The 'Sunny Knock Out' Rose is a compact and vigorous flowering shrub, renowned for its dazzling blooms and remarkable disease resistance. This bushy rose produces an abundance of bright yellow semi-double flowers that soften slightly to cream over a few days, creating a dynamic effect in mass plantings. Its dark green, dense, and glossy foliage highlights the continuous blooming from early summer until the first frosts. Ideal for borders, flowerbeds, or as a standalone plant, it attracts pollinators while requiring little maintenance. Very hardy and high-performing, the 'Sunny Knock Out' Rose is perfectly suited for northern gardens, bringing color, brightness, and lasting structure to sunny landscape designs.
