Ancient Druids felt trees were sacred, and mistletoe was magical.

During their winter festivals, they cut mistletoe from branches of an oak or apple tree with a curved golden knife and caught it in white cloths before it could touch the ground.  They believed that the green leaves and waxy white berries brought love and good luck into their homes.

They believed that because of its magical powers, anyone standing under mistletoe must be kissed or the mistletoe would lose it's powers, and the person would be unlucky in love during the coming year.
