Knock Out®'s Color + Carefree Growth in Tree Form
Why Knock Out® Rose Trees?
An abundance of rich blooms, with no maintenance needed: Knock Out® Roses have set the standard for bloom color, size, and adaptability. Now, horticulturists have bred a tree with the same characteristics.
The Knock Out® Rose Tree has raised the bar for disease resistance, and it's as carefree as they come. It's not susceptible to common rose diseases like black spot and mildew. Hardy and reliable, your rose tree will bloom from early spring to the first frost, giving you fluorescent blooms for months.
Plus, this tree form version of your favorite rose means versatility. The Knock Out® Rose Tree can be container planted to place beside entryways, on porches and even indoors if temperatures drop. No matter where you place it, though, it's a unique showcase plant that will set your homescape apart.
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
Your Knock Out® Rose Trees come pruned to promote more branching. More branching means more blooms!

Love my Knock Out Rose Tree
Fantastic, I love the Knock Out Rose Tree! I planted it near my garden patio and it brings so much color and warmth to my garden!
More Roses than you can IMAGINE
I ordered 2 knock out Rose trees in the beginning of August 2025 received them within 10 days. Followed the planting instructions to a tee and they have done remarkably well. See pictures of plants that were put in about 8/15/2025.
Knock Out Rose Tree
Loving my new rose tree. Came shipped as shown in my photos. Planted the next day after receiving. It’s doing great even in this dry summer heat.
The roses are mini roses
The roses are mini roses but beautiful. They do not look like you picture but still I love them.
Real beauties
