Red Knock Out Rose Bushes for Sale Online

The original member of The Knock Out® Family. The red knockout rose sets a new standard in black-spot resistance with little to no maintenance required.

The flowers are a rich cherry red color produced continually from late spring until the first hard frost. One of the first black spot-resistant roses, they are also drought-tolerant and self-cleaning, so you won't need to endlessly dead-head the spent blooms to keep the rose blooming.
