KNOCK OUT® was first introduced in 2000 and hailed a “breakthrough shrub rose” by the All–American Rose Selections because of its exceptional disease resistance and hardiness. It was one of three roses to win the prestigious AARS award for outstanding garden performance in 2000. The double–flowering form is outstanding as well.
