I love LOVE making sun tea! I've got probably four half-gallons in the fridge right now, all different flavors. One I experimented with yesterday was yerba mate, a cinnamon stick, and stevia--but it looked nowhere as beautiful as yours did while brewing. :) Can't wait to get some going with actual plants from our land.
Of course, it did take me some time to carefully arrange the flowers so all the pretty colors would show for the photo! haha
