What are some good types or flavors of tea (real tea) to make iced tea from, for a party?

I am having a party for my mom’s birthday, which is toward the end of June. It’s just a casual thing out on the deck, and since it will be summer time I want to serve some iced tea. I know there are tons of varieties and flavors of tea out there. What are some types or flavors of tea that I can make some nice, unusual iced tea out of?
