Herbs in your coffee?

I love brewing coffee in a French Press. Recently I thought I'd experiment with putting some lavender in the coffee grounds, and I liked it! I have to figure out the best ratio though, and I'm sure the type of coffee makes a difference. I usually like an espresso roast.

I was wondering if anyone else puts herbs in their coffee? If so which ones? And what type of coffee?

Or in absence of herbs, how do you like to dress up your coffee (if at all)? I'm looking to dress up my morning beverage routine.
