Flower arrangement

Pink flower   Statice
Yellow flower Cornus officinalis
Purple flower Iris
As for the iris, the iris is considered to be “the friend of the iris” in a bundle with plants of the Iridaceae including a sweet flag and the rabbit-ear iris. It is Cornus officinalis to be hard to understand. Originally just assumed “山茱萸” of Chinese a name, and another name called harukoganebana is so, do not think that this is more plain?
