Additional Information

The Double Knock Out Rose is a compact, bushy plant that prolifically produces fragrant, double, cherry-red flowers from summer through fall. While this is a very low maintenance and disease resistant rose, good cultural practices are still advised. Avoid wetting the foliage when watering, place the plant in an area with good air circulation, and remove dead or diseased plant matter as soon as possible. Branches are covered with thorns, making pruning difficult.
