What is the meaning of lavender motif?

We need some context here. What are we talking about? "Lavender" is a herb with delicate light-purple flowers, and is also used for the fragrance of those flowers and their colour. "Motif" is a recurring small pattern in a larger structure. In music, it can be a phrase of four or five notes, or in literature it can be a Word or phrase or image that is repeated. I can imagine the phrase "lavender motif" applying to, say, a wallpaper design, which featured recurring lavender plants.
