To refresh my memory (or more honestly, to put something <in> my
memory), I'm going back thru the archives reading up on delphinidin -
it's spelled differently by different posters, so thought I'd share this
tip - search for <delphin> with whole word match turned off.

Chuck, there's a post from you back in 2005 that says, in part,
<The anthocyanin colour in pallida is a lighter tone,
more lavender then the anthocyanin seen in other iris species. It is
still a
form of delphinium but has different sugar and hydroxyl attachments etc.>

Do you know if more is known now about how the various forms of
delphinium/idin/in? Can only one form of anthocyanin be present at a
time? Is there a sequence of dominance?
