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.

Surpassed My Expectations
I was a little doubtful about the advertised characteristics of the Double Knock Out Roses. Because I have hardly ever had a problem with my selections I decided to give them a try. They are far exceeding my expectations! From the very beginning after I planted them in the ground, they were full of blossoms. They are a beautiful red rose and are abundant with buds all of the time. “Knock Out” is really a good name for these roses!!
So far I do. It
So far I do. It is dormant now. I will let u know when spring gets here

Great delivery and packing. Planted in zone 6. Arrived looking like an actual rose bush with flowers! It's about to get cold here, we will see. I will order from this company again.
