Description
The Hydrangea macrophylla 'Red Ace' is a new variety of large leaf hydrangea that stands out for its bicolour flowers, deep pink edged with white, gathered in beautiful round flower heads on a particularly dark green foliage. Depending on the soil and exposure, the pink of the flowers will be paler or almost red. Original and modern, this variety tolerates slightly sunny exposures better and stands out in the garden but also on the terrace, planted in a large pot. It is a contemporary bush, of modest size, very floriferous and easy to grow. This hydrangea grows well in fertile soil, even slightly chalky.
The Hydrangea macrophylla 'Red Ace' is one of the many hybrids obtained by cross-breeding hardy species that belong to the Hydrangeaceae family, originating from China and Japan. It is a very recent variety. This bush shows a rather rounded and regular habit. It will reach on average 1.10m (3 ft 7 in) in all directions. In July-August, its small flowers with striking dimorphism bloom, forming round flower heads, of a good size. The flowers are bicolour, red to pink, edged with white. If the bush is grown in a sunny exposure, the flowers will be lighter. If, on the other hand, it grows in the shade, they will be red edged with white. The PH of the soil also influences their hue. Flowering is accompanied by dark green foliage in summer, marked with deep veins. The leaves are opposite, they reach a minimum of ten centimetres in length. They are single, ovate to elliptical, ending in a sharp point, and serrated. Hydrangeas can live at least 50 years.
The Red Ace hydrangea is a beautiful bush that stands out during twilight and exudes elegance in the sunlight. When paired with white or red hydrangeas, they complement each other well. The Red Ace variety thrives when exposed to an east or west-facing direction that is not too hot. They can be grown in open ground or containers, placed on terraces or near entrances.
Although these plants are not fans of limestone, they are not strictly ericaceous plants. You can pair them with fuchsias magellanica, annual impatiens, or plant spring flowering bulbs in front of their round silhouette. You can enjoy their sumptuous flowering in the garden or the house for a long time.
Note that the colour of the flowers of the hydrangeas macrophylla varies based on the pH of the soil. Traditionally, blue varieties turn pink in neutral or alkaline soil. To maintain a beautiful blue colour, mix ericaceous soil with your garden soil and add alum stone or aluminium sulphate (which can be found in slate) every year in spring.

Planting and care
To plant the Hydrangea macrophylla Red Ace, choose a spot with some shade and morning sun, like an east-facing wall or a northern location. Avoid cold and drying winds. The plant isn't particular about soil, but it grows better in limestone soil, which makes the flowers redder. Use deep, fresh, well-drained soil with some fertility, and add fertilizer before planting. If the soil is dry, plant the root ball at least 30-40 cm (11.8-15.7 in) away from the wall and add compost to keep it moist. This plant is very tough and can survive cold weather. Trim the faded flowers down to the first bud or the pair of buds below. Prune a quarter or a third of the oldest stems to promote new growth when the plant is mature. Do this every 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.
