Why We Love It

Non-Stop Double Blooms: Unlike older shrub roses, this variety features full, fluffy double flowers in a rich cherry-red. It blooms in continuous, heavy waves from early spring all the way until the first hard frost.

Virtually Maintenance-Free: Forget about tedious deadheading! This self-cleaning rose drops its spent flowers naturally and pushes out fresh buds all on its own, saving you hours of garden chores.

Superior Disease Resistance: Bred specifically to fight off the black spot and powdery mildew that plague traditional roses, its dark green foliage stays clean, glossy, and handsome all season long.

Extreme Weather Tough: This rugged shrub handles intense summer heat and cold winter climates with absolute ease, thriving across USDA hardiness zones 5–11.

Quick Care Tips

Sun: Thrives in full sun. To get the maximum number of cherry-red blooms and keep the plant vigorous, give it at least 6 hours of direct sunlight daily.

Soil: Highly adaptable! While it loves rich, well-draining soil, it is very forgiving and can handle a wide variety of ground conditions.

Water: Provide regular moisture during its first season to establish a deep, resilient root system. Once mature, it is remarkably drought-tolerant.

Pruning: Simply cut the shrub back by about one-third in early spring just as the leaf buds begin to swell. This quick haircut stimulates a massive flush of new, flower-bearing growth.
