What flower is the goddess Popula?

It's not a poplar flower, it's a flower god, it's a character in Little Flower Fairy, and the flower god who once spent the fairy world has passed away. With the death of Popula, the goddess of flowers was automatically passed on to Tiwenti. The constellation is Capricorn, the guardian spirit is the guardian spirit of the twelve styles (national gardens), and my sister is Yaga.
