I had this for dessert last night: three flowers in a small punch teacup, continual topping up of the water. This was a bit weaker and the tea itself didn’t turn as bright green, but it was still very tasty — I think I like it a little better a bit weak, actually. The flowers started out floating on top of the tea but eventually sank to the bottom of the cup (and were very pretty to look at as I sipped). Interestingly, given the lesser coloration of the tea, when I washed out the cup this morning the flower petals had streaks of green staining them!
Reading up on chrysanthemum teas, I hear that they aren’t generally soporifics; apparently it’s just coincidence that I conked right out after finishing my last cup of this last night! I guess it was just plain old soothing.
