I am looking for papers on bluing of red roses. I found one on this affect on red “ground”roses but lost the reference (help).

I have notes on a number of papers that may be relevant.

Some substances in a rose become more concentrated as the flower ages. Others fade. A red rose can "blue" with age as the quantity of co-pigment increases.

These folks attribute age related bluing in roses to be due to the cellular pH increasing with time and to quercitin complex formation over time.

What doesn't kill them makes them stronger.
