Rosa hybrida ‘Radrazz’ PP #11836
For years, disease-resistant roses have been on the market, only to disappoint Southern gardeners. Now you’ll need to look no further.
The Knockout Red Rose has found its place in the hearts of American gardeners. Unlike its predecessors, Knockout Red has the grit to withstand our hot, humid weather.
This exciting rose cultivar is a shrub rose that grows about 3 feet tall and wide. As the weather warms, 3-inch diameter, cherry-red blooms appear as terminal clusters of single flowers. As long as the plants continue to grow through spring, summer, and fall, this rose will continue to flower.
Like nearly all roses, Knockout Red Rose performs best in full sun with fertile, well-drained soil. Prune during the growing season on an “as needed” basis to control plant size. Water during periods of drought to maintain a continual supply of flowers.
Chosen in 2000 as an All-America Rose Award winner, this plant is truly a knockout!
Site: Performs best with full sun and fertile, well-drained soil. Once established, may need additional water during periods of drought.
