VFT'er...
Fellow Texan, you are blessed to live in our state!
Here is the deal, you may not know it, but you live in the same city as these forums originate from, Phil and Jeff are located in Houston Texas.
1st, you have humidity as your ally... cause every one knows that humidity wise, Houstin is the armpit of texas... this is good for BOTH plants...
You will do with Sarracenia outdoors in a mini-bog, pot in saucer, or in an in-ground bog. I grow Sars in San Antonio, and they love what sun I am capable of giving them on my apartment window.
Sarracenia Flava and Purpera are native to Texas, though the clones you can get may not be from here. You can grow them easily outdoors, and if your interested, you could go to the big thicket and view them on pitcherplant trail. *just don't take any!*
Nepenthes are awesome plants, my favorite.. unfortunately, I have not had any success with them at all outdoors here, the few I have tried in my shadiest spots, all turn to crisps in no time flat... now, with your higher humidity, you may have a chance outdoors, but you still have texas heat, and I don't think that is something easily overcome for a nepenthes...
If you are going to grow indoors though, get yourself something easy, like Pyro said, and have a shot at it. Should be no problem there.
