Are There Hydrangeas That Are Naturally Blue?

A friend told me that no hydrangea is naturally blue. One has to be forced through one method or another to create that color. I find that hard to believe. My grandmother always said that one had to plant iron nails in the soil to create the color one wanted. I don't remember doing anything special to mine but it is a beautiful blue and has been for many years. Anyone know anything about this please? Thanks.
