Knock Out roses were not created in a lab by horticulturalists or scientists, but by a passionate hobbyist named Will Radler. Radler discovered his love for roses at a young age, and after years of dedication and experimentation, he successfully bred ’89-20.1,’ which later came to be known as ‘Radrazz.’ Star Roses and Plants decided to take a chance on Radler’s creation, and it quickly became a massive success among gardeners.

Knock Out roses have revolutionized the way we view rose gardening. Unlike traditional roses, Knock Outs are low-maintenance, disease-resistant, and drought-tolerant.

Despite the criticism, Knock Out roses offer a beautiful and easy-to-grow option for your garden.
