Double Knock Out® Rose
Shrub Pose
Rosa 'RADtko'
Plant Description
Double Knock Out® Rose offers the same outstanding performance as its sister, Knock Out®, but with fully double blooms for a fuller, more traditional rose look. Bright cherry-red flowers appear continuously throughout summer and drop cleanly when spent, keeping plants tidy. In fall, foliage deepens to an attractive purple tone for added seasonal interest. Highly disease resistant, hardy, and drought tolerant once established, this own-root rose is an excellent low-maintenance choice for modern landscapes.
