In Olivane (900 m), the four sage varieties (Salvia officinalis L.) Regula, 13/6, Valy and Montenegro were tested for their frost hardiness, their agronomics aptitudes and the chemical composition of their essential oils. Valy and Montenegro were very sensitive to frost despite the installed protection against cold. 13/6 was the most tolerant variety, followed by Regula. The latter was the most productive, showing a fine and regular vegetative growth. Overall, 13/6 showed the most regular vegetative growth and Montenegro was characterised by its weak growth. For all four varieties tested, the content of essential oils and the amount of principal molecules thujone and camphor was modest. Compared to the other varieties, Montenegro had the lowest content of campher and borneol.
