Rose Double Knock Out The cherry-red double blooms of Rosa Double Knock Out® keep coming until hard frost, and its new growth is a stunning burgundy red. Aptly named, this popular successor to Knock Out® is fuller and more floriferous, producing clusters of 2 1/2in, incandescent blooms with 18-25 petals. A hardy variety naturally resistant to black spot and other diseases and pests. Our rugged and heavy-blooming Shrub Roses are part of a new category called 'Landscape Roses.' The term means each of these plants is of such indomitable character it will thrive virtually unattended. Use multiples of the same variety to create superb hedges, ground covers, or foundation plantings; or give individual plants the prominent place they deserve in a mixed border.
