For a quarter of a century, the Knock Out® Rose has revolutionized the gardening world with its stunning blooms, low-maintenance care, and season-long color. Since its debut in 2000, this exceptional rose has become a favorite among home gardeners, landscapers, and public gardens.
The Birth of a Garden Icon
The story of the Knock Out Rose begins with William Radler, a passionate rose breeder who set out to create a disease-resistant, easy-care rose that would thrive in different climates. His breakthrough resulted in a shrub rose that was resistant to black spots and powdery mildew but also capable of blooming continuously from spring until the first frost.
When it was introduced to the market in 2000 by Star Roses and Plants, the gardening world took notice. Almost instantly, the Knock Out Rose became one of the best-selling roses in North America.
