Knock Out Roses

The Knock Out family redefined the landscape rose: disease-resistant, self-cleaning, and in bloom from spring to frost with almost no fuss.

Why Knock Out roses changed everything

Introduced in 2000 by breeder William Radler, the original Knock Out rose combined strong black-spot resistance with near-continuous bloom and required none of the spraying that older roses demanded. The series has since expanded to single and double forms in red, pink, coral, yellow, and white, plus a true miniature.

These are shrub roses bred for the landscape rather than the show table. They are self-cleaning, meaning spent flowers drop on their own, so deadheading is optional. For most gardeners they are the easiest roses to grow.

Quick tip: Once a year, in late winter, cut the whole plant back by about a third. That single hard prune keeps a Knock Out dense, tidy, and blooming hard all season.

Growing Knock Out roses

Plant in full sun in any reasonable, well-drained soil. They tolerate heat, humidity, and neglect better than almost any other rose, and are hardy through USDA zones 5 to 11. A single spring feeding is all most plants need.
