In autumn, the leaves gradually lose the color they have maintained throughout the year and take on a warmer hue, while the days grow shorter and the air temperature steadily drops. It is precisely the cold and the reduction in daylight hours that trigger the process in deciduous plants (those that shed their leaves) leading to the gradual change in leaf color.

In the Biella area, there are many places where you can admire the "foliage." Among them are the Oropa Botanical Garden and Sanctuary, as well as the Zegna Oasis.
