Eucalyptus Feuilles de L'Herbier de France comes from a tree capable of withstanding extreme conditions. It has rare biological features for this: its vertically oriented leaves have the same capacity to produce chlorophyll below and above the leaves. It also has “lignotubes” which are a pseudo-root, under the ground near the tree collar, allowing it to be reborn after a fire of its aerial parts. Finally its seeds are enclosed in very resistant capsules ...

The result is quite successful, but the eucalyptus dominate the flora, and biodiversity declines in the areas where it is established. In addition, the eucalyptus forests are very flammable and we see gigantic fires appear in monoculture areas. These areas are also expanding, since eucalyptus also provides a cheap raw material for papermaking ...
