Perianth Segments

A typical (not double) daylily flower has six perianth segments arranged in two rows. The three inner ones are the petals, and the three outer ones are the sepals. The term “tepal” may be used to refer to any of the six, because they are relatively undifferentiated from each other as compared to many other plants, such as roses. Also see: Petal, Sepal, Polymerous.
