Kelbaker Road, Mohave National Preserve, San Bernadino County, California, USA

20 February 2016

Wildflower

 

Synonyms:

  • California Chicory
  • New Mexico Plumeseed

Comment:

Interestingly, the Desert Chicory has a UV-dark bullseye even though its rays are also UV-absorbent. The UV-bright, pollen laden anthers stand out brightly against this dark background.

Lots of practice, heaps of patience and a few spoonfuls of plain old luck !!

 

But really it isn't "always" that I get nice photos. You just don't see the really bad ones. :lol:

 

As an example, I didn't do so well with the little Desert Gold Poppy recently posted. If I get a chance to photograph it again, maybe I'll get a better one to replace this.

I got essentially the identical UV signature for R. neomexicana on the 2012 Desert trip with Andrea. She, however, as usual makes the better images.
