Celebrating this year's favorite colors: Blushing Pink and Light Green . Cute little Butterflies are flying over fields of Spring Flowers ( Lilies of the valley, Sweet violets, Pansies and Daisies) : a classic Spring Design. In the Victorian language of flowers, lily of the valley meant "return of happiness", a delicate symbol of purity and sweetness. Renowned of its fragrance and delicate nodding white flowers, lilies of the Valley have a very special place in France. On the 1st of May, for la "Fete du Travail" (Labor Day), it is a French tradition for friends and family to offer each other little bouquets of lily of the valley ("muguets") for good luck. The more little bell-like flowers the plant has, the better the luck.
