Description: The fire-engine-red double blooms of Rosa Double Knock Out keep coming until hard frost, and its new growth is a stunning burgundy red. Aptly named, this popular successor to Knock Out is fuller and more floriferous, producing clusters of 2 1/2in, incandescent blooms with 18-25 petals. A hardy variety naturally resistant to black spot and other diseases and pests. Own-root. ‘Radtko’ (PP 16,202).
