Knock Out and Carpet are trademarked names of two different families of roses that are formulated to be easy to grow and require little maintenance.
Knock Out roses were developed by Bill Radler and are sold by the Conard-Pyle Company. Carpet roses were developed by Noack Rosen and sold by Anthony Tesselaar Plants Pty. Ltd.
Knock Out roses are a shrub rose that grows approximately 3 to 4 feet tall, while Carpet roses are a ground cover rose. Both are 3 to 4 feet wide.
Both roses are maintenance-free. They do not require deadheading or pruning, though you can if choose to control growth. They are formulated to be disease resistant and tolerant of drought.
Both roses will grow well in zones 5 through 10 and may be used in colder climates with appropriate winter protection.
The Carpet rose is available in the following colors: amber, appleblossom, coral, yellow, pink, pink supreme, red, scarlet and white. Knock Out roses are under seven different names: Knock Out (cherry red single bloom), Double Knock Out (cherry red double bloom), Pink Knock Out (pink single bloom), Pink Double Knock Out (pink double bloom), Rainbow Knock Out (pink with yellow center), Blushing Knock Out (light pink), and Sunny Knock Out (yellow).
