Additional Information

History and introduction of Knockout Roses:

When rosarian William Radler was a teenager, he resolved to breed a hardy rose that was beautiful, bloomed all season, was disease resistant, and maintained an attractive shrub like habit. He remains committed to breeding the "high-maintenance" issues out of his roses. He succeeded with his first introduction, Knock Out™, the award-winning shrub rose that mail-order catalogs call "perhaps the best-ever landscape rose for four-season interest." Mr. Radler germinated the first Knock Out seed in his basement during the winter of 1988–89, and that spring he planted the small shrub outside in his garden. The following 11 years were spent overseeing bud grafting, testing, and production of more stock. The rose was offered to the All America Rose Selections committee and declared a winner in 1997. Knock Out became available to the public with 250,000 plants in production. And a star was born. In 1992 a well known company known as Star Roses & Plants near Philadelphia signed a contract with Radler to begin testing on his new rose, a process which took eight years. With testing complete, the company filed for a patent and named the new, easy-care rose Knockout. Sales began in the year 2000.
