Plants for a Windowless Bathroom

A reader in Kansas City wants a plant for a second-floor ¾ bath with no windows, temps 65–75°F, on a shelf above the toilet.

Light is the only limiting factor. Without a fluorescent light left on 6–8 hours daily, no plant will survive long-term—it will slowly decline.

A ZZ Plant (Zamioculcas zamiifolia) might last 6–12 months in such low light, but even it will eventually deteriorate.

Install a timer-controlled fluorescent fixture for any real success.
