Thought I'd post a couple of pics of my Darlingtonia, just recently put into it's winter dormancy.
This Cobra was obtained back in 2007, and it has successfully gone through two winter dormancies, and is now entering it's third with me. I grow it in the basement under a 42 watt 6500k CFL. And last spring, I repotted it into a 13" plastic pot. A top dressing of lfs lies atop a coarse mineral mix, similar to my mexi-ping media, but with more peat and lfs added in to it. For watering, I usually just dump a tray of ice cubes onto the topdressing.
This plant took a growth spurt earlier this fall, when I made an effort to get more D. hydei onto the plant. I figure with the extra protein, it decided to go for and make some bigger pitchers. The tallest pitcher is currently 8.5 inces.
For dormancy, I just place the Cobra out into our heated garage. We keep the thermostat turned down low, but it doesn't usually get too much below 7C out there in the winter.
I was surprised that Darlingtonia keeps it's pitchers as long and as well as it does. In the two and some years that I have had it, I haven't had to remove a pitcher yet. The pitcher in the bottom left with the browning crown, was the large pitcher it came with back in '07.
