By the name "Hydrangea" we mean all those plants belonging to the Hydrangea genus, climbing or shrub type, originating in the eastern regions of Asia or South America, and introduced into Europe between the XVIII and the XX century. The stems are robust and woody, with toothed or lobed leaves. The flowers are actually colored sepals, which surround real flowers, which are tiny. These inflorescences are gathered in spherical form (corymbs) or in the shape of a panicle in the "paniculate" varieties and bloom between spring and summer. The color of the sepals can vary between white, blue and pink in all its shades. Then there are varieties that only recently we can find in our nurseries and that have inflorescences with small and curved petals, or with only the colored margin.

Hydrangea is a shrub that is also suitable for growing in pots. Both at home and in the apartment, the plants must be planted in large pots, guaranteeing them regular watering and fertilizers rich in nutrients to ensure abundant and luxuriant flowering. They prefer a sunny position, but not direct sunlight, which would cause the stem to bend. Even the temperatures must not be too high. Hydrangeas are in fact robust plants, capable of withstanding even frosts, but they fear the heat. The ideal growth temperature is in fact around 18 degrees. If grown indoors, simply place the pot near a window (to ensure the light needed for the plant) but away from heat sources.
