During the Middle Ages, green became more than just a symbol of positivity. It was associated with luck and love. Marriageable young women wore green. It was also the color of choice for pregnant women—a nod to the hopeful fertility of spring.
No wonder, then, that medieval youth frequently wore green. On the equinox (March 21), they would take it one step further with young men covering themselves entirely in plant life to appear as the “leafy man” or “moss man,” and would then run around creating chaos to proclaim the end of winter.
