Description
Hydrangea macrophylla Great Star 'Blanc Bleu' is a bush with a ball-shaped habit. In summer, a beautiful flowering appears on the shoots of the previous year. Large, flat inflorescences measuring 20cm (7.9in) are filled with a few sterile white flowers and numerous fertile flowers of blue or pink (depending on the acidity of the soil).
This hydrangea comes from seeds collected in Japan and was selected in Princess Sturdza's property. It was introduced by Minier Nurseries in 2007. Its leaves measure from 10 to 20cm (7.9in) in length. They are wide, ovate, and dentate. This beautiful foliage is dark green in colour. After about ten years, this variety can reach a height of 1.50m (4ft 11in) to 2.5m (8ft 2in).
It is a very hardy (-20°) bush. The Hydrangea macrophylla is suitable for flower beds.

Planting and care
Plant Hydrangea macrophylla in spring or early autumn, preferably in a slightly shaded position, for example against an east-facing wall, or even north-facing. Protect it from cold and drying winds. It does not require ericaceous soil, but it dislikes very chalky soils and appreciates a deep, moist but well-drained soil, fairly fertile, 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 30-40cm (11.8 - 15.7in) 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 older 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. Guide the young shoots onto the support to distribute them well. They will then attach themselves.

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).
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 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.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
