Four leaf clovers tend to prefer slightly shady, cool, and wet areas. Ideal temperature for growing appears to be between 55 and 70 degrees Fahrenheit. Individual plants will have all four part leaves, so if you find one, you should be able to find others and/or be able to wait until the plant regenerates itself to find another.

I've noticed that finding four leaf clovers is just a matter of having the right search image. Four leaf clovers often stand out, and may even be the tallest clover around. I've often found five, six, and sometimes even seven leaf clovers in the same area as the four leaf clovers.
