Description
The Hydrangea macrophylla Star Gazer Blue is a variety that offers flat inflorescences with triple lavender-blue flowers, bordered with white, evolving to pink depending on the nature of the soil, on a compact and bushy vegetation. Its thick, impeccable, glossy green foliage and its small development make it an excellent subject for pots and Japanese-style flower beds, in partial shade and in a non-calcareous 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 family Hydrangeaceae, native to China and Japan. 'Star Gazer' is part of a series of cultivars selected for their hardiness and their ability to bloom both on the current year's wood, in autumn, and on one-year-old branches in early summer. This bush has a compact habit, as wide as it is tall, reaching 1.10 m (3 ft 7 in) in all directions. From June to September-October, these small fertile and sterile flowers, with striking dimorphism, form flat, very light inflorescences. They are composed of triple sterile florets, bicolour, whose shade varies depending on the soil, surrounding a head of fertile florets in the form of matching-coloured buds. These small triple florets, as if hand-painted, are bordered with white, but in a very subtle fading manner. The flowers then fade to beige or light brown, with 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, thick, deciduous foliage. The leaves are opposite, reaching a minimum length of about ten centimeters. They are simple, ovate to elliptical, with a pointed tip, and serrated. Hydrangeas can live for at least 50 years.
The Star Gazer Hydrangea has excellent hardiness. Hydrangeas are well known for brightening the north side of houses. This one will thrive in a non-scorching east or west exposure, in flower beds as well as hedges. This variety is particularly suitable for container cultivation, which can be placed on the terrace or near the entrance. Although these plants dislike limestone, they are not strictly heather plants. Pair them with bush fuchsias, annual impatiens, or plant spring-flowering bulbs in front of their round silhouette. Enjoy their magnificent flowering in the garden or in the house for a long time.
Note: The colour of the flowers of macrophylla hydrangeas varies depending on the soil pH. Traditionally blue varieties turn pink in neutral or alkaline soil. To maintain a beautiful blue colour, mix heather soil or blonde peat with your garden soil and apply aluminum sulfate (slate contains it) or alum stone every spring.

Planting and care
Plant the Star Gazer Blue macrophylla hydrangea in spring or early autumn, preferably in a slightly shaded position, for example against an east-facing wall, or even to the north. Protect it from cold and drying winds. It does not require acidic soil, but appreciates a deep, moist but well-drained, fairly fertile soil, possibly enriched with a good base fertilizer before planting. If the soil is dry at the base of the wall, place the root ball at least 30-40 cm (11.8-15.7 in) away from the base of the wall and incorporate a quantity of well-decomposed compost to better retain moisture in the soil. Very hardy, it can be planted in cold regions without fear. As for pruning, remove faded flowers on the first bud or on the pair of buds directly below. Cut back a quarter or a third of the oldest stems at the base when the plant is mature to encourage the formation of new shoots. Carry out this pruning every year during the months of March and 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.
