That's an interesting idea too. A long shot this one though..<gg> but, courtesy of Andrew's excellent Index to the BSS Bulletin, I have been able to find again (see BSS Bulletin Oct 91(3) p4) mention of a Nineteenth Century pastime of constructing (visual) sundials made up from thirteen flower varieties that (allegedly!) open at different times of the day from 6am to 6pm.. I remember when I first saw this article being amazed that such an effect allowed time to be assessed to about an hour - and sometimes apparently even without direct sunlight too. Perhaps then there might be a range of flowers whose strength of scent might vary by time too... Hmmm, I'm probably clutching at straws here - either that or the plants that do have such an effect will all turn out to be from the wild garlic family!! Patrick -
