I know this is an older topic that I happened to stumble upon, but I wanted to mention that Texas does have a Carnivorous plants Facebook group that has a few knowledgeable growers that do quite well growing them in that state. Maybe they can be of help to others looking for info growing these plants in Texas. Here is a link to that site:
