Rosa Red Knock Out®

The Knockout® 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 Knockout 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 Knockout 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. 

Height: 3-5 ft
