By far the most floriferous Knock Out®.

Plant Patent #17,346.

cv: 'RADcor.' The Knock Out® series just keeps getting better, and Rainbow Knock Out® is without a doubt its greatest star yet. It is the most floriferous Knock Out® (by far) and very disease resistant, with almost complete resistance to blackspot, powdery mildew, and rust. It reblooms ceaselessly from spring through fall in most climates, with lovely single blooms that change colors as they mature. It is even lightly scented, unlike most shrub Roses. What more could any Rose lover ask? This was named one of "The Easiest Roses You Can Grow" by Better Homes and Gardens, thanks to its famous disease resistance as well as its "cute, coral pink blooms"!

The blooms on this rounded, bushy 3- to 4-foot shrub open orange from coral-pink buds, then quickly turn a soft coral-pink shading to gold at the base, surrounding a yellow center. As they mature, they gradually turn light coral. Just 2 inches wide but packed with color and the scent of sweetbriar, they are a magnificent sight on a fully-blooming shrub, when the various colors of buds, new blooms, and mature flowers are present at once.

After the blooms finally pass, the shrub covers itself in bright orange hips that persist through winter, delighting the birds in your garden. This trouble-free, very high-performing and beautiful Rose makes an ideal hedge, driveway planting, ribbon of color in the perennial or shrub border, or container choice. Winner of a 2007 All-America Rose Selection Award, it is superior in every way. Zones 5-9.

Unusually pink, easy, and BIG HINT .....

This is gorgeous! It's still blooming because it's been so warm, though it began blooming IMMEDIATELY in the Spring. I did give it a bucket of water daily for a week, decreasing after and I kept it nicely watered. Every week I removed the dead buds and they removed quickly by hand with a little pull. This made it flower all over.

Good display roses

I am relatively new to garden but now have over 30 rose bushes. I have several knockouts. These bushes are very easy to maintain as far as disease and pests but as cutting roses...they make better display roses
Rainbow Knock Out is the best!

This hardy rose was everblooming in my zone 4/5 Alaskan garden. The yellow and pink blooms were a cheerful break from the usual mauve rugosas that are the norm in this area. Highly recommended

What to Expect
Container roses should typically be planted in late spring and fall. They’re easy to plant (all you need is a trowel), and they provide instant gratification, as they aren’t dormant and will have buds within a few short weeks, if they don’t when they arrive. They’re also perfect for transplanting into containers and make an attractive gift.

Container roses are usually nicely leafed out, and may even have flowers on them, which is a great way for you to know when you purchase them what they’re going to look and smell like.

Container-Grown Rose Instructions
  • When your roses arrive, water them thoroughly.
  • Choose a well-drained location that recieves at least 4 to 6 hours of direct sun each day. Dig a hole at least twice the size of the rootball. Mix the native soil with compost or other organic material and add superphosphates.
  • Gently loosen the rootball, place it into the hole so that the bud union sits 1 to 2 inches below soil level, and fill the hole with the remaining soil.
  • Water thoroughly, then mulch heavily around the base for winter protection. Your roses will arrive lightly pruned, so it is not imperative that you do any additional pruning before winter.
