Berberis thunbergii 'Rose Glow’

Berberis thunbergii ‘Rose Glow’: Marble-Toned Drama in a Shrub

‘Rose Glow’ is a standout among barberries for its vivid marbling of rose-pink, soft silver, and deep burgundy across every leaf. The arching branches create a graceful vase-shaped silhouette, while the vibrant variegation intensifies through the growing season. Small yellow spring flowers are followed by bright red berries in fall, adding ornamental value well into the cooler months. Thorny, deer-resistant, and drought-tolerant once established, this cultivar is both visually arresting and low maintenance.

• Height: 120–150 cm (4–5 ft)
• Spread: 90–120 cm (3–4 ft)
• Flower Colour: Yellow (inconspicuous)
• Flowering Period: Late spring
• Foliage: Variegated burgundy, rose-pink, and silver; turns red-purple in fall
• Sunlight Requirements: Full sun to part shade (best colour in full sun)
• Soil Requirements: Well-drained; adaptable to a range of soil types

Uses and Benefits: Perfect as a focal shrub, hedge, or accent in mass plantings. ‘Rose Glow’ adds a splash of colour in foundation beds, mixed borders, or rock gardens. Its thorny stems make it ideal for barrier plantings, while its foliage provides stunning contrast against greens, golds, or blues in the garden. Highly deer resistant and urban-tolerant.

Care Instructions: Plant in full sun for the best leaf variegation. Tolerates poor soils and drought once established. Water regularly during establishment, then only during prolonged dry periods. Prune in late winter or early spring to shape or rejuvenate. Avoid excessive pruning, which can reduce variegation.

History: A cultivated form of Japanese barberry, ‘Rose Glow’ was selected for its unique leaf colour and has remained a popular choice for bold foliage contrast in both residential and commercial landscapes.

Final Thoughts: With its painterly foliage and durable habit, ‘Rose Glow’ is a four-season shrub that offers both protection and panache. It’s an ideal choice where bold colour and practical performance are equally important.
