Knock Out Roses

American gardeners love Knock Out Roses—and with good reason. These rose bushes produce loads of flowers from late spring to early fall. They have some of the longest bloom cycles among rose varieties. The free-flowering, showy blooms just keep pushing old flowers out of the way to make room for new ones. Suitable for zones 4-10, Knock Out Roses are low-maintenance plants with good disease resistance. They perform best in full sun to partial shade. Most Knock-Out Roses grow just 3-4 ft. tall, making them easy to grow in borders or as low hedges. Direct Gardening offers Knock Out Rose bushes for sale in several different colors.
