The garden of the museum is not born by chance. It wants to give a suggestion. The walk that crosses recalls the path of a river and, on its "banks", there are some plants that existed already in Pleistocene. Almost all are still part of Mediterranean and temperate environments that characterize the Italian peninsula.
There are shrubs that can become small trees, fragrant and aromatic plants, which perhaps were known to our ancestors for their qualities and properties.
And then there are true trees that, especially in "hot" and humid periods, expanded beyond the river valleys.
A single plant is no longer widespread today in Italy, while it widely populated the Pleistocene environments: the Zelkova. It can be seen "fossil" in a showcase in the museum and "alive" in the garden.
The following text also is a suggestion. The plant world is a living world, and therefore it is likely that some plants are today different from those described here.
