Rose 'Knockout Double Red' is a deciduous landscape rose. Prolific double, rich red blooms appear non-stop from spring through frost with the same legendary disease resistance and self-cleaning habit that made the Knockout series famous. Thrives in full sun (6+ hours) with fertile, well-drained soil. These modern landscape roses are bred for exceptional disease resistance and require little to no spraying. An outstanding choice for borders, mass plantings, slopes, and groundcover where season-long color and low maintenance are both desired.
