Ivy also has such a legend:
A long time ago, ivy was considered a magical plant and a symbol of loyalty. Giving ivy to a friend means everlasting friendship, while giving it to a lover represents everlasting love. This is why ivy often appears in Western weddings. Wearing a headdress made of ivy on the bride's head can be used to ward off evil spirits and keep love fresh. If a boy wears ivy, he can tell whether his lover is sincere or not.
