Clethra alnifolia 'Ruby Spice' – Ruby Spice Summersweet

Ruby Spice summersweet ignites the late summer landscape with its spectacular spikes of deep pink flowers that hold their rich color without fading. This native shrub releases a heavenly, sweet fragrance that perfumes the entire garden just as other blooms begin to fade. It animates shaded corners and moist areas beautifully, thriving with vigour where few other plants can establish successfully.

Characteristics

• Foliage : The deciduous leaves emerge a lustrous dark green during the growing season before transforming into a brilliant golden yellow in autumn.
• Flowering / Fruiting / Stems : Long, dense, upright spikes of a rich, non-fading pink appear from late July through September. The flowers give way to small, decorative seed capsules that persist throughout the winter.
• Light : It tolerates full sun to full shade, offering exceptional versatility for dark garden areas.
• Habit : It deploys an upright, compact, and well-branched dense silhouette.
• Growth : Its moderate growth rate allows it to reach a mature height and spread of approximately 120 cm to 150 cm.
• Soil : It demands an acidic, organic-rich soil that remains consistently fresh to moist. It adapts easily to heavy clay soils and deficient drainage.
• Temperature : Its excellent hardiness corresponds to Canadian zone 4.
• Resistance : It withstands flooding, urban pollution, and salt spray admirably while demonstrating great immunity against major diseases.

Use

• Types of use : Integrate it into shrub borders, mixed flowerbeds, woodland gardens, or along the edges of water features. Its size fits perfectly for large container planting to brighten up a shaded patio.
• Decorative advantages : It provides an impeccable vertical structure, an explosion of late-season pink color, and a flamboyant autumn coloration that extends seasonal landscape interest.

Maintenance

• Watering : Water regularly to maintain a uniformly moist soil at all times, especially during summer heatwaves. Apply an organic mulch at the base to preserve root freshness.
• Fertilization : Spread rich compost or an fertilizer formulated for acid-loving plants early in the spring to support development.
• Pruning : Prune severely in late winter or early spring since flower buds develop on the new wood of the current year. Remove suckers if you wish to limit its spread.
• Planting : Maintain a spacing of 120 cm to 150 cm between plants to ensure a harmonious deployment.
