‘Radwhite’ PP 20,273   We welcome to the Knockout Rose family a most exciting addition—the White Knockout Rose!  It has all the best qualities of the Knockout Rose series—abundant, repeating blooms throughout the growing season from spring to fall, manageable mature size without getting monstrous, and BEAUTY! Single white flat blooms contrast strikingly against dark green foliage, and the White Knockout Rose takes the prize for drought tolerance. It won the blue ribbon for outstanding, low-water performance in the 2017-2019 Water Use Classification of Landscape Series trials. Plant the White Knockout at the back of a sunny border, or try it against that hot brick wall you don’t know what to do with! For a more relaxed vibe, mix with Pugster butterfly bush, Drift rose, forsythia, lilac, and hibiscus for a show-stopping cottage garden.
