What does the lily symbolize and what is the legend of this plant?

The legend says that a wicked and powerful witch once lived. It was done that everything that touched this witch pretended to be in the stone stove. If, however, he touched a child, it was transformed into a flower. At that time, there were two children, a brother and a sister who had no parents and had gone to the world to find a family.

The two children arrived at the witch's castle and, approaching the castle too much, the girl was transformed into a flower. The boy wishing to save her sister asked for help from the Flower of the Flower, which gave her a flower to help save her. It seems that this flower, if it touched a magical object of witch, broke the spell that had conquered it. With the help of this flower, the boy managed to snipe his sister and turn it back into the girl. The two of them then tried to flee, but they were caught by the witch, who transformed them into two lilies, two white flowers whose smell makes you unable to approach them. The idea was for no one to be able to approach them with the enchanted flower to save them.
