Double Knock Out® Shrub Rose
Even more compact and shade-tolerant than Knock Out®, it's ideal as a low hedge!
These blooms of shiny fire-engine red are about 2 1/2 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 25. 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, more dense and compact than its famous sister, Double Knock Out® makes a fine low hedge in any sunny to partly shaded garden. It also works well when planted as a long ribbon of color through a border.
A great deal of Double Knock Out's® value as a landscape Rose comes from its four-season appeal and its resistance to blackspot, that scourge of other Roses! 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 F, this 3- by 3-foot shrub withstands drought, heat, humidity and, in addition to blackspot, pests such as the Japanese beetle, leafhopper, and rose midge. A landscape treasure you must not miss! And now there's another member of the Knock Out family -- extra-long-blooming Pink! Zones 4-9.
