Blue: Mystery and uniqueness
Blue is not so common when speaking about roses, because unlike most colores, blue does not exist in nature. However, blue represents mistery, the impossible and the unattainable.
Choose blue roses when you want to tell someone indirectly that they are one of a kind, they’re special and different from all you have seen. If they do not know what blue roses symbolized, make sure to tell them, this way they’ll appreciate your gesture even more.
