I agree, this has been an excellent discussion of Darlingtonia cultivation. The cultivation differences between the successful growers are significant and I am very curious to see what the biological basis for these differences are. Hopefully, an understanding of these phenomena will lead to more successful cultivation of Darlingtonia on the east coast of U.S.
I can tell you that outside cultivation of Darlingtonia in wet or moist sphagnum has been unsuccessful here. Perhaps our problem is bacterial or fungal pathogens not found or active in the areas where other growers have been successful.
I wanted to follow-up with some a couple of photos of our plants during summer. This is a photo page where we discuss humidity with a couple of our Darlingtonia pots and other plants. cobraplant.com/gallery/Humidity/humidity.html
