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

StarÂ® Roses and Plants is proud to have introduced all seven members of The Knock OutÂ® Family of Roses. The Knock OutÂ® Family of Roses are easy to grow and don't require special care. Plant them individually among shrubs, annuals and perennials in mixed beds and borders. Plant them in large groups to create a colorful hedge or along a foundation to provide a bright border.
