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.

Rose tree
Looks great, very healthy not going to plant it until it cools down a bit
Bloomed Beautifully
I purchased the knock out rose tree several weeks ago. It arrived on time and I planted it right away. After about 6 weeks the blooms began and now it carries many beautiful roses. The only advice I can give is about a week after receiving the tree the emails start coming wanting a review. At this time I had no blooms so I needed to wait, but like impatient children the requests for reviews continued even though I had no idea if it was going to live or not. Like everything you do in today’s world you will get nagged to review even before you know if you’ve made a good purchase, it’s ridiculous. I can now tell you it’s beautiful and I am very happy, I definitely would buy it again.
Gorgeous and healthy on delivery! So happy I found this website!

Ì was absolutely so impressed
Ì was absolutely so impressed by packaging, the height, how gorgeous they are. You’re my favorite company to order from in the future. I’m planning a larger project when temperatures cool down. Looking forward to ordering more from your company.
