If you can replicate its natural environment closely, you can grow it. Research the weather patterns, Darlingtonia's ecological niche in the wild, see if others in your area can grow it, and try to mimic their setups (if any).
Second that advice. The big thing with cobras that I have found is don't let them get too hot- particularly their roots. Also, how big are they? That could determine a lot about what set up is appropriate. I have some seedlings right now, and I have having some trouble keeping them alive even though I have been successful in the past with mature plants.
Hey mantis- love the avatar! I think S. flava is my favorite sarracenia species. Have you seen S. moorei? I plan to post photos of my collection soon here, I will have my S. Moorei up.
Thanks. It's a S. flava var. atropurpurea I've had for about 2 years. In the spring, when its first big crop of pitchers arrives, its color is stunning - yet, with each passing week, it seems to lose more and more of that color until it looks like a faintly blushed var. rugelli. A funny but disappointing habit...
And I also like most of the S. xMoorei plats. I believe S. 'Adrian Slack' is a xMoorei backcross or something along those lines, isn't it?
Okay thanks for the advice, I've had my cobra for about 3-4 years but I'm not sure how old it was when I bought it let me know if anyone can determine the age from a photo, if so I will post one. Thanks hamata95
