The four-leaf clover

The four-leaf clover occurs as a result of a rare leaf growth mutation in white clover, the most common species found in grasslands. This mutation is determined by a gene activated by environmental pressure. If you are lucky enough to find one, it is likely to be surrounded by other four-leaf clovers. White clover grows in soil that tends to be chalky, full of water and organic matter. It is abundant in pastures constantly trodden by animals. A synonym for luck and patience, it's a beautiful memento from our childhood.
