UV-Sonnar 105mm, Hasselblad 501 C/M body, Phase One digiback

[that "black" background cardboard I was using was not black in UV]

Not much to see in UV except the lit tips on the petals and the structure
on that petal surface which gets visible.

DR,

as the flowers become more mature does the amount UV increase? (on your blog you said they had just started to flower)

Not those, but others with more prominent UV patterns do (Creeping Zinna - Sanvitalia procumbens) is a good example for that.
Their UV pattern mature and later disappear when the flower reaches its end.

DR,

I have looked at this on another site - do you have a life span set of images?

cheers

Nope, only some pictures taken in different years of different stages of that flower.
