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 very light, fragrant flowers come in many colors and will bloom from spring until frost. Humidity doesn’t seem to bother the Knock Out® Rose, and it’s drought and cold tolerant. It’s somewhat shade-tolerant but does need 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 movement. Plant 48” apart.
