizing every few months. Our summers have been brutal, with long hot days exceeding 100 degrees. The winters have been just as extreme, with freezing temperatures sinking below 20 degrees. These roses remain hardy and deep green all year long and show off magnificent blooms most of the year. We couldn’t be happier with our purchase. These low maintenance roses are the highlight of our driveway and entrance landscaping.
