Comment:

The actual yellow discoid flower of Pearly Everlasting is contained inside the white papery phyllaries. The plant is native to Asia and to North America. Varieties of A. margaritacea are grown ornamentally and for use in dried flower decorations.

In UV the white bracts are UV-dark with brighter tips.

Visible Light [f/8 for 1/2000" @ ISO 400 with Nikon Df + Nikon 60mm f/2.8G Micro-Nikkor]

 

Visible Light [f/8 for 1/3200" @ ISO 400 with Nikon Df + Nikon 60mm f/2.8G Micro-Nikkor]

One captiulum is open enough to see the tops of the unopened yellowish disk florets.

 

Equipment [Nikon D600-broadband + Carl Zeiss 60mm f/4.0 UV-Planar]

Ultraviolet Light [f/11 for 15" @ ISO 400 with SB-14 UV-modified Flash and Baader UV-Pass Filter]

A long exposure was taken so that the flash could be fired 3 times for a more even distribution of UV light.

Some cypselae lie on one of the capitula.
