I got the plant from cobraplants.com a few weeks ago. It had its first pitcher. THe plant is a S. Leucophylla. But suddenly, the pitcher started browning and the leaves lost their toughness. WHat happened? There doesn't seem to be any pests. I grow my plant in my backyard in San Jose, California. It receives little to no shade and gets a lot of light for the rest of the day. Its on a tray system and always make sure there is some water in it.
Just a guess. The plant may be experiencing transplant shock. If the roots were disturbed, it often takes several weeks before new root growth can keep up with transpiration demand. This results in loss of tugor and wilting, even if the soil is wet. If cobraplants.com was growing the plant in a greenhouse, placing the plant in direct sun may sunburn the leaves. When getting a new plant or repotting a plant, it is best to put it in the shade for a week or so and then gradually introduce it to more harsh conditions.
I agree with Bob on "easing" any newly acquired plant into your own growing conditions... Also as Aidan had mentioned, you are exposing the plant to leaf burn and probable fungus infections as well, by keeping it too wet and hot without a new healthy supportive root system. In my opinion, slightly drier growing media and some shade from the hottest part of the day may help you until the plant has become established and "happy" You may want to also trim off all dead growth as a precaution. Happy Growing, Brian.
Ya. Watch the water. I'm trying out a new method of watering right now and when I mess up and let some plants get too dry they start wilting. Fix the watering up and it should come right back though. Sarracenia are pretty tough plants in my experience.
