Hydrangea macrophylla Valvert

Hydrangea macrophylla 'Valvert' is a hydrangea with large heads that is truly original due to its colours changing throughout the weeks. This compact bush has dark green deciduous foliage, which forms a perfect backdrop to showcase the large flower balls. The green flower buds open to florets of the same shade, then streaked with pink before turning red at the end of the season. The dried flowers can then be used to create magnificent compositions for the house. It will thrive in partially shaded positions in non-chalky, moist soil and can also be grown in a container on a terrace.

Hydrangeas belong to the Hydrangeaceae family which includes 17 genera, some well-known ones like Deutzia and Philadelphus (Mock Orange), and others like Kirengeshoma that are less common... Hydrangea macrophylla is the most widespread cultivated species with numerous horticultural varieties, as this plant native to Japan inspires breeders worldwide.
'Valvert' is a recent French variety, created by Jean-Paul Davasse from the Boos Nurseries near Angers. Hydrangea is to Angers what Camellia is to Nantes, to the extent that 25% of European production is concentrated within a 30 km radius of this city. Hydrangea 'Valvert' has a dense and fairly compact growth, reaching a maximum height of 1 to 1.20 metres with a width of 0.80 to 1 metre when fully grown. This moderate growth allows it to be easily grown in a container to enhance a patio or terrace, especially since it can be pruned if necessary. The upright branches bear large ovate leaves, about ten centimetres long, with coarsely toothed edges. The surface of the leaves is dark green and slightly shiny with clearly visible veins, providing a beautiful contrast to the lighter flowers. These appear in July and bloom until September, sometimes October, making the Hydrangea one of the best flowering shrubs for summer. The green flower buds open to large inflorescences measuring about fifteen centimetres in diameter, consisting of coloured sterile florets. Initially green, they then display pink or purplish streaks in alkaline soil, while in acidic soil, the green will mix with blue. These different shades coexist as new inflorescences open, creating a constantly changing spectacle. At the end of the season, the flowers turn lighter or darker red, beautifully heralding the arrival of autumn.

'Valvert' is easy to grow in a container and can thrive in the morning sun, but should be protected from the intense midday sun. Ideally, it will be planted in a partially shaded flower bed, alongside other plants with similar needs. Although it dislikes limestone, it is not strictly a plant for acidic soil. You can create a magnificent composition by planting it at the base of an Acer conspicuum 'Red Flamingo', one of the most spectacular snake bark maples. Not only is its bark extremely ornamental but its green, cream, and red foliage contrasts with the bright red petioles and young shoots. Fuchsia magellanica 'Arauco' will also be a good companion, with its long summer flowering period that accompanies your Hydrangea, while contrasting with its radically different appearance. Its tricoloured bell-shaped, white, pink, and purple flowers, with slender petals, sway with the slightest breeze, bringing life to your arrangement. An autumn Camellia, like Camellia sasanqua 'Belinda' with its charming semi-double flowers in pink with a golden centre, will extend the flowering season.
