Why Sunny Knock Out® Rose Trees?

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.

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.

Rose tree
Arrived pretty bedraggled, but we planted, mulched and watered. Have been watching carefully and watering due to heat. Looking forward to enjoying
Just ok
Not as full as the picture. Maybe in a few years.
Exceeds expectations
Another great purchase. Bought this little, beauty last year. It arrived healthy and blooming. I waited until this year to see what would happen. Well, I'm pleased to say it exceeded my expectations. It came back bigger and better with many roses. Just like described, yellow to a cream color. I love this tree more than I thought I would.
Yellow rose tree
Arrived much smaller than it appears in the ad picture (that's to be expected). It's now shedding leaves. Hoping to start seeing new leaves soon. Too early to rate. Let's see how it goes.
Shorter than expected but all
Shorter than expected but all three were same height and growing
