Flora & Fauna Podcast Episode 5: Houseplants

House plants clean the air of chemicals, dust and other pollutants. Some specialize in the chemicals they prefer: English ivy, peace lily and Chinese evergreen will clean up benzene and formaldehyde; the spider plant and weeping fig will pull formaldehyde, xylene and toluene out of the air; the variegated snake plant and red edged dracaena will clean up benzene, fomaldehyde, tricholorethylene and ammonia from the air. 

Darryl Cheng is an industrial engineer who became interested in houseplants a few years ago. He would do time-lapse videos of his plants on social media, and that led to a huge Instagram following and book deals, including his popular book The New Plant Parent.
