Re: Re:TB, lumis, plics, Silverado

Hello Neil,
Do you know any study of Iris aphylla pigments?
Seeing I.aphylla in wild I noticed its color varies normally from dark to
light and from more red in violet to less red in violet, but red tint is
present always. I had a chance to find a form that look like an albino but
was not white but sky-blue, PBF common in aphylla desappeared in this form
too. My impression was there is two different antocianin pigments: one is
blue and another is red-purple, and these pigments are due to different
genes.
