For iced tea I love Celestial Seasons herbal peach tea. They also make a black tea that's peach flavored. One thing I love about them is that they are all natural, no artificial flavorings. I also like to put crushed mint into it.

For a hot tea, I love Jasmine tea. It's green tea based and a friend in LA sent me a square yellow can of it that he picked up for two or three bucks at an Asian market. He said it's just generic cheap stuff, and I haven't found it locally, yet. Very delicate.
