Description / Double Knock Out® Shrub Rose

Several years ago, Knock Out® wowed gardeners everywhere with its superb performance as a landscape rose. Double Knock Out® Shrub Rose is not only a tireless bloomer, all summer and into fall, but also terrifically resistant to blackspot and other diseases, keeping Double Knock Out® Shrub Rose healthy foliage in any climate. The same breeder has developed Double Knock Out® Shrub Rose, with the same disease resistance, floriferousness, and fine landscape value—plus even greater shade tolerance and DOUBLE-flowered blooms.

These blooms of shiny cherry red are about 2½ inches wide and utterly unstoppable from early summer till frost. Most are fully double, some semi-double, with an average petal count of 18 to 24. These blooms are all high centered in the classic rose form. No need to deadhead this lively shrub— the flowers just keep coming no matter what.

A bit tighter, denser, and more compact than its famous sister, Double Knock Out® Shrub Rose makes a fine low hedge in any sunny to partly shaded garden. Double Knock Out® Shrub Rose also works well when planted as a long ribbon of color through a border.

A great deal of Double Knock Out® Shrub Rose value as a landscape rose comes from its 3-season appeal and its resistance to blackspot. Not only is the bloom season exceptionally long, but the foliage takes on rich burgundy hues when it emerges in spring, adding another season of color to this shrub's merits.

Crown-hardy to -20 degrees Fahrenheit, this 3- to 4-foot high and wide perennial withstands drought, heat, humidity and, in addition to blackspot, pests such as the Japanese beetle, leafhopper, and rose midge. Double Knock Out® Shrub Rose is a landscape treasure you must not miss.
