Rosa – Knock Out® Series
One of the most dependable landscape roses available, Double Knock Out® Rose produces waves of shiny red blooms from late spring through fall. Most flowers are fully double, with 18–25 petals, though occasional semi-double blooms add natural variation. New foliage emerges with a rich burgundy tint before maturing to deep green, adding early-season interest.
Highly disease resistant and own-root for improved hardiness, Double Knock Out® delivers continuous color with minimal maintenance.
