It has become naturalized on some areas of Staten Island. It is a parent of the Shasta Daisy, Leucanthemum x superbum.Like its offspring, N. nipponicum exhibits much conical cell shimmer in UV.

nfoto Posted December 14, 2013 Share Posted December 14, 2013 Apparently this particular flower head has seen rain recently. Agree that shooting the UV-Nikkor wide open isn't the best way to get good bokeh in UV. Its scientific name more than suggests a Japanese heritage :D Link to comment
Andrea B. Posted December 14, 2013 Author Share Posted December 14, 2013 Well, interestingly, that is not water on the rays - at least at the time of the photograph. But something has eroded portions of the ray surfaces. Link to comment
nfoto Posted December 14, 2013 Share Posted December 14, 2013 I've have seen similar spotting on flowers and corollas that have experienced rain in the last 1-2 weeks, then dried. So I was not thinking about water per se. Link to comment
Andrea B. Posted December 14, 2013 Author Share Posted December 14, 2013 OK, that is likely what has caused the mottled appearance then. But why would rain cause this mottling sometimes and not other times ? This plant grows near the street, so perhaps some kind of spash of rain combined with street debris from passing tires was harsher on the plant than just plain rain ? Link to comment
