Double Knock Out® Rose

Double Knock Out® Rose is a dependable landscape shrub covered with full cherry-red double flowers from spring until frost. Deep purplish-green foliage gives the blooms a rich backdrop, and the naturally rounded habit fits easily into foundations, borders, flowering hedges, and mass plantings. It is prized for abundant flowering and strong disease resistance without routine deadheading. Plant in full sun and well-drained soil, with regular water while establishing.
