France La Poste released a series of stamps with the languages of flowers.
Although today nobody offers flowers according to their language (except for some most symbolic ones such as Rose, chrysanthemum, Lily of the Valley, etc.), and I am the first to buy flowers just for their natural beauty, I also believe that a flower and the gesture of offering a flower would become more meaningful if we try to compose a message with them.
Arum Lily: Ardour
Lily of the Valley: Happiness
