The Red Double Knock Out Rose has quickly become a favorite for gardeners all over the U.S. and beyond. From the same breed that created the original Knock Out Rose, the Double Knock Out packs twice the punch with twice the petals. Traditionally, each medium-sized bloom will range from 18-24 petals. From spring to fall, the Red Double Knock Out Rose produces velvety red double blooms that are deeply reminiscent of classic roses. These gorgeous blooms just keep on popping up for nearly the entire growing season and they're perfect for anyone looking for a truly reliable bloomer. Additionally, purplish-green foliage creates an attractive display even without blooms. Furthermore, Knock Outs are self-cleaning, meaning that there's no need to deadhead them, although you certainly can if you so desire.
