Rosa ‘Knock Out®’ is an iconic, low-maintenance shrub rose celebrated for its vibrant cherry-red blooms and exceptional disease resistance. Producing clusters of single to semi-dou ble flowers from spring until frost, it delivers continuous, long-lasting colour even in heat and challenging conditions. Its compact, bushy habit and deep purplish-green foliage create a striking contrast, with added seasonal interest as the leaves take on burgundy tones in fall. Drought-tolerant, self-cleaning, and easy to grow, ‘Knock Out®’ is a reliable choice for borders, mass plantings, or containers, offering effortless beauty and strong performance for gardeners of all experience levels.
