Yellow Blooms + Carefree Knock Out® Growth in Tree Form

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

Typical roses grow rather slowly and require lots of pruning, deadheading, and cleaning. But when you order your Sunny Knock Out® from Fast Growing Trees, you'll soon be rewarded with months of colorful blooms, without all the fuss.

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!

JUST PERFECT

Our family was unable to attend an out of state celebration of life for a very dear family last month. We wanted to send something to honor the loss of their mom, mother in law, grandmother who was a very special woman to our family for the past 4 generations. This was perfect! Thank you so much.

Fast Growing Trees Plant ExpertWhat a beautiful way to honor someone so special. We're truly grateful the Sunny Knock Out Rose Tree could help your family send that love and remembrance across the distance. Thank you for trusting us with something so meaningful.

Sunny Knockout Roses

Took a little time for them to really get established. We ended up having to move them to a different location and trim them back a little bit but they seem to be doing well now. Blooming a little bit. Fully yet. Pretty when they do. Do I need to keep deadheading them?

Fast Growing Trees Plant ExpertWe appreciate your wonderful review. It sounds like you did a fantastic job managing their transition. Moving a rose tree takes a little patience, but your decision to prune them back slightly gave them the perfect reset to start thriving in their new location. Regarding deadheading, you are actually in luck. The Sunny Knock Out® is a self-cleaning variety, so it does not strictly require you to remove old blossoms to keep blooming. That said, lightly shearing or deadheading the spent flowers can help the tree redirect its energy into fresh new buds even quicker. We are so glad to hear they are starting to put on a show for you. We're always here if you need any help!
