RE: Into The Night

This is a flower I have always liked. I did a pigment extraction analysis of 
this flowr this year as I had some suspicions which were confirmed  by the 
analysis. The falls had yellow pigment in them while the standards didn't. I 
also did a quantitative comparison of anthocyanin pigment in falls and 
standards. I did this by cutting equal sized pieces of standards and falls. 
The amount of anthocyanin pigment was almost idemtical, allthough there was a 
very slightly more pigment in falls, but a very small difference. Basically 
the falls were darker because the anthocyanin was combined with a yellow 
amoena.  I persomally suspect the colour of standards is about as dark as we 
can get in iris without a carotene underlay.

Now think of such flowers as 'Local Color'and 'Romantic Evening'
