Oak leaves

The genus Quercus

There are many varieties of different trees in nature, each one distinguished by color and size, by the use made of it, by the places in which it grows. A genus that has always played a large part in Western mythology, especially in Celtic mythology, is the oak. When it comes to oak, everyone immediately thinks of the type of tree referred to, but in reality the genus, which is called Quercus in botanical terms, includes about 450 different species, existing in nature. The family to which they all belong is that of the Fagaceae, which is also widespread in Italy, where it is not difficult to find oaks. In the past these plants were of considerable importance for the breeding of pigs, which fed on its fruit, the acorn. Today they are appreciated for their wood, and for ornamental purposes.

The various species of oak


Although all oaks have common characteristics, they differ in several details, not least the oak leaves. The leaves in fact can differ in shape, color and size. The most common qualities of oak, even in our country, are: – Quercus Robur, more common in the north. It often meets in oak woods with other plants of the same genus, and its name identifies one of its main characteristics, namely robustness and longevity; – Quercus Pubenscens, also called downy oak, is widespread in the flat areas and has an average life span of 2 or 300 years; – Quercus ilex, or holm oak, is found widespread in the Mediterranean areas; – Quercus Petraea, or oak, is widely used for its precious wood in order to make furniture, and is found throughout the Italian peninsula.


A strongly characterizing element of the various oak species are their leaves: observing the oak leavesit is very easy to distinguish which specific tree type you are in front of. A first major distinction that can be made is between the so-called red and white oaks. White oaks have rounded leaves, red ones pointed. Another big distinction can be made between deciduous and other evergreen oak leaves. The first ones change color in autumn, taking on yellow and red tones, and finally falling off. The others, on the other hand, always remain their color, a beautiful bright green, even in winter. To identify a tree more specifically, one can consider the specific shade of green of the oak leaves, whether they are shiny or not, and the number of side lobes that they show off.
