Knock Out Double Red Rose

Rosa 'Radtko' PP16202 CPBR#3104

Rose Knockout Double Red is a standout shrub rose known for its rich, velvety red blooms and remarkable ease of care. Unlike traditional roses, this variety produces lush, double-petaled flowers that repeat continuously from spring through the first frost, without the need for intensive maintenance. Its naturally compact, rounded habit makes it ideal for garden borders, foundation plantings, mass landscapes, or as a bold standalone accent.

This rose is prized for its exceptional disease resistance, especially against black spot and powdery mildew, allowing it to maintain clean, healthy foliage throughout the growing season. The deep green leaves provide a striking contrast to the vibrant red blooms, enhancing visual appeal even when flowers are not in peak display. Rose Knockout Double Red thrives in a wide range of climates and is both heat and drought tolerant once established, making it a reliable choice for gardeners of all experience levels.

Whether you’re creating a formal garden design or a relaxed cottage-style landscape, this rose offers dependable performance and dramatic color with minimal effort. Its consistent flowering and resilience make it one of the most popular modern roses available today.
