Celebrating 25 years of Knock Out roses

Star Roses and Plants announced its award-winning Knock Out rose is celebrating its 25th anniversary this year. First introduced in 2000, the Knock Out rose became known for its continuous bloom cycle, remarkable disease resistance and dazzling colors. Its low-maintenance nature set a new benchmark for flowering shrubs, earning it a reputation as a game-changer in the garden.

Breeder Will Radler’s early fascination with roses sparked a lifelong mission to create disease-resistant varieties. In 1992, Radler developed a seedling resistant to diseases, pests and extreme weather, transforming the rose market for decades. In 1992, Star Roses and Plants recognized its potential and, by 2000, the Knock Out rose had made its debut — ushering in a new era for rose gardening.

Some 25 years later, the Knock Out rose is one of the best-selling roses in North America, with a collection of 12 varieties, each known for beauty, adaptability and reliability.

“The Knock Out rose has become an icon in gardens and landscapes across the country,” said Brad Yoder, president at Star Roses and Plants. “Its ability to thrive with minimal care has made it a favorite among casual gardeners and professionals alike. Celebrating 25 years of success is a testament to its timeless appeal and extraordinary genetics.”

To celebrate this milestone, Star Roses and Plants invites gardeners to share their Knock Out rose stories on social media using the hashtag #KnockOut25.
