Name of the hydrangeas

The question of the name

The confusion about the name of the species or varieties of Hydrangea begins very far in time. Certainly the hydrangeas grown in the natural state or grown in Japanese gardens, some of which in turn came from China, already had proper names long before Western botanists became interested in them. Probably, however, the barriers represented by the diversity of language, contextual to the urgency of naturalists "hunters of plants" to identify and classify imported varieties, prevented the transfer of names or their understanding. So new names were assigned and botanical descriptions were soon made, but almost never in unison. Thus over time a rather uncertain situation was created which, although to a much lesser extent, still persists today due to the lack of an official and universally accepted classification. To this we must add the current tendency of some producers to rename, at their discretion, cultivars that actually have their own names, thus feeding the existing confusion. This is why a rigorous botanical classification is not possible: it is possible to carry out a series of groupings or taking into account the main species, or on the basis of homogeneous characteristics (this is the case for example of H. petiolaris, H. anomala cordata, and H. seemanii that can be grouped together in the "climbing" group, although the latter is not a true botanical species) in order to make it easier to identify and identify the individual varieties or cultivars available.


The common name given to these plants, takes its origin from a name coined, in the mid-eighteenth century, by Philibert Commerson, a French naturalist who brought this particular flower to China from China.
Naturally the genus is formed by different species both shrub and climbing, which have some common characteristics and others specific to the variety to which they belong.
All are characterized by the particular inflorescences that make these plants particularly recognizable.

Hydrangea macrophylla

Speaking of the name hydrangeas, one of the main varieties, as well as one of the most known, is certainly the hydrangea macrophylla, which is also well suited to cultivation as a houseplant.
There are numerous varieties, characterized by flowers with spring or summer growth with different colors. It is semi-aristocratic in nature and has large, serrated, deciduous leaves. The flowers of these hydrangeas can take on different colors also in relation to the substances found in the soil where they are planted. Some types of hydrangea retain their color despite the environment, such as white hydrangeas, while the pink color is given by soils with little aluminum, alkaline and calcareous, while the blue color derives from acid and aluminum-rich soils.

Hydrangea name: Hydrangea paniculata

Another name of a rather known variety is hidrangea paniculata, a shrubby species, which presents good rusticity and a pink or white summer bloom.
Its flowers are details that develop in the shape of a panicle while the foliage has leaves with sharp edges.
It is a variety that can reach up to 6 meters in height and that does not present particular difficulties for cultivation, thanks to its excellent resistance.
Other varieties of hydrangea that can be successfully grown are the one with the name hydrangea arborescens and the quercifolia, which is a species that usually does not exceed one meter in height.
