Well I've placed my cobras into a bigger pot and I think I'm on top of the thrip!!!?? I've also had my seeds out of stratification for two weeks and already I've noticed some of the seeds have germinated. Oh, I can't resist: trimmen1000, when you wrote "I think these are my favorites so far. These are from California Carnivores". Are you talking about the cobras in the foreground or the legs in the background? ? I hope I'm not being too cheeky. Dave.

Here's an update on Barry's othello and typical cobra seeds I stratified in June and have sown out in the greenhouse a month later.
I've gotten both types to germinate at about 75% and are now growing strongly. Some of the earliest to germinate are producing their first leaves. It will be interesting to see how long it takes for them to produce their first juvenile pitchers.
The others that didn't germinate I lost to mould, these guys tended to be smaller than those that germinated so I think they were inferior anyway.
It's great to see how things grow and develop from scratch.
Now I just have to be patient and wait for them to send out their first mature traps in two or three years time.
Further posts with photos to come.
Dave.

Radjess331,
Are you concerned that the seedlings may suffer during winter if they are germinated late?
Dave.

I've heard that you can grow sarra seeds under grow lights on a 24hr cycle for the first two growing seasons which makes them grow faster but I don't know if this would apply to cobras.
I can't see why not.
So if you're afraid the seedlings might not survive a harsh winter you could give the above a go.
Dave.

So say'eth one living in England BTW, it gets hotter in the USA and many other places for longer periods than it does in the UK. There are plenty of places, like right in the mountains in PA, NY and NJ where Darlingtonia could be cultivated without much trouble. In the Poconos, many people have seeps running right on their property along with Sphagnum moss and it would extremely easy to naturalize Darlingtonia. It is consistently 10-15 degrees F. cooler in the Poconos then here in lowland New Jersey this profound change in climate is only 40-60 miles away. Not sure they would survive winter though... The cool root issue is very much over hyped. As long as it is in a large enough pot,. with a high water table, it will be fine even in scorching sun. Yes, that is because water has a tremendous ability to absorb heat, which is why the weather/temperatures on your island are so much more stable than they would otherwise be.

New update on the thrip: After repotting I fully imersed the pot in a bucket of water until the thrip floated to the surface. I skimmed the little buggers off and pulled the pot back out of the water and I've noticed a vast reduction in damage to my cobras this season. The plants are looking much happier and have thrown out some great strong new growth. Here's some pictures I promised as a follow up. Enjoy. Dave.

OMG! what a fantastic cobra Dave. I got 2 nice 2-3 inch seedlings from a good friend on OCPS in oct. One of them died and none grew at all. One totally became dry and crisp. However...I notice today that the smaller one has actually a small red nub coming up. I guess it took 3 months to recover from repotting. Is this normal? It just sat there for 3 months. Also how fast do these things grow? how long before a pitcher forms from start to finish?
thanks,
V

Sad news,
We had a string of really hot weather a few weeks back and all my cobra seedlings died! I'm particularly sad about the loss of my 'Othello' seedlings, I was really looking forward to seeing them develop and having the yellow flowers.
Jorick, I tried your suggestion of putting the pot into water about half way up the side of the pot. This has worked really well and the larger cobras took the 44 deg C day without too much problem.
The whole thing is placed under a bench and this keeps the hot sun off the top of the pot and helps to keep the sphagnum cooler on a hot day. They don't seem to mind the lower light levels either, and they've kept their good colour.
I've used a styrafoam box to hold the water and this seems to help keep the water cool and in turn this keeps the roots cool enough to fend off the heat.
About the worst that happes is the cobras tongues turn brown at the tips.
Vraev, my personal view is that my cobras grow quite quickly, mine were only two years from germination before they sent up their first mature traps. 12 months later and the tallest trap is about 4-5 inches tall.
When I repotted, I simply placed the contents of the smaller pot into a bigger one and then poked new sphagnum around the root ball. They didn't slow down their growth and didn't go backwards so I can't tell you if what your guys did is normal.
I also had one plant that was particularly touchy with the heat and slowly died back over a 12 month period. Plus I had real problems with thrip. This cobra continually tried to send up new growth but I think the roots had died and it was only being kept alive by the humidity in the GH. It has since gone to CP heaven and I have two cobras left out of my original 6 seedlings I bought three years ago.
Dave.

Hmmm....really sad to hear that Dave. Hmm....that is pretty fast considering how slow neps can be. how about growth of each pitcher? 3 weeks or so? Well....there is a high possibility that the little guy seems to be recovering. Hopefully he survives and likes what I can offer for now.. Next summer I might try putting him outside.

I couldn't say for sure how long it takes for one trap to grow and open.
I would have to say it does take some weeks but I haven't really paid that much attention.
Perhaps someone who has bigger plants could help you out with that one.
They could also say if it takes longer as the traps get bigger.
Good luck with your little guy who seems to be recovering nicely.
Dave.
