Also known as mother-in-law's tongue, this hardy indoor
variety excels as an air-cleaning plant, capable of removing benzene, formaldehyde,
and trichloroethylene. Snake plants love a sunny corner, though they can tolerate
low light as well. Just be sure not to overwater it — wait until the top inch of soil
is dry before dousing. It's much easier to overwater this plant than underwater it.
