I already own Sensevieria Laurentii ("mother-in-law's tongue") plants. This study makes me want to buy Gerbera Jamsonii (Gerbera daisy), Dracaena Deremensis ("Janet Craig" and "Warnekei"), Dracaena Marginata, and Epipremnum Aureum (Golden Pothos), since they are excellent at removing toxic chemicals commonly found indoors, plus these plants are known to be relatively easy to grow.
