What a thorough and interesting post. Even though I usually get lost at scientific jargon, I kept reading this one. It was worth it.
Really fascinating facts about a rather insignificant plant (at least in my culture).
We do get the lucky reference from the media, cartoons, legends, etc. But very few people would contemplate or search a clover field here hunting for a 4-leaf clover.
Nature is amazing and complex and we have to tip our hats to those who venture in its study and understanding.
