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.

Beautiful!
We're so happy with our purchase! We bought six of these and they've taken off with growing and producing flowers.
customer service
Very difficult to order using replacement certificates so I called customer service to order. I was asked for a code which was not on the website so the lady told me to call back when I found it! Eventually, I was able to order because SHE knew the product code. Bad experience but I hope the plant is worth it.
Knock Your Eyes Out With Double Knock Out Roses
Over the past 8 months, I've purchased several different plants from Fast Growing Trees. One of these plants was the Double Knock Out Roses. I planted them just three weeks ago and they are already rewarding my purchase with an explosion of blooms! All the rest of my purchases are also showing great signs of their happiness with their new homes!
The Rose's exploded
When I got the tree I was like what is this but I figured it wasn't ready and was asleep. A few months later it is beautiful. Look what it bloomed into. All the people complaining it's dead its not just give it a chance that's what I thought at first. The first picture actually had leaves but those all fell off and it did look dead. Then beauty a few months later. I'm in southern California.
All good thanks
