Type your town or postcode in France below: you get the estimated winter cold where you live for each level of caution and, at the bottom of the page, the available plants that withstand it. Choose your caution towards frost. “Conservative”: the worst winter of the last 30 years. “Cautious”, the starting setting: the cold that comes back about one winter in ten. “Normal”: the cold reached about one winter in five. “Gambler”: the average of 30 winters, like the USDA hardiness zones; about one winter in three goes lower. “Daredevil”: the average of the last 5 winters, a bet that winters stay as mild as in recent years. It is not the average that kills a plant but the hardest frost. The more you gamble, the wider the choice of plants, and the greater the risk of damage.
