Orange Glow Knock Out Rose

Rosa ‘Radslam’

Orange Glow Knock Out Rose is a vibrant landscape rose prized for its glowing orange-coral blooms, nonstop flowering, and exceptional disease resistance. From spring through frost, it produces abundant clusters of bright orange flowers with warm coral and peach undertones that create a bold, sunset-inspired display in the landscape. The blooms gradually soften in tone as they age, giving the plant a multicolored effect throughout the season.

This compact, rounded shrub typically reaches 3 to 4 feet tall and wide, forming a dense habit covered in glossy deep green foliage. The rich foliage provides beautiful contrast to the warm-toned blooms and remains clean and attractive thanks to the variety’s excellent resistance to common rose diseases such as black spot and powdery mildew.

Orange Glow Knock Out Rose is especially valued for combining dramatic color with the easy-care durability that Knock Out roses are known for. Unlike many traditional roses that require extensive maintenance, spraying, and deadheading, this variety blooms continuously with minimal effort. Its self-cleaning flowers help the plant maintain a fresh appearance without constant grooming.

Care Instructions:

Planting: Plant in full sun with good airflow for the strongest flowering and disease resistance.
Soil: Use fertile, well-drained soil enriched with organic matter.
Watering: Water regularly during establishment. Roses are moderately drought-tolerant once established.
Fertilizing: Feed in spring and midsummer with a balanced rose fertilizer if needed.
Pruning: Prune in late winter or early spring to shape and promote vigorous flowering.
Spacing: Space plants 3–4 ft apart for mature growth and airflow.
Maintenance: Deadheading is not required for repeat blooming.

This rose thrives in full sun and prefers fertile, well-drained soil with regular watering during establishment. Once established, it tolerates heat, humidity, and periods of drought extremely well while continuing to bloom heavily throughout the growing season. Pruning in late winter or early spring helps encourage vigorous growth and abundant flowering.

Its glowing orange blooms, reliable reblooming habit, and low-maintenance performance make Orange Glow Knock Out Rose an outstanding choice for adding bold season-long color to borders, foundation plantings, and mass landscape displays.
