Rose Rainbow Knock Out® Shrub
Resistant to blackspot, powdery mildew, and rust -- no wonder it can bloom so heavily and long!
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?
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 5-10.

Easy as 1-2-3
Anyone can grow roses - all that's needed is a spot with 6 hours of sun a day. Roses are even well suited to container growing, so you don't have the excuse of no garden space!
Here's all there is to it!
STEP 1 - When your roses arrive, open the box immediately and soak roots in lukewarm water for 12 to 24 hours. If you can't plant them right away, you may leave them in their boxes for up to a week in a cool, dark place. Sprinkle roots with water every few days. (Please note: You can also grow roses in containers that are at least as big as a bucket.)
STEP 2 - Dig a hole about 18" deep and 24" wide. Make sure it's large enough to give the roots plenty of room to develop after planting. Loosen the soil at the bottom and sides. Build a mound in the center of the hole and set rose on top. For vigorous growth, abundant blooms and lush foliage, try adding J&P's Root Boost
STEP 3 - Fill the hole with two thirds of the remaining soil. Add water, let it soak in, then finish filling the hole. Tamp down lightly to remove air pockets and water well. Spread mulch around the plant to suppress weeds and retain moisture. Water 3-4 times a week until leaves begin to grow, weekly thereafter.

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.
