Description
The Hydrangea macrophylla 'Star Gazer' is a beautiful novelty, offering compact, bushy vegetation with flat flower heads with porcelain hues. The sterile florets have a triple rank of diaphanous pink petals, or lavender blue, bordered by white, around a bouquet of pink or blue florets, depending on the nature of the soil. Its thick, flawless, glossy green foliage and small size make it an excellent subject for pots and Japanese-style flower beds in semi-shade and non-limestone soil.
Hydrangea macrophylla 'Star Gazer' is one of the many hybrids obtained by cross-breeding the species H. macrophylla and H. aspera, among others. All these plants belong to the Hydrangeaceae family, native to China and Japan. 'Star Gazer' is part of a series of cultivars selected for their hardiness and ability to flower on the year's wood in autumn and on one-year-old shoots in early summer. This bush shows a compact habit, as wide as it is high, 1.10 m (3 ft 7 in) in all directions. From June to September to October, these small fertile and sterile flowers, with striking dimorphism, form very light flat flower heads. They comprise triple sterile bicolour florets, whose hue varies depending on the soil. They surround a head of fertile florets in the shape of buttons in a matching colour. These small triple florets, as if hand-painted, are bordered by white but progressively in a highly subtle gradient. The flowers then fade to beige or light brown, in a texture reminiscent of paper. This variety will be more floriferous if care is taken to regularly remove faded flowers. The flowering is accompanied by dark green, shiny, thick, deciduous leaves. The leaves are opposite; they reach a minimum of ten centimetres in length. They are single, ovate to elliptical, ending in a pointed tip, saw-toothed. Hydrangeas can live at least 50 years.
The Kompeito Stargazer Hortensia has excellent hardiness. Hydrangeas are well known for brightening the north side of houses. This variety will thrive in an east or west exposure that is not burning in flower beds and hedges. This variety is particularly suitable for container cultivation, which can be positioned on the terrace or near the entrance. Even if these plants are not fond of limestone, they are not strictly ericaceous plants. Combine them with fuchsias magellanica, annual impatiens, or plant spring-flowering bulbs in front of their round silhouette. Enjoy their sumptuous and long-lasting flowering in the garden or the house.
Hydrangea macrophylla flowers come in different colours based on the soil pH level they are planted in. Blue flowers turn pink in neutral or alkaline soil. Add aluminium sulphate (found in slate) or alum stone to the soil every spring to keep the blue colour. You can also mix ericaceous compost with garden soil. This will help to maintain the blue colour.

Planting and care
To plant the hydrangea macrophylla 'Star Gazer', choose a slightly shaded spot in spring or early autumn, such as against an east-facing or northern wall. Keep it away from cold winds and the sun. It prefers deep, fresh, well-drained, and relatively fertile soil, but ericaceous soil is unnecessary. You can enrich the soil with a good base fertiliser before planting. If the soil is dry at the foot of the wall, plant the root ball at least 30-40 cm (11.8-15.7 in) away from the base and add well-rotted compost to improve soil freshness. This plant is resilient and can be planted in cold areas. When pruning, remove the faded flowers on the first or second bud. To encourage the formation of young shoots, cut back a quarter or a third of the oldest stems to the base when the plant matures. Prune every year in March or April.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
