There is a story among Dutch folk: In ancient times, there was a beautiful girl living in a majestic castle, and three warriors fell in love with her at the same time. One gave her a crown, one gave her a sword, and one gave her a pile of gold nuggets. But she didn't like any of them, so she had to pray to the Flower God. The Goddess of Flowers realized that love cannot be forced, so he turned the crown into flowers, the sword into green leaves, and the pile of gold into bulbs, so that when they are closed and opened, they become tulips.
