Double Knock Out® Rose (Rosa ‘Radtko’) in the G2 size offers the same nonstop cherry-red blooms and exceptional disease resistance as the larger G3. Its self-cleaning flowers keep the plant looking fresh without deadheading, while its compact habit makes it perfect for borders, foundation plantings, and containers. Tough, colorful, and low-maintenance, it remains one of the most reliable roses for full-sun landscapes.
