The Rainbow Knock Out Rose is one of the toughest of the tought line of knock out roses, with more disease resistance and climate hardiness than any Knock Out rose before it. The most disease-free yet, it is almost completely resistant to blackspot, powdery mildew, and rust. It’s a rebloomer from spring through fall in most climates, with lovely single blooms that change colors as they mature. It is even lightly scented, unlike most shrub Roses, so you get that old-time rose essence with a brand new low maintainence rose.
