Lake Como has always been renowned for its climate, generally mild and humid, which encourages a rich vegetation. In the sunniest areas  in winter the weather never reaches very low temperatures. In summer the heat is not oppressive as it is mitigated by proper ventilation.

The flora, diverse and luxuriant, is Mediterranean, on the shores of the lake grow cypresses, laurel trees, camellias, azaleas, rhododendrons, magnolias and palms. In some areas more sheltered and humid also grows tropical and subtropical vegetation. In Villa Cipressi and Villa Monastero gardens, famous everywhere for their splendid parks full of flowers and rare plants, here in the hot season flowering azaleas, cacti, ferns Southern, palms, conifers, cedars and orange trees.

Cultivation of vines and olive trees are not very abundant also due to the geological nature of the soil and is found only in some areas. On the slopes of the mountains around the lake abound forests of chestnut trees and in higher areas, pastures where spring flowering daffodils and lilies.
