Protected Series: KNOCK OUT
Zone: 4KNOCK OUT® WHITE SHRUB ROSE
Rosa Knock Out® White is the quintessential choice for gardeners who want the classic, crisp look of a white rose without the high-maintenance reputation. White Knock Out® produces a constant supply of pure, snowy-white single blooms that stand out brilliantly against its very dark green, semi-glossy foliage. The contrast between the pristine white petals and the deep, lush leaves creates a sophisticated and clean aesthetic that works well in almost any landscape design.
The ideal spot for White Knock Out® rose is a sunny location with well-drained soil. It maintains a very tidy, rounded, and compact habit, typically reaching about 3 to 4 feet in height and width. This makes it an excellent selection for white-themed gardens ("moon gardens"), low hedges, or as a bright highlight in a mixed perennial border. Because the color is so neutral and clean, it is particularly effective at "popping" in the early evening light.
True to the Knock Out® name, Knock Out® White is "self-cleaning," meaning it will continue to push out new white blossoms from late spring until the first hard frost without any need for deadheading. It is exceptionally resistant to black spot and powdery mildew, ensuring the plant looks healthy and vibrant throughout the season.

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.
