National Plant Network’s grower approved selections take the guesswork out of gardening! Red Double Knock Out is a vibrant shrub rose prized for its rich cherry-red double blooms. Flowering from late spring all the way to first frost, this hardy rose thrives in USDA zones 5 through 11 in full sun with well-drained soil, and tolerates drought once established. Use it for bold hedges, mass plantings, mixed beds or as a specimen where its continuous blooms and showy red color will make impact. Its strong disease resistance and tidy, self-cleaning habit make it low maintenance 'must have' for any garden!
