3-Gallon Knock Out Rose is a compact care-free deciduous shrub with serrated purplish-green foliage that turns purple to burgundy in fall. Fragrant clusters of large cherry red flowers bloom from late spring until the first frost, and are followed by orange-red rose hips. Best grown in full sun and rich, moist, slightly acidic well-drained soils. Knock Out is highly resistant to common rose diseases and drought tolerant.
