I'd be wary of any labels like "red tongue," since from any one batch you might end up with numerous color forms. I'm thinking the Siskiyou seeds I have may just be old (and now you've got me thinking about getting some other localities too, like Gasquet).
Yeah, I would be expecting some variation in any seed lot.
As for the label "Red Tongues", I would assume that the mother plant, that the seeds were collected from, would have the blood red fishtail appendage.
Barry Rice is his CP book mentioned different variances in pigmentation patterns with these plants.
One type pattern he labled as "Crimson fangs", describing them as "fabulously beautiful".
There is in how they grow. Mountain plants are far more tolerant of high temperatures, low humidity, fluctuations in water level, etc. The coastal forms are used to constant cold water, low temps, high humidity, etc. and expect it in cultivation, at least from all I've read.
In the first edition of
The Savage Garden, the author notes that most
Darlingtonia in cultivation are the coastal variety.
That may explain some the problems these plants are having in cultivation.
It seems the coastal variants have a narrower window of tolerance than the mountain varieties do.
Whereas, the mountainous forms can experience summertime highs into the high 90s, and on the other hand experiencing snow loads in the winter.
The coastal forms, average a consistent 67F according to one source I read.
So, although the coastal types experience less drastic temperature swings, they also seem to be less tolerant of being outside their narrow comfort zone.
