May Days
In northern France, as well as in many other parts of Europe, les Saints de Glace (Frost Saints) are reckoned and respected in mid-May. St. Mamertus, St. Pancras and St. Servatius have feast days May 12-15 and are reputed to bring a sudden cold snap. Gardeners are warned that tender plants, especially tomatoes, should not be planted out of doors until after les Saints de Glace have been on their way—in other words, only after May 15. This year has not followed convention, and cold and rainy weather in April and early May has only now given way to some real warmth and sunshine.
