Vespertine is the name of the latest perfume created by Sebastian Fenix. It’s a fictional perfume, but there’s more to it. The yellow flower on the label is reminiscent of the datura flower in bloom. Not coincidentally, datura is a vespertine flower, meaning that it blooms in the evening. Furthermore, it’s a poisonous flowering plant, a nod to the shady perfumer who created the aforementioned fragrance.
