Plants for a Small Bedroom: Where They Actually Fit

by

In a small bedroom the plant almost never gets the window, so choose for the surface it will actually sit on rather than for the direction the room faces. A nightstand, a dresser and a floor corner are all several feet from the glass, which puts them in University of Illinois Extension's medium band at about 150 foot-candles or its low band at about 75, whatever the compass says. And the second thing nobody accounts for: a bedroom window spends much of the day behind a curtain, which subtracts hours the chart assumed you had.

Your curtains, not your compass, set the light budget

Every window-direction chart ever published assumes an uncovered pane. A bedroom is the one room where that assumption is usually false, and it is false for reasons you will not change for a plant.

Blackout curtains on a bedroom window are the point of blackout curtains. A ground-floor or facing-the-street bedroom keeps its blinds half closed for privacy all day. A person on a night shift sleeps through the brightest hours with the room shut. In each case the window's direction is accurate and irrelevant, because the light arrives while the fabric is in front of it.

Count the hours your bedroom window is genuinely uncovered on a normal weekday, not an ideal one. If the honest answer is three or four hours, treat the room one full band lower than its exposure suggests and pick from the low-light group.

Where a plant fits in a small bedroom

Small bedrooms have four candidate surfaces and they are not interchangeable. Distance from the glass is what separates them, and Illinois Extension's bands turn that distance into a light level.

Surface Typical position Illinois Extension band at that distance Realistic plants
Windowsill On the glass Bright to direct, depending on exposure Sun plants only, and only if the curtain stays open
Nightstand A few feet from the window, often beside the bed Medium, about 150 foot-candles at an east or west window Spider plant, parlor palm, heartleaf philodendron
Dresser or chest Usually on the wall opposite the window Low, about 75 foot-candles at 3 to 10 feet ZZ plant, snake plant, cast iron plant
Floor corner The darkest usable spot in the room Low, and lower again behind an open door Cast iron plant, or a rotation slot rather than a permanent home

The pattern is worth saying out loud. In a small bedroom the plant is a low-light plant by geometry, not by preference, and the reason is that the bed takes the floor area next to the window.

The bedroom plant claims, checked

The reason most people search for a bedroom plant is a health claim, so it deserves a straight answer rather than a repeated one.

Researchers Bryan Cummings and Michael Waring at Drexel University reviewed a dozen studies spanning 30 years of research and published the result in the Journal of Exposure Science and Environmental Epidemiology in 2019. Their finding was that natural and ventilation air exchange rates in homes and offices dilute volatile organic compounds much faster than plants extract them, and that it would take between 100 and 1,000 plants per square meter of floor space to compete with the air cleaning capacity of a building's air handling system or even a couple of open windows.

Note what that does and does not settle. It addresses volatile organic compounds in real rooms with real ventilation, and it says a normal number of houseplants is not an air treatment. It says nothing about whether you enjoy the room more with something green in it, which is a perfectly good reason to want one and the reason this guide assumes.

The temperature nobody checks

Here is a bedroom-specific factor that never appears in a bedroom plant list, and it is the one most likely to be working against you.

University of Georgia Extension gives the best temperature range for indoor plants as 70 to 80 degrees Fahrenheit during the day and 65 to 70 at night. A lot of households deliberately run the bedroom colder than the rest of the home for sleeping, and a bedroom with the radiator valve turned down or the vent closed can sit below that night range for most of the heating season.

That does not kill a cast iron plant. It does mean a bedroom is a slower room than the living room for the same plant at the same distance from a window, and it is worth knowing before you conclude that the plant is sick. If your bedroom is the cold room in the apartment, the tropical foliage goes elsewhere and the tolerant group stays.

The foliage that suits the position

Once you accept that the nightstand and the dresser are medium and low light, the plant list is short and it is not a compromise.

For the dresser and the darker half of the room, University of Maryland Extension's low-light group is ZZ plant (Zamioculcas zamiifolia), snake plant (Dracaena trifasciata), cast iron plant (Aspidistra elatior) and peace lily (Spathiphyllum wallisii). Clemson Extension adds Chinese evergreen (Aglaonema commutatum), golden pothos (Epipremnum aureum) and parlor palm (Chamaedorea elegans) to the same band.

For a nightstand within a few feet of an uncovered window, Clemson's medium-light group opens up: spider plant (Chlorophytum comosum), Boston fern (Nephrolepis exaltata), schefflera (Schefflera arboricola) and English ivy (Hedera helix), which it places within several feet of a bright source or in an eastern exposure. Heartleaf philodendron (Philodendron hederaceum) suits the same distance and trails off the edge of a small surface instead of taking up space on it.

Two things a bedroom should not get

Scale is the first. A small bedroom has less clear floor than any other room in an apartment once the bed is in, so a tall floor plant is usually a doorway obstruction rather than a feature, and the honest options are one plant on a surface or one narrow plant in a corner that is not on a route you walk at night.

The second is scent. Fragrant flowering plants are a genuinely different subject with different light and care needs, and they are outside what this site covers. This guide is foliage only. If a scented plant beside the bed is what you are after, a university extension service's flowering houseplant pages are the place to research it, and the light requirements there will be higher than a dresser can supply.

Where the bedroom plant should have gone instead

If you have read the distances above and concluded that your bedroom cannot support the plant you had in mind, that is a normal outcome and there is a better answer than forcing it.

Move the plant to the brightest position in the apartment and keep the bedroom for the tolerant group. The spot-by-spot map of an apartment sets out which room actually holds the light. If the bedroom is the only room with a window at all, its direction matters more than usual, and the difference between a north-facing window and an east-facing one is the difference between a shelf's worth of usable light and most of the room's.

Pets, children and a plant beside the bed

A nightstand is within reach of a cat that jumps and a toddler who climbs, which makes a bedroom the room where this question is worth one plain paragraph. Check any plant against the ASPCA's toxic and non-toxic plants database before it enters a home with a cat or a dog. For a child's room, or if a child has eaten part of a plant, the free 24-hour Poison Help line funded by the US Health Resources and Services Administration is 1-800-222-1222, and it connects you to your local poison center. Which specific plants are toxic to which animals is not this site's subject and is not guessed at here.

FAQ

What plants are best for a bedroom?
The ones that suit a surface several feet from the window, because that is where a small bedroom's plant ends up. Maryland Extension's low-light group covers ZZ plant, snake plant, cast iron plant and peace lily; Clemson Extension's medium-light group, including spider plant and schefflera, works on a nightstand within a few feet of an uncovered window.

Do plants in the bedroom improve air quality?
Not at any scale you would keep in a bedroom. Cummings and Waring's 2019 review in the Journal of Exposure Science and Environmental Epidemiology found ordinary air exchange dilutes volatile organic compounds far faster than plants remove them, and estimated it would take between 100 and 1,000 plants per square meter of floor to match a building's ventilation or a couple of open windows.

Is it safe to sleep with plants in the bedroom?
There is no evidence problem with keeping foliage plants in a bedroom, and the air-quality claims made in either direction are the same overstated claims. The real questions are practical: whether the plant is within reach of a pet or a child, and whether the room is bright enough and warm enough for it.

How much light does a bedroom plant need?
Less than the room's exposure suggests, because the curtain subtracts hours the chart assumed. Illinois Extension's bands are about 150 foot-candles for medium light a few feet from an east or west window and about 75 for low light 3 to 10 feet back, which is where most bedroom furniture sits.

Can a plant live in a bedroom with no window?
Not permanently. Georgia Extension's insufficient-light symptoms, starting with no growth and stretched new stems, arrive in any room with no natural light, and the published answer for a dark spot is rotation rather than a hardier species.
