I've always wondered how fragrance is carried in the air. How does it travel? Does it attach to something? Or is some sort of molecule thrown off that flies on its own? I didn't notice any odors coming off my daylilies this year that I recognized, but sometimes the source of odors can be elusive. Has anyone noticed whether weather conditions such as high or low humidity affect the strength of a fragrance? Not quite on topic, I guess.
