Knock Out roses were bred to be extremely resistant to diseases and drought, and if that wasnât enough, theyâre also repeat bloomers, bearing a new flush of flowers every five to six weeks from spring until the first hard frost. Theyâre heat-tolerant across most of the U.S. and cold tolerant to zone 5.
