Hydrangea macrophylla 'Bubble Bath' – 'Bubble Bath' Hydrangea

The 'Bubble Bath' Hydrangea enchants gardens with its unique blooms featuring incurved petals that resemble delicate soap bubbles. Part of the Seaside Swirl® series, this variety stands out for its ability to rebloom on both old and new wood, ensuring a generous floral display from early summer through to fall. Its sturdy stems and compact habit make it an exceptional choice for adding a touch of softness and elegance to garden beds or large containers.

• Foliage: Displays large, glossy dark green leaves, providing a dense texture and the perfect backdrop for its blooms.
• Flowering / Fruit / Stems: Produces dense mophead flowers with cupped sepals. The colour shifts from soft pink to lavender-blue depending on soil acidity.
• Light: Prefers morning sun with protection from the harsh afternoon sun (partial shade).
• Habit: Features a rounded, upright, and compact form that does not flop under the weight of the flowers.
• Growth: Reaches a mature size of approximately 60 to 90 cm (24 to 36 inches) in height and width.
• Soil: Thrives in soil rich in organic matter that is perfectly drained. Acidity directly influences the flower shades.
• Temperature: Outstanding hardiness (Zone 3); significantly more cold-tolerant than traditional macrophylla varieties.
• Resistances: Strong resistance to common fungal issues such as powdery mildew.

• Types of use: Ideal for mass plantings, foundation borders, low hedges, or as a thriller in containers.
• Decorative advantages: Its sculpturally shaped flowers are stunning as cut flowers and maintain their beauty even when dried.

• Watering: Keep the soil uniformly moist, especially during hot spells. Mulching at the base helps retain moisture.
• Fertilization: Apply a flowering shrub fertilizer in early spring. Use a soil acidifier to achieve or maintain blue tones.
• Pruning: Lightly prune after flowering if necessary. Since it blooms on both old and new wood, avoid heavy pruning in the spring.
• Planting: Space plants approximately 90 cm (36 inches) apart to allow for proper air circulation.
• Winter Protection: Although extremely hardy, a layer of mulch at the base is recommended to protect the root system in variable climates.
