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.

My trees arrived slightly dormant
My trees arrived slightly dormant already having thorns (I bought the 3-4ft trees) and they starting showing signs of leafing shortly thereafter. It appears they will grow just fine.

My New Favorite!!
My new Favorite Tree!! The roses are beautiful and they smell amazing!! When the blooms wilt, I would remove them and it wouldn't take much time before new blooms would appear. Love this tree and would highly recommend!
