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.

Healthy and Beautiful
I ordered two earlier this spring. Loved them so these are our second two. All four are healthy and have beautiful blooms.
We love our double knock out roses
We bought 10 of the 7 gallon double knock out roses. They arrived a little beat up from shipping with the petals off. We dead headed and planted them and they are slowly coming around. We can't wait to see them flourish.
Honestly, I was a little
Honestly, I was a little concerned as the plants did not look healthy when I first got them, but I pulled him out gave him some water and some sunlight and got them in the ground fairly quickly and they are doing better. I like the color and I think they will do well Thank you.
Roses are not blooming yet but look healthy
Great. Have used before and will do again
Retraction
I recently placed a negative review that was premature. I apologize for my reaction to plants that arrived with issues. Fast Growing Trees responded with exceptional customer service replacing the plants within days. This is a very good company to deal with and extremely responsive in the event of any issues.
