Ok, from a brief look into this before (I am in no way an expert) I think you would need to define what you see as a problem with indoor plants. Is it lack of light? As a quick and not too detailed answer, take a look at the typical plants you see around offices - dracaena is one that comes to mind. I think it handles relatively low light and has the benefit of reducing mould particles in the atmosphere. Ficus is another one that I have had indoors and is really difficult to kill, though mine is outdoors now. (As for easily maintained, I have had some dracaena before and they are pretty easy, but in both ended up getting some sort of disease after a couple of years).
