Having good sleep hygiene is essential in our always-on, tech-obsessed, Netflix-bingeing-in-bed, night owl society. But even if you follow the recommended bedtime “rules,” getting a restful night’s sleep can be elusive. Instead of turning to pills and potions, give a little indoor nature therapy a try. Numerous plants are experts at improving air quality and encouraging relaxation with certain varieties known for eliminating toxins, emitting oxygen, and absorbing carbon dioxide and fumes. Plus, having some green around will naturally perk you up; for city dwellers, a bedside pot may be your only connection to nature. Read on for 11 of the best indoor plants to help you make the most of your sleeping hours—plus, another three to avoid. Take special care if you have curious pets and children; some of these helpful plants are no-nos for little creatures who will put anything in their mouths.
Known for its calming and soothing properties, lavender is a go-to ingredient in aromatherapeutic oils, scented candles, and body care products. Go for the real deal, and usher in a dreamy sleep by keeping a plant bedside—just make sure this sun-thirsty plant gets plenty of light. There are numerous lavender varieties, but French lavender has a reputation for being one of the easier varieties to grow indoors. Imagining yourself frolicking in a field in Provence will also help lull you to sleep.
Snake Plant (aka Mother-in-Law’s Tongue)
While few of us actually want our mother-in-law (or her tongue) anywhere near our bedroom, this amusingly nicknamed plant is a welcome addition. In addition to filtering habitual toxic offenders (like formaldehyde), the snake plant releases oxygen at night while simultaneously taking in carbon dioxide.
The transporting fragrance of jasmine is exotic and heady yet cozy at the same time. The scent can be on the strong side for some, so consider putting this visually beautiful climber at least a few feet away from your bed. The flowers themselves bloom over the course of weeks, lending a steady scent that also has been shown to reduce anxiety levels.
Christmas Cactus
Included in the cactus family because of its ability to store water, the “Christmas” variety is much more whimsical and colorful than the spiny, needle-covered desert versions that typically come to mind. In addition to producing lovely flowers in December, Christmas cacti are excellent air purifiers—just make sure you strike the right hydration balance.
Aloe Vera
Aloe vera is a great, easy-to-maintain plant for brown thumbs, and it serves numerous purposes. In addition to purifying the air and releasing oxygen, this succulent is useful if you forget to moisturize or burn yourself. Simply snap off  the end of an “arm,” and rub the gel to soothe the spot and help it heal.
Fragrant yet not overpowering, gardenias are a scented, flowering sleep aid. Novice gardeners should know that they can be divas, requiring a careful balance of light and humidity. Gardenias should also be kept away from drafts and direct sources of hot air. The payoff for these high-maintenance beauties could be better z’s: An organic compound found in gardenias has historically been used in traditional medicine and has been found to promote sleep and to reduce anxiety in more recent studies.
Spider Plant
Although they are not the most showy of indoor plants, what spider plants lack in glam, they make up for in pollutant-fighting abilities. This humble greenery ranked best at removing formaldehyde from the air by a NASA study. Spider plants are also pros at absorbing odors. We can all rest easier when we know our bodies aren’t ingesting potentially toxic chemicals.
English Ivy
Like the spider plant, English ivy was named a top air cleanser for chemicals, and it also makes quick work of airborne mold. Since the sniffling, sneezing, eye-irritating effects of allergies and asthma can have a big impact on sleep, this plant is a no-brainer and poetic-looking addition to your bedroom. Just keep it away from dogs, cats, and kids.
Red Edged Dracaena
Although the red edged dracaena’s roots are in Africa, you can find it at many local garden stores throughout the U.S. It’s hardy, adds an unexpected dash of red, and is efficient at removing yuckies like formaldehyde and VOCs. Red-edged dracaena can grow up to 15 feet, so be sure to leave it ample space to stretch and suck up all those pollutants.
Gerber Daisies
Gerber daisies are a perennial favorite for cheerful arrangements, so just imagine the sunny effect they will have on your mood if you keep them bedside. Every time you wake up from your (hopefully restful) night’s sleep, it will feel like someone just gifted you with a blooming bouquet. Bonus points for the way these plants remove benzene, absorb carbon dioxide, and release oxygen, which could make it easier for you to breathe. Just make sure to keep it in a sunny spot.
Peace Lily
Want a low-maintenance plant that doesn’t need a ton of watering or sunlight? The Peace lily could be your girl.  Peace lilies were another high ranker in NASA’s study—they remove toxins like benzene and formaldehyde from the environment. These perennials also release small amounts of moisture while removing airborne microbes so your sleep isn’t disturbed by certain allergens. Keep the Peace lily away from kids and pets, and take notice when her flowers droop and get her a drink, and you’ll have a happy bedroom addition for years.
Plants to Avoid: Oleander, Dumb Cane, Caladium
Oleander (pictured above) is a flowering shrub that grows well indoors, but it tops the list of poisonous plants; all parts of oleander (including its sap) can be fatal if ingested. If you are living without kids or pets, this pretty plant can be used decoratively, but we’d keep it out of the bedroom: No one needs to worry about bumping into it in the middle of the night. Caladium is another plant to steer clear of in the bedroom, especially if you have little humans or animals around. Along with being poisonous, it could provoke a reaction in those with sensitive skin. Finally, although chewing the leaves of a Dumb Cane sounds less than appealing to most of us, it’s another plant we won’t be picking up at the garden store. Symptoms of Dumb Cane poisoning include burning mouth or throat and damage to the cornea. While claims of its toxicity may be dramatized, there are simply too many other, less poisonous plants around for us to lay awake at night worrying about exposure.
