Knockout rose belongs to the genus Rosa. Knockout is a shrub rose that grows about 3 feet tall and wide, and stays in a relatively tidy mound. It produces terminal clusters of single, 3-inch diameter cherry red blooms. As long as it continues to grow through the summer, it will continue to bloom.
This shrub rose set a new standard in disease resistance with little to no maintenance required. The bloom cycle produces rich cherry red/hot pink blooms that will continue until the first hard frost. Black spot resistant, drought tolerant and self-cleaning, this rose suits every garden and every lifestyle.
