A 2000 AARS Winner that needs only half a day of sun!

Fire-engine red blooms and light Tea Rose fragrance pack a punch in the garden - even in part shade!

Plant Patent #11,836. Cultivar name: 'Radrazz'. Perhaps the best-ever landscape Rose for four-season interest, this stunning hybrid is the culmination of breeder William Radler's lifework. Not only is it the most blackspot-resistant Rose we've ever grown, but it also stands up to Japanese beetles and other pests, needs only half a day of sunshine, blooms over an exceptionally long period, and offers foliage and fruit interest as well as lovely blossoms.

Exceptionally hardy and disease resistant, Knock Out® is also breathtakingly beautiful, with great clusters of 3½-inch blooms of fire-engine red (or lighter cherry-scarlet in hot climes). These flowers begin early in Rose season and continue for many weeks. The shrub then rests for a bit and repeats for the remainder of summer and well into fall! It's one of the longest bloom cycles in the Rose family and will fill your garden with bright color and subtle tea scent. And when the blooms finally end, the color continues with burgundy-violet fall foliage and orange-red hips.

Crown hardy to -20?F, this 3- by 3-foot shrub sneers at drought, humidity, and pests such as blackspot, Japanese beetles, leafhoppers, and rose midge. It is essentially maintenance free, although like any new addition to your garden, it appreciates pampering the first season or two. Knock Out® was bred from a seedling of R. 'Carefree Beauty' x a seedling of R. 'Razzle Dazzle'. It has become so immensely popular since its introduction that new Knock Outs® are arising each season. We recommend Pink Knock Out® and Double Knock Out®.

Knock Out® never needs deadheading and is one of the very few Roses that earns the title "maintenance free." Zones 4-9.

Bareroot or Container?

World's Finest Roses

Have you browsed through your favorite gardening catalog or website looking for the newest roses to plant in your garden and wondered whether it would be best to choose bareroot roses or those in nursery pots? Or does it matter? If you’re like most rose gardeners, this question has come up at one point or another. And we want to help you find the answer as to what’s the best for you and your garden.

Bareroot Roses


Bareroot roses are an inexpensive and easy option for early-season planting. In fact, late winter is the best time to plant. Bareroot roses meet the highest industry standards. They arrive dormant, which makes them ideal for planting. The roots get to acclimate to native soil, as opposed to the packaged soil. And of course, since they aren't in soil when you get them, there’s no mess to contend with.

Bareroot roses may look dead, with their brown roots and dormant stem, but plants that arrive this way actually have the advantage of being able to focus their energies on strong root development rather than having to support an extensive growth of leaves during planting, which is very stressful.

You can plant your bareroot roses earlier in the growing season as well, since there aren't any leaves to get nipped back by frost. They can typically be planted as early as six weeks before your area’s last frost date in the spring. Since they don’t have to provide water to leaves or flowers, they usually establish quickly.


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 decorative 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. As you can see, there are advantages to both bareroot or container roses, so whichever you decide is the best for your garden, we feel certain you’ll become a lifelong rose lover, if you aren't already!

I planted your roses last fall and they took off immediately. They came to me very well packed and ready to plant. I plan on increasing my rose garden this next spring.
