The book I have and these sites/videos are focused on cleaning the air and don't mention nitrogen fixing. It would be interesting to find out which of these do fix nitrogen.
Maybe someone knows of some low growing nitrogen fixer that survives on as little light as a house plant. Some kind of clover?

Subject: House plant permaculture
Here in my cube I have two rubber trees and a dracaena plant. One rubber tree is about 13 feet tall, the other is about 6 feet tall. My cube is 6'x8' so the trees reach over the aisle and my neighbor's cube. Everyone here thinks they are great.
Can anyone think of any good companion plants for these? There is plenty of space in the pots for additional plants. They would obviously need to be tropical plants.
Something that stays fairly small and fixes nitrogen would be ideal.
