I received a very beautiful plant full of buds. I think it will be pink because of my soil, so much the better, that's what I wanted. Very satisfied.

Description
Hydrangea serrata 'Koreana' is a small hydrangea with a unique appearance, resembling a large flowering cushion. It deserves a place in our gardens. Slightly suckering, this bush spreads. It is particularly floriferous between the end of spring and summer and its foliage ignites in autumn. Like all Hydrangea serrata, this variety produces flattened inflorescences whose colour changes depending on the nature of the soil. Of modest stature, it is suitable for gardens of all sizes and works wonders in a large border or at the forefront of a bed, in semi-shade.
Originating from Japan and Korea, Hydrangea serrata are very hardy mountainous plants, belonging to the Hydrangeaceae family.
Hydrangea serrata 'Koreana' forms a low, round bush, reaching about 50 to 60cm (20 to 24in) in height and 1 to 1.3m (3 to 4ft) in width, sometimes more depending on growing conditions. Flowering extends from the end of May to July. It takes the form of numerous flattened inflorescences, 6 to 10cm (2 to 4in) in diameter, composed of tiny vaporous fertile flowers, pink in neutral soil or bluish-purple in acidic soil, and a crown of larger sterile florets whose colour matches. The stems and petioles of this hydrangea are tinted red. They bear leaves smaller and more ovate than those of Hydrangea macrophylla. The foliage develops red to burgundy tones at the end of the season. This hydrangea is deciduous and loses its leaves in winter. Hydrangeas can live for at least 50 years.
It prefers moist and acidic soils, and an exposure in semi-shade. It will charm with its wide cushion shape and its pretty colours. Hydrangeas are well known for brightening the north side of houses, and this one will be happy in an east or west exposure that is not burning, in a border or in front of taller bushes. This variety is well adapted to container cultivation, which can be placed on a terrace or near a doorway. Even though these plants dread limestone, hydrangea are not strictly ericaceous plants; they appreciate soils rich in organic matter. Combine them with shrubby fuchsias (Fuchsia magellanica) or hellebores, or plant bulbs with spring flowering in front of their round silhouette. Enjoy their sumptuous flowering in the garden or in the house for a long time.

Planting and care
Plant in spring or early autumn, preferably in a semi-shaded position, for example against an east-facing, or even north-facing wall. Keep it protected from cold and drying winds. It does not require ericaceous soil, but appreciates deep, cool, well-drained, fairly fertile soil, possibly enriched with a good base fertiliser before planting. If planting near a wall and the soil is dry at its base, place the root ball at least 30 to 40cm (12 to 16in) away from it and incorporate a quantity of well-decomposed compost to better retain moisture in the soil. Very hardy, it is not afraid to be planted in cold regions.
As for pruning, remove the faded flowers on the first bud or on the pair of buds directly below. When the plant is mature, prune the older stems back to the base by a quarter or a third. This will encourage the formation of young shoots. Carry out this pruning every year during 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).
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.
