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.

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.
The best roses

I have purchased roses elsewhere prior years. They were ok, but your are so large and healthy and started to leaf out almost immediately! I am very impressed with health and quality. Will let you now how blooms are when they start!
