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.

Then double knockout rose bushes
Then double knockout rose bushes that we purchased are very nice and uniformed so they're going to look fabulous in front of the house
The roses arrived quickly and
The roses arrived quickly and in good shape (one actually had a bloom). So far so good!
Roses survived a few Knock Out punches in shipping!
Roses arrived fairly beat up from their travels, but all survived and are enjoying their new home in my yard. Thanks!
Still Blooming
The rose bush arrived quickly and in good condition. I put it in the ground in early September in upstate NY. We are now in mid October and the rose bush is still blooming. I’m excited to see how beautiful it will become as it continues to grow. Very happy with this purchase!
Amazing roses!
These roses are wonderful!
