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

I just planted 3 of
I just planted 3 of the rose schrub bushes a month ago. Look healthy and have flowers. I’m very satisfied.
Great plants
3 Knock out rose bushes arrived quickly and perfectly boxed. I planted them the following day and they haven't stopped growing since then. It's been a couple of months and they've been in constant buds and blooms for over a month. 2 have doubled in size and the 3rd is close behind. They have a drip irrigation system keeping them hydrated and sailed through some record cold here in the midlands of SC. We've been very happy with the plants and trees from Fast Growing Trees and we'll definitely be ordering more in the fall. Great company.
Double knockout shrubs.
I have loved knockout roses in all forms. I’m excited to see how these two do. I planted 2 others earlier and they have done well.
Helpful resolution of packing issue
Good
My rose is red!
Item arrived in perfect condition, was placed in the ground a week ago and I have my first rose two days ago. All of my plants are very productive and looking great. Many thanks!
