Fresh green, bright white, sky blue, deep purple, lilac and pink. Flowers that can have a diameter of up to 25 cm, that are shaped like fluffy clouds – the Hydrangea is the ultimate symbol of high summer, the period of hot days, long evenings and sultry nights. When everyone takes it a bit easier. Hydrangea’s soft round shapes fit with this and can easily be included in arrangements to provide a soft landing. 






The Hydrangea is a member of its own hydrangea family. The ancestral species Hydrangea macrophylla, from which most cultivars are derived, grows along the coast south of Tokyo in large numbers. The flower, which originates from Asia, arrived in Europe with the first Dutch East Indies Company ships and became popular in around 1735, surprisingly both in castle gardens and alongside farms.

The most common Hydrangea is Hydrangea macrophylla with its globe-shaped blooms. There are both single-flowered and double-flowered varieties, from small ones with a diameter of 8-10 cm to very large with a diameter of 25-30 cm. H. macrophylla is available in dozens of cultivars in white, pink and green through to blood red and bicoloured. The grower can turn the flowers blue by adding special substances to the water.

In addition to single coloured flowers, there are also bicoloured varieties. A total of some 150 different cultivars are available in August. The colour-changing hydrangeas are also available in that month for real enthusiasts. In addition to the cut flower with the round flower clusters, growers also offer Hydrangea paniculata with white and green plume-shaped flowers.


What to look for when buying hydrangeas?

  • Different cultivation conditions (light, nutrients, age of the crop) can produce very different results with the same cultivar. Ask for a real-time photograph of the product, particularly when purchasing online.
  • Check the height, ripeness, flower diameter and whether it is a fresh or colour-changed hydrangea. The stem must be firm, straight and not twisted.
  • The flower must be free of pests and diseases. Hydrangeas can sometimes show botrytis (grey mould) on the flowers or the foliage.

4 Care tips for professionals

  1. Place the flowers in sufficient fresh cold water, and always use cut flower food. Cut flower food will extend the lifespan of hydrangeas by over a week. That gives a vase life of 3 to 4 weeks.
  2. Hydrangeas can be used in a vase and in oasis, but cannot cope with being dry. You should therefore ensure sufficient water (2/3 in the bucket or vase) and pre-soak oasis thoroughly. Trim the stem diagonally to ensure good uptake of water.
  3. If the flowers are drooping when received, cut 3-5 cm off the stem and leave them in a cool space wrapped in paper for around three hours to take up water and recover.
  4. Preferably avoid using metal or zinc vases for hydrangeas; a glass vase is better. Remove surplus leaves and immature or unnecessary side shoots. Foliage that hangs in the water causes unnecessary contamination.



Style hydrangeas on trend in cool clear glass for a peaceful look, surrounded by colours such as lilac, pink and yellow. Adding some exotic companions makes it an extravagant high summer, but remember to leave space in the arrangements, as if a refreshing breeze could blow through them.
