"In modern Polynesian culture, the flower can be worn by women to indicate their relationship status—over the right ear if seeking a relationship, and over the left if taken."

Oh, and the term, sphinx moths, include the hawk moths whose larvae I featured last month. Everything fits together, and I wonder how many buds will open in the next few days.
