Colorful and tireless, the 'Knock Out Rainbow' rose offers a continuous bloom of single coral-pink flowers with a luminous golden center, creating a spectacular two-tone effect. Like all roses in the Knock Out series, it blooms continuously from spring until frost, without the need for pruning. Its well-branched, bushy habit, reaching 90 to 120 cm in height, is perfect for dynamic beds, flowering hedges, or repeat plantings. It has dark green, semi-glossy foliage, is very resistant to disease, and tolerates heat, drought, and urban pollution well. 'Rainbow Knock Out' is ideal for gardeners seeking bright color and minimal maintenance, with a guaranteed "wow" effect all season long.
