House plants are such a simple and easy way to go green. They liven up your decor and they're great for the air you breath. Just look at this lovely overgrown kitchen, it makes the whole house feel a little more earthy. And with so many inexpensive options, I like spider plants, you can have them all over the house. Just a little water and some sun and they're happy as can be. I also keep a lovely money tree around, from IKEA! The funny thing is the day after we got it my boyfriend and I fell into almost $4,000! Coincidence, maybe, but I prefer to think my little plant works.
