Dwarf Cinquefoil

Cinquefoil is french for five leaved. This flower appears to have five leaves but I have read that it is one leaf deeply divided. It does have five petals. It makes its home in the poorest soils and if the soil is improved upon it does not return. I also read that the leaves look like a priest's hand held up as if to say " stop " .... and so it was used to keep away evil spirits.

Where I found it : In an old field
