Chrysanthemum tea does not actually contain any tea leaves. Instead it is a flower-based tisane made from chrysanthemum flowers of the species Chrysanthemum morifolium or Chrysanthemum indicum, which are most popular in East Asia. To prepare the tea, chrysanthemum flowers (usually dried) are steeped in hot water (usually 90 to 95 °C (194 to 203 °F) after cooling from a boil) in either a teapot, cup, or glass. However, Chrysanthemum flowers are often paired with Pu-erh tea, and this is often referred to as guk pou.
