Description
Hydrangea paniculata 'Hercules' brings something very new to the range of paniculate hydrangeas: it is a relatively compact variety, well suited to small spaces, which astonishes with its oversized inflorescences and is convincing with its very sturdy stems that proudly carry them towards the sky, without bending under their weight. It reveals itself in summer, crowned with spectacular panicles that are full of flowers that are not quite white, shaded with very pale green and pink, and the shrub remains interesting until autumn, adorned with faded flowers that are not lacking in charm. To these exceptional ornamental qualities are added excellent hardiness and great ease of cultivation in sun or partial shade and in most soils.
Hydrangea paniculata, also called Paniculate Hydrangea, is a species belonging to the Hydrangeaceae family native to the leafy forests of China and Japan. It is particularly hardy and tolerates the sun well, as well as slightly calcareous and even occasionally dry soils if they are deep.
This new 'Hercules' variety was obtained in the Netherlands after much cross-breeding and ruthless selection. This shrub shows an erect and bushy habit. The main branches are erect, while the secondary ones are slightly arched. At maturity, this variety will reach on average 1.75 m (5 ft 8 in) in all directions, with quite rapid growth. From August, numerous very dense, conical panicles, measuring up to 40 cm (15.7 in) in length, blossom on the year's shoots. They contain numerous florets tightly packed against each other. 'Hercules' has solid, well-ramified vegetation, which easily supports the weight of the flowers. Its branches bear finely dentate, ovate leaves of a fairly dark green colour, which are strongly veined and measure 5 to 15 cm (2 to 5.9 in) long and 5 to 7 cm (2 to 2.8 in) wide. They turn yellow to orange in autumn before disappearing in winter. Paniculate hydrangeas are less susceptible to late frosts, as they generally bloom on the year's shoots.
Hydrangea paniculata distinguishes itself from its cousin, Hydrangea macrophylla, by its good tolerance of sun, sea spray and relative drought. Planted in any good garden soil without too much limestone, Hydrangea paniculata 'Hercules' shows rapid growth. It is a very hardy variety, which is planted alone, in a free hedge or in a massif, or even in clear undergrowth, mixed with other hydrangeas, cotinus or even perpetual roses to play with contrasts and shapes. You can also combine it with lilies, grasses and shrubby fuchsias. Its moderate development allows it to be incorporated into a small garden and to be grown without difficulty in a large pot on the terrace where it will live for many years with some applications of fertiliser and regular watering.

Planting and care
Hydrangea paniculata Hercules is not very demanding about the nature of the soil, as long as it is not too heavy, dry or chalky. It requires a sunny but not scorching exposure, in the morning sun or partial shade. When planting, install it in deeply worked soil. A good base fertiliser (horn or dried blood) will promote the recovery of your plant and nourish it without risk of burning. If your soil tends to be dry, mix our STOCKOSORB® water retainer with the soil when filling in the planting hole and provide a watering basin on the surface.
At the end of summer, we advise you not to cut the dry panicles which will protect the terminal shoots of the branches in winter; you should cut all the dry flowers at the end of February or on the first summer days. The plant's spring vegetation appears rather late.
Hydrangea Paniculata: these shrubby hydrangeas with elongated inflorescences are a bit more resistant to drought and can easily be planted even in non-acidic soil. When planted in the sun, their inflorescences change colour in the autumn.
Hydrangea paniculata Hercules should be pruned at the end of winter to produce more inflorescences and maintain a dense habit. Apart from deliberately limiting the expansion of the bush if it has become too large, you should take care not to remove the two-year-old branches, as doing so will compromise the development of the plant.

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.
