Comment: Sweet William Pink is a garden import from Europe (and/or Asia) which escaped to naturalize widely across the country. The fancier forms are still popularly used in the garden. This naturalized specimen has UV-dark petals with a central UV-bright ring and UV-bright petal edges. There appear to also be some shiny iridescent streaks probably caused by conical cells.

Andrea, have you done a hydrangea? This reminds me quite a lot of the UV response I saw from those, in particular the iridescent streaks on the dark petals.

I see that shiny streaking a lot on poppies. See last UV photo here: http://www.ultravioletphotography.com/content/index.php/topic/672-eschscholzia-californica-subsp-mexicana-mexican-gold-poppy/

The particular hydrangea I've photographed did not show it so much. But there are many different types of hydrangea. "-)
