Carefree, endless blooming, and durable are some words to describe the popular shrub roses in the Knock Out® series. These roses bloom for months on end, starting in late spring and continuing, uninterrupted until frost. Bright cherry-red petals are arranged in several layers making them look big and full. Dark glossy purplish-green foliage stays fresh and free of black spot and other foliar diseases. Minimal pruning needed. Knock Out® roses do best in moist, well-drained loamy soils in full sun to part shade. They also benefit from a layer of mulch and good air flow between roses.
