Switzerland constitutes the northern limit of the cultivation zone, where the climatic conditions are favourable to the growth of the olive, a plant sensitive to cold. The Flora Helvetica, the reference work for identifying flowering plants in Switzerland, describes the olive habitat: "Rocky slopes, bushes, cultivated and rarely wild in southern Ticino". The highest olive grove is found in Mairengo (Faido), at 907 metres above sea level.
