Rick, Your absolutely correct, it seems to defy any biological sense whatsoever, but have you ever experimented a little to detect the difference? I never would have thought that either, but one day a few years ago, an elderly (very) lady was here sniffing my flowers when out of nowhere she blurted out: did you know---. She then proceeded to show me, and by golly, it's true. The fragrance is more concentrated at the tips and along the outer edges of the petals. Try it sometime, Rick; you'll see for yourself. I've since observed that this is hardly evident the first day of opening, but increases dramatically the second and third day, etc. Since then, I have reversed the way I smell lilies. I now hold the flower so the reverse is facing me and I smell only the edges and tips from the reverse.
