I had no idea what the dandelion leaves meant, so you forced a google upon me.
"There is an engaging legend about the origin of the dandelion. Centuries ago, a miser found a pot of gold. He decided to bury it where no one else would find it. He took the gold home, placed it in a sack and went to bed. During the night a mouse gnawed a hole in the sack. The next morning the miser took the sack into the woods to bury it. He was unaware of the hole in the sack and the gold dropped out, coin by coin. When the miser realized this he retraced his steps, intending to pick up the gold coins. However, he found that the coins had been turned into beautiful yellow flowers and were rooted to the ground. The wood sprites had overheard his plan to bury the gold and to punish him for his selfishness they had turned the gold into dandelions for everyone to enjoy and share."
Is this why ?
