Plant Features

The Knock Out™ Red Rose Plant is just one of the Knockout series that has been produced by breeder Tom Carruth. The 3-inch blossoms on this shrub rose are fire-engine red when the weather is cooler, remarkably changing to cherry red during the warmer months of summer. Even the foliage gets in on the show; the leaves are a dark, purplish green in the spring and summer, turning deep burgundy as the temperatures cool. This Rosa plant is drought-tolerant, resistant to blackspot and self-cleaning with amazingly tough and hardy blossoms and foliage.

Companion Planting: Clematis, Coreopsis, Phlox
