The Knock Out® Family of Roses
Star® Roses and Plants/Conard-Pyle is proud to have introduced all seven members of The Knock Out® Family of Roses. The Knock Out® Family of Roses are easy to grow and do not require special care. They are the most disease resistant roses 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 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. 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.

At Star® Roses and Plants, we are a family of brands, and we pride ourselves in being a one-stop-shop for our growers, their customers, landscapers, and home gardeners. Since 1897, we have dedicated ourselves to bringing great plants to the world’s gardens, and we aspire to continue doing so for years to come. Many notable roses, shrubs, and perennials have made it to market during this time, but one of the most impressive is The Knock Out® Family of Roses. Introduced in 2000, this family of extremely floriferous, low-maintenance, disease resistant shrub roses revolutionized the way we think of roses. The Petite Knock Out® Rose is the newest member of the family, offering the same desirable qualities but in a perfectly miniature size! 

Similarly impressive is our collection of groundcover roses, Drift® Roses, which offer a more compact solution to gardens of all sizes, and Sunblaze® Roses, which are a superb selection of vibrantly colored, miniature roses that are hardy, compact, and easy to grow.  

With more to offer than just roses, Star®?Roses and Plants also has breakthrough woodies, edibles, and trees. The Bloomables® collection is made up of our best flowering roses and woodies that are easy to grow for the grower and consumer, look good at retail and offer high reward in the garden. Also unique is the Bushel and Berry® collection of compact, self-pollinating, berry plants for the home garden. These blueberries, raspberries, blackberries, and now strawberries are easy to grow and easy to love! Our extensive woody program is distinct, as well, including notable Abelia, Buxus, Hydrangea, Hibiscus, and much more, and our breakthrough tree program offers highly unique, ground-breaking varieties that truly stand out in the landscape.     

At Star® Roses and Plants, we are committed to providing plants that are unique and versatile so that they satisfy a wide range of customers and landscapes. We always learn from the plants we trial, and as a result, we are proud to bring innovative plants and programs to market so that your gardening experience is just a little happier as a result.
