Protected Series: KNOCK OUT
Zone: 4KNOCK OUT® RED SHRUB ROSE
Rosa Knock Out® Red is the rose that revolutionized the rose world, proving that a rose could be as tough and easy-to-grow as any common landscape shrub. This original member of the Knock Out® series produces a nearly non-stop display of vibrant, cherry-red single flowers. Each blossom is accented by a bright yellow center, creating a classic, cheery look that remains consistent from late spring all the way through the first hard frost.
The ideal spot for Knock Out® Red is a location with full sun and well-drained soil. It has a vigorous, bushy, and well-branched habit, typically maturing to about 3-4 feet in height and width. Its reliable performance and uniform shape make it a "go-to" choice for creating colorful low hedges, mass plantings, or high-impact foundation groupings. The foliage is a deep, dark green with a subtle burgundy sheen on the new growth, providing a rich, clean backdrop for the bold red flowers.
Renowned for its extreme hardiness, Red Knock Out® is exceptionally resistant to black spot and powdery mildew, meaning it stays lush and full without the need for regular spraying. It is also "self-cleaning," so the spent petals drop away naturally, allowing the plant to focus its energy on producing new buds rather than seeds.

To help this plant settle in and thrive, we recommend these standard planting practices: Plant in a location with at least 6 hours of direct sunlight. Ensure soil is well-draining. Water at the base (avoid getting leaves wet) to prevent fungal diseases. Prune in early spring. These are 'low-maintenance' roses. You can prune individually to shape, or, for large-scale mass plantings, you can use power shears to trim them back by one-third to encourage a flush of new, vigorous growth and continuous blooms.
