    Mexican Zinnia flowers have a very specific UV pattern. Their petals are very UV dark on
    the middle and bottom, but their petal tips are very UV bright, reaching much deeper
    into UV as any other flower I know (< 345nm)

    All diptych images show left results using UV/Cut filter for the visible shots and right using
    the Baader-U filter (approx. 320-395nm, peak approx. 350nm) for the reflected UV shots.

    That's fascinating. I may use these (with your permission) in my fall term chemistry course. You never know what particular example will stick with a student so I try to show a variety of phenomena for each concept.
