The mild climate that is a characteristic of the Lake Como region has since ancient times encouraged the growing of many plant species along its shores. Many of these have come from other parts of Italy and the world and include olives, oranges, lemon trees, shrubs and rare tropical flowers. These have all found the ideal soil and weather conditions for their development and now adorning the gardens of the historical villas that stand all across the region.
The natural parks, such as those of the Lambro or Adda Valley feature forests of oak, chestnut, hornbeam, elm, poplar and broad-leaved trees.
When climbing the slopes of the mountains, you will mainly find coniferous forests, which open out near their peaks to the high pastures.
