Chinese Evergreen Eileen, aka Aglaonema Eileen, features green leaves that are heavily patterned with cream with an occasional splash of pink. The Chinese Evergreen family is among the top houseplants that purify the air and is also on Nasa's list of air-purifying plants. They have been found to be excellent at removing benzene and formaldehyde from the air inside your home or office! Not only that, but they are a rather hardy tropical, where they can handle most light and watering conditions.
