Rosa 'White Knock Out'
The White Knock Out® Rose is a hardy, easy-care shrub rose that produces pure white, lightly fragrant blooms from late spring until frost. It grows in a rounded, bushy form about 3 to 4 feet tall and wide, making it ideal for borders, foundation plantings, or mass plantings. Like others in the Knock Out® series, it’s highly resistant to black spot and mildew, with self-cleaning flowers and glossy, dark green foliage. Best grown in full sun and well-drained soil, it’s hardy in USDA zones 5 to 11 and offers reliable, long-lasting color with minimal maintenance.
