Lily of the valley ('muguet' in French) is closely related to May Day (or Labour Day) in France. Traditionally, lily of the valley is sold everywhere on streets across France on the first of May and is one of the symbols of springtime and a good luck. Lily of the valley is a delicate fragrant flower, which according the tradition has came into being from Eve’s tears when she was forced to leave the Garden of Eden. Another tradition confers the existence of the flower to the Virgin Mary as a result of her tears at the Crucifixion. The tradition of offering lilies of the valley dates back to May 1st, 1561, when King Charles IX of France received the flower as a lucky charm and for prosperity.
People give lilies of the valley as a token of appreciation between each other, with wishes of happiness all year long.
