The Knock Out® Rose ranges from 3 to 5 feet tall and equally wide. It produces multiple clusters of terminal blooms, each 3 to 3.5 inches across. These lightly fragrant flowers come in many colors and bloom continuously from spring until frost. Humidity doesn’t bother the Knock Out® Rose, and it is both drought and cold tolerant. Somewhat shade-tolerant, it still requires about six hours of full sun per day. True to its low-maintenance reputation, the Knock Out® Rose doesn’t require deadheading and is resistant to aphids, powdery mildew, and black spot. Choose a well-drained site with good air circulation. Space plants 48 inches apart. PP#20273
