Due to its hardiness, my choice for this spring is to plant in large wooden containers on my terrace.

Description
The 'So Long Rosy' is a new hybrid hydrangea series that combines the best qualities of its parent plants. This plant can resist cold weather and bloom on the current year's wood. It has beautiful inflorescences that shift from soft pink to chartreuse green. It blooms early and continually throughout the summer despite rain with well-coloured flowers. Its semi-spherical flower heads gradually evolve from pale pink to chartreuse green. The plant is not too big, compact, and well-branched, making it easy to fit in a small garden or container on the terrace. It grows best in semi-shade.
Hydrangea serrata are plants that thrive in cool and humid mountainous regions and are resistant to cold temperatures as low as -20°C (-4°F). They are less affected by late frosts compared to their large-leaved counterparts, all of which belong to the Hydrangeaceae family. The 'So Long Rosy' hortensia is a very bushy plant that can grow up to 1.10 m (3 ft 7 in) in height and 80 cm (31.5 in) in width, depending on the cultivation conditions. It starts to flower at a young age, and its hemispherical panicles, about 13 cm (5.1 in) wide, bloom from June. If the plant is pruned slightly after the first flowering, it will form new flowers during summer. This hydrangea has large, medium-green, ovate leaves with a dentate border, which fall in autumn. It's worth noting that hydrangeas are sturdy plants that can survive for at least 50 years.
Hydrangea So Long Rosy is the perfect plant for adding a romantic touch to your garden. This plant thrives in fresh soils and semi-shaded areas, making it perfect for placing near the house, on the terrace, or near the entrance. You can also place it on the east or west side, as long as it is not in direct sunlight. Even if they are not fond of limestone, hydrangeas are not strictly ericaceous plants, they like humus-rich, fertile and fresh soils. Pair them with other plants such as fuchsias magellanica, annual impatiens, lilies, Pieris, Sarcococca, or plant spring-flowering bulbs in front of their round shape. You can admire their beautiful and long-lasting flowers in your garden or even indoors. Their dried flowers look great in bouquets, so don't be too quick to put them on the compost heap after they have bloomed.

Planting and care
To plant the So Long Rosy hydrangea, choose a slightly shaded spot in spring or early autumn, such as against an east-facing or northern wall. Keep it away from cold winds and the sun. It prefers deep, fresh, well-drained, and relatively fertile soil, but ericaceous soil is unnecessary. You can enrich the soil with a good base fertiliser before planting. If the soil is dry at the foot of the wall, plant the root ball at least 30-40 cm (11.8-15.7 in) away from the base and add well-rotted compost to improve soil freshness. This plant is resilient and can be planted in cold areas. When pruning, remove the faded flowers on the first or second bud. To encourage the formation of young shoots, cut back a quarter or a third of the oldest stems to the base when the plant matures. Prune every year in March or 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).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
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 planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
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.
