Help a noobie pick plants, please!

Hi guys, I came here from the dendroboard because you folks seemed just the people who can help me with my problem.

OK. I have zero experience with terrariums and I have never grown a plant in my life. I am setting up a PDF tank right now. Plumbing, construction..I can handle that. But my wife wants it pretty, preferably with flowers. Sheesh.
And there is another problem. My tank is an odd shape: 20" square by 30" high. I can't pump a lot of light into it without heating it up. Since I live in Georgia I am already going to have a lot of problems with heat, so I am sticking with PC's.

So...I need to know some good vivarium plants that will do well, (and preferably have flowers) in lowish light. I asked this elsewhere and I got confusing answers, like "get pothos". What in the world is a pothos? I looked at PDF plant sellers and never saw a pothos anywhere. So if anyone, please, could give me the names of some lowlight species and some info on where to find them, I would be SO grateful. If I do it well, the wife will let me put tank in the living room instead of down in the dungeon (basement).

There's a lot of guys on here pretty knowledgeable about plants so I'm sure they'll jump in here to help, meanwhile although I don't think I'd be the best person to tell you what plants to get, I can tell you what pothos is. I have it in my tanks and it grows well but it doesn't flower. It's a vine type of plant. Some call it a money plant. It has spadish shaped leaves that grow a couple of inches apart on the vine.


Edit: The plant with the stem going into the water in front of that big branch is Pothos.

There's actually quite a few names for this one plant.

I know:

Devil's Ivy
English Ivy

Pothos and heart-shaped philodendrons will be the easiest of all. Both grow in water or soil and under lights (daylight ,5000k,compact flourescent bulbs). Coffee, arubas, dwarf spathiphiums(spelling?), small bromelias, fig ivy, antheriums and the small philodendrons, all of which can be found at you local nursey or even Walmart at sizes to fit terraiums. Unfortunally plants bloom when big and in higher lights. Of the plants listed ony the spaths will bloom in an terraium. My pothos bloooms occassionally but it has 2 1/2 foot leaves an is 15' long.
