4-Leaf Clovers # 35, 36 and 37

I often find more than one 4-Leaf Clover in one clover patch.  They are all unique.  They all have different markings, bug bites, sizes, shades of green, etc.  Some the 4th leaf is small, others they are the same size.

I asked AI why they were all different.  It said that the 4th leaf grows by accident.  It's a genetic mutation that can grow in awkward ways.  Therefore they are all different.
