Wim,
You asked me when you will be able to detect the difference between the
normal (anthocyanin-containing) and variant (anthocyanin-free)
Darlingtonia. I have a lot of experience with Sarracenia, and think I
would be able to detect the difference in seedling plants (a year or so
old). Look for lime-green coloration in the variant plants, while the
growing points of the normal plants (apical meristem area) will be blushed
with red or pink.

If and when this plant is formally described in a botanical journal, it
can be given a name like Darlingtonia californica f. luteola or something
like that. Because an anthocyanin-free variant of Sarracenia purpurea
subsp. purpurea has been botanically described as f. heterophylla, some CP
enthusiasts add "f. heterophylla" onto any anthocyanin-free variant. This
is incorrect.
Cheers
Barry
