I have to agree with wyld on this one. You can't make a general statement about "plants".
If you are thinking amazon, I'm assuming you want plants from the amazon. If you've ever been there, there is a lot of subdued lighting (note, not all). So most of the plants are relatively easy to care for. You might even be able to get away with your existing fixture (granted to put in some bulb with color temps suited for plants).
I think it's Monga Bay that has some pretty detailed biotope descriptions that will set you up with fish, plants and decoration recomendations.
