May 1, labor day and "lily of the valley" day

I really like the tradition of offering these pretty little white flowers to friends, family and loved ones. 
"As the story goes, on the first of May 1561, King Charles of France—who was ten at the time—was presented with a fragrant bunch of muguet: the delicate green sprigs capped with tiny white bells that we know as lily of the valley. It was a gesture signifying luck and prosperity, which so touched the king, he continued the tradition by giving the sweet-smelling blossoms to the ladies of his court each year on the same day". http://www.vogue.com/vogue-daily/article/lily-of-the-valley/#1
