The leaves are a bit wilted. A shame. They were well packaged. The delivery driver must have "confused" horizontal and vertical habit. But the young plants will recover. I'm confident. See you soon. G;G;

Description
Hydrangea paniculata Grandiflora is a stunning deciduous shrub that produces an abundance of beautiful white flower heads, which fade to an old rose, along with gorgeous dark green foliage that turns golden in autumn. This hydrangea is easy to grow and highly resilient, tolerating both full sun and partial shade and various soil conditions, provided the soil is well-drained. This large-scale hydrangea shrub will undoubtedly steal the show throughout the summer and into autumn!
The Hydrangea paniculata belongs to the Hydrangea family and is native to Korea, southeast China, Japan, and Russia (Sakhalin and Kuril Islands). It originates from deciduous forests and is a classic variety of the genus and the most commonly cultivated form since its introduction to the West. This plant grows quickly, forming a large bush with brown stems measuring 2.50 to 4 m (8 ft 2 in - 13 ft 1 in) in all directions. The plant's bushy, upright and vigorous habit is characterised by deciduous foliage that appears late in spring. The leaves are ovate and pointed, dark green, and measure 7 to 15 cm (2.8 - 5.9 in) in length. The foliage turns into a stunning golden yellow in autumn if the cold weather doesn't set in too quickly.
The Hydrangea paniculata is a highly floriferous plant with many conical, dense, and compact panicles. These panicles measure about 30 to 40 cm (11.8 - 15.7 in) in length and are made up almost entirely of sterile flowers. The flowers begin as greenish-white, then turn creamy-white, and gradually evolve into an old rose towards the end of the season. As the branches bear the weight of the flower heads, they gracefully arch, giving the bush a larger appearance. The flowers remain on the bush throughout winter, beautifully decorating the garden during the dormant season. They look particularly stunning when covered in frost.
The Hydrangea paniculata is a large plant perfect for gardens rather than pot cultivation. It is highly adaptable, easy to grow, and extremely hardy. It can survive in full sun, partial shade, and ordinary soil, even poor or rocky soil, as long as it is well-drained. There are many ways to incorporate this plant into your garden, including using it in a free hedge, as a standalone specimen, or integrating it into a bed of trees and shrubs with perennial plants. It pairs well with shrubs with remarkable evergreen foliage, dark or variegated leaves, coloured stems such as certain dogwoods, or summer or late-flowering shrubs. This contrasts with the colour of the Hydrangea paniculata, which blooms all summer long with changing hues, providing a spectacle in both summer and autumn and winter! Removing faded flowers at the end of the season is unnecessary, as they remain decorative throughout the winter and protect the stems in case of severe frost. However, if you can't resist, hydrangeas make beautiful bouquets, whether fresh or dried.

Planting and care
The Hydrangea paniculata Grandiflora is a large bush that is easy to grow and requires little maintenance. It can thrive in areas that receive full sun or partial shade. The flowers and autumn foliage will be more vibrant when the plant is grown in full sun. This plant is hardy and can endure harsh climates, tolerating temperatures as low as -15°C (5°F). It can adapt to different soil types but requires well-drained, acidic to neutral soil. You can improve the soil with a layer of leaf compost every spring, but it will still grow well in humus-rich, acidic, ordinary, poor, or rocky soils. However, it is not tolerant of heavy soils, so you should add sand or gravel to improve drainage.
When planting, whether in spring or autumn, it is crucial to prepare the soil properly and incorporate a good base fertiliser such as blood, fish and bone. Leave a space of 1m (3 ft 4 in) to 1.50m (4 ft 11 in) around the plant to allow it to grow to its full potential. While it prefers moist soil, it can tolerate temporary drought reasonably well. During the initial year, it is advisable to water it regularly and amply, especially if it is grown under direct sunlight. Watering it frequently during its flowering phase is also recommended, but be careful not to wet the leaves and flowers. During planting, which can be done in spring or autumn, work the soil well and add a good base fertiliser such as blood, fish and bone. Allow a space of 1m (3 ft 4 in) to 1.50m (4 ft 11 in) around it so it has room to spread. Although it prefers moist soil, it can tolerate temporary drought reasonably well. During the first year, it is recommended to water it regularly and deeply, especially if it is grown in full sun. Frequent watering during flowering is also advised, taking care not to wet the foliage and flowers.

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.
