Wax Begonia

(Begonia semperflorens)
Place in an area with abundant sunlight and this semiwoody succulent will produce pretty clusters of flat white, pink, or red flowers during the summer.

How it Helps: The wax plant is a heavy hitter in filtering out benzene and chemicals produced by toluene, a liquid found in some waxes and adhesives, according to a University of Georgia study conducted last year.
