Hydrangea macrophylla 'Ripple' - hortensie cu flori spectaculoase si frunze rosii

Hydrangea macrophylla 'Ripple' , also known as " Hydrangea Hovaria® Ripple" , is a spectacular cultivar of the species Hydrangea macrophylla, belonging to the Hydrangeaceae family. Part of the Hovaria® series, developed for its distinctive beauty, this hydrangea is appreciated for its bicolor inflorescences, with white flowers edged with vibrant red, and for its robustness. It is ideal for gardens, borders, terraces, pots or even as an indoor plant, bringing elegance and contrast to any space.

Appearance of leaves, flowers and fruits

• Leaves : The leaves are ovate or elliptical, with serrated edges, 15-20 cm long, initially red, but then turn a dark, glossy green. In autumn, they can again acquire copper-reddish shades, especially in the case of specimens exposed to the sun. The dense foliage provides an attractive background for the flowers. The new shoots are also red at first.
• Flowers : The flowers are spectacular, grouped in hemispherical inflorescences (mophead), 15-25 cm in diameter. The color can be influenced by the pH of the soil. The color distribution is bicolor and margined , due to the anthocyanin pigments concentrated at the edge of the petals, creating a dramatic visual effect. Flowering occurs from June to August , sometimes extending into September-October.
• Fruit: Produces small, dry capsules containing seeds, but these have no ornamental value and are rarely used for propagation due to the hybrid nature of the cultivar.

Growth characteristics

• Height and width : Grows to 1-1.2 m tall and 1-1.5 m wide in the garden, but remains more compact in pots ( 30-40 cm tall ). Annual growth is about 30-40 cm .
• Vigor : Moderately fast growth, forming a compact, rounded shrub with sturdy stems that support the large inflorescences well.
• Type : Deciduous shrub (loses its leaves in winter), grown as an ornamental plant for gardens, patios or indoors. It is resistant to salty winds, making it suitable for coastal gardens.

Growing conditions

• Exposure : Prefers semi-shade or partial shade , but will tolerate full sun if the soil is well-drained. In full sun, the flowers may fade and the leaves may burn in hot climates.
• Soil : Grows in moist, well-drained soils, preferably slightly acidic (pH 4.5-6.5) for more intense colors, but also tolerates neutral (pH 6.5-7.5) or alkaline (pH > 7.5) soils, which favor pink-reddish shades. Rich, humus-rich soils are ideal. In pots, use potting soil or acidic soil for hydrangeas.
• Watering : Requires regular watering, keeping the soil constantly moist but not waterlogged. Use lime-free water (preferably rainwater) to avoid alkalizing the soil. In pots, water frequently, especially in summer.
• Temperature : Hardy in zones 6-9 (down to -20°C), with good cold tolerance if roots are protected. In very cold climates, mulch the base of the plant in winter.

Care and resistance

• Resistance : Tolerant to salty winds, light drought (once established), and most pests. May attract aphids , mites , or slugs ; use insecticidal soap for control. Susceptible to root rot in poorly drained soils and chlorosis (yellowing of leaves) in overly alkaline soils.
• Fertilizer : Apply a fertilizer for hydrangeas or rhododendrons in spring and summer, every 2-4 weeks. To intensify the colors, use aluminum sulfate ("blue hydrangea") in acidic soils.
• Pruning : Cut back faded flowers and dead branches in early spring (March-April) to a pair of healthy buds. For rejuvenation, remove 1/3 of the old branches (light wood) up to 10 cm from the ground. Avoid excessive pruning, as it blooms on old wood.
• Propagation : Propagate by semi-woody stem cuttings in summer or by layering . Seeds are not viable due to the hybrid nature.

Hydrangea macrophylla 'Ripple' is ideal for ornamental gardens , borders , pots or as a solitary specimen . The bicolor inflorescences are perfect for fresh or dried floral arrangements. It combines well with other shade plants, such as hostas, ferns or azaleas, and is suitable for coastal gardens due to its tolerance to salty winds. It attracts bees and butterflies , contributing to biodiversity.

Origin

Hydrangea macrophylla is native to Japan , where it grows in coastal habitats. The 'Ripple' hydrangea cultivar is part of the Hovaria® series, developed for its bicolor flowers and hardiness. Introduced in the early 21st century, it is prized in Europe and the US for its unique aesthetics and adaptability.
