[VIS, UV] Helianthus: new vs old flower made visible using ultraviolet light

While I was shooting flowers at Herrmanshof, Weinheim park, I noticed that in UV the ageing of a flower can be easily detected, wheras in visible light, they look alike.

Standardized reflected false UV "colors" according to the previously described "UV color palette" related to wavelength:



These yellow Helianthus tuberosus flowers on teh left side, clearly show age differences: top is in male stage (early), bottom is in female stage (late) but in UV things get much clearer! So I'm sure our beesies knew that way before us...

Stay tuned, more will follow on that fascinating subject...
