The Knock Out® Family of Roses

Blooms from Spring until Frost. Easy to Grow. Low Maintenance. Great Disease Resistance.

The Conard-Pyle Co./Star® Roses is proud to have introduced all seven members of The Knock Out® Family of Roses.

Garden expert, P. Allen Smith shows just how easy it is to plant and care for The Knock Out® Family of Roses:

Rose Breeder, Bill Radler, has revolutionized the way we think of roses. With the creation of The Knock Out® Rose, many say that he single-handedly brought rose genetics from the 20th Century into the 21st Century.

The Knock Out® Rose, Radler's first commercial success and a 2000 AARS winner, has broken all records for sales of a new rose. Today The Knock Out® Rose is the most widely sold rose in North America.

The Knock Out® Family of Roses are easy to grow and do not require special care. They are the most disease resistant rose on the market. They have stunning flower power with a generous bloom cycle (about every 5-6 weeks) that will continue until the first hard frost. All of the Knock Out® Roses are self-cleaning so there is no need to deadhead.

The Knock Out® Family of Roses are winter hardy to USDA Zone 5 and heat tolerant throughout the entire U.S. They thrive in almost every area of the country. In the coldest regions, they will need winter protection.

If unpruned, The Knock Out® Family of Roses can easily grow to be more than 3-4' wide x 3-4' tall. Periodic trims will keep them maintained at a smaller size. A once a year cut (to about 12-18" above the ground) in early spring (after the last hard frost) is also recommended for maximum performance.

The Knock Out® Family of Roses can fit into any landscape. Plant them individually among shrubs, annuals and perennials in mixed beds and borders. Plant them in large groups to create a colorful hedge. Plant them along a foundation to provide a bright border. Want some more ideas? Check out our Knock Out® Family photo gallery to get inspired.

Research and development continues each year to find new members of The Knock Out® Family of Roses. To assure that these new introductions meet the standards set by the original Knock Out® rose, all test varieties are evaluated for several years in a wide variety of climates and growing conditions at locations around the country. Only a fraction of the test varieties will meet the Knock Out® standards and will be introduced.

The Knock Out® Family of Roses can be purchased at garden retailers throughout the country. Check with your local garden center to see if they carry what you're looking for or click here to find a garden retailer near you.
