I think we should take care to distinguish individual flowers that remain in bloom a very long time (like my Narcissus romieuxii which last at least 6 weeks in the garden) from plants that have short-lived flowers but continue to open new flowers over a long period. Someone could even do some research on the causes. Is it my cloudy skies and lack of pollinators? Are the flowers patiently awaiting pollination?
