Lichen

Lichen

The lichen, lichen in Latin and leikhên in Greek, is from the Cladoniaceae family, which has more than 20,000 species, most of which are still little known. Lichen comes from a green alga and a mushroom. It develops in all countries of the world, without any human help, in all climates or almost since it does not develop in glaciers, nor in eternal snow, nor at the poles. It colonizes trees, stones, walls, rocks, and even inside dwellings or churches.

Particularity of the lichen

The lichen has no root. It is by all its faces that it absorbs water but is able to do without it during periods of drought. It then enters a semi-rest phase until the rains reappear. It is also possible to find lichen in the middle of the desert. Often considered a problem, the lichen is an excellent indicator of pollution. Where the atmosphere is healthy, it develops. You should know that we get antibiotics, dyes, but also perfumes from the lichen.

Lichen size

When the lichen is invasive in the garden, it is necessary to brush each covered tree trunk. Indeed, the lichen cannot be pruned but resists lime milk poorly.

Lichen diseases

The lichen is not afraid of any disease.

Lichen plantation

Often considered a moss, the lichen is an epiphyte. This means that it can grow on other plants. In the garden, the lichen has no need of the human hand to develop.

Lichen watering

The lichen does not need to be watered.

Lichen maintenance

The lichen does not require maintenance.

Cosmetics and lichen

In perfumery, we use Evernia prunastri (oak moss) and Pseudevernia furfuracea (tree moss). These lichens provide the basic touch of certain so-called woody fragrances. To do this, almost 10,000 tonnes of lichens are used annually to extract the fragrant essential oil.
