Why Sunny Knock Out® Rose Trees?
Setting the standard for carefree color and adaptability, the Knock Out® Rose Tree has raised the bar for disease resistance and carefree upkeep. It’s got all the hardy, reliable growth of the Knock Out® shrub in an even more versatile growth habit…and rich yellow blooms for up to nine months.
The Sunny 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 delivers reliability and masses of full yellow blooms without any effort on your part.
And the best part? This rose tree has everything you love about the Knock Out Rose family - including its full, consistent blooms, easy care and impressive disease and pest resistance.
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 FastGrowingTrees.com is Better

You'll enjoy instant impact for your yard and garden rather than waiting years to see results. Because your tree has been grafted and then nurtured for months before shipping, it leaves our nursery with a well-developed, healthy root system.
The Sunny Knock Out® is grafted with proven rootstock to combine the benefits of the Knock Out® shrub with a versatile, easy-growing tree form.
This is the hottest rose introduction in years. And these trees will sell out quickly, so order yours now!

Love mine
I love the contact from your company and shipping was better than I expected
Update
Follow up review… I pruned down to a basketball size of stems in February. I have added some liquid Miracle Grow every two weeks this year and the results are very positive. Photo taken late May 2026.
Beautiful tree
The rose tree arrived on time, looked quite good and delights us with its countless flowers. If it is properly cared for, it will beautify your garden.
So many Flowers!!
I bought 2 last year late in the year, they struggled a little bit. This year I bought a 3rd in March. Wow! All 3 are unbelievable now in April! The one I planted just a few weeks ago has so many flowers!! I did use some metal stakes and zip tied to each tree for wind stability. Worked excellent.
Beautiful tree so far
Arrived well packaged with buds popping out. Looks robust already. Can’t wait to see if it blooms this year.
