What is the Dieffenbachia Plant?

Dieffenbachia is a houseplant usually seen in homes and office spaces around the world. These plants add a tropical vibe to any interior they are made a part of. Commonly known as the “Dumb cane” or “Mother-in-law’s tongue” because of its toxic sap, if ingested the sap can cause temporary muteness because of its effect on the vocal cords.

A tropical evergreen plant from the Araceae family, the dieffenbachia plants are native to Mexico, the West Indies, and the South of Argentina. With several variations of the Dieffenbachia plant, it is usually known for its variegated creamy white and green foliage, and its rare lily-like flowers.

Some of the leaves can be striped, other speckled or splashed in appearance. Usually taken as a plant for all spaces and sizes, the dieffenbachia can grow from 12 to 14 inches to up to 6 feet tall depending on its type.

Is Dieffenbachia An Air Purifier?

The short answer is ‘yes’. Dieffenbachia is one of several house plants that have been scientifically proven to control and improve indoor air pollution. It is always on the list of top 10 plant air purifiers and as per a Malaysian research study, it can absorb carbon dioxide really well.

In the experiment, it was seen to reduce initial CO2 levels of 436 ppm down to 332 ppm, and also reduced levels of other toxic compounds like xylene and toluene.

Both these compounds are known to play a part in a phenomenon called a sick-building syndrome, which results from spending too much time within a polluted structure. Symptoms of the syndrome and of toluene toxicity include feebleness, insomnia, fatigue, and even kidney and liver damage as per the United States Department of Labor.

To amplify the air purifying benefits of your dieffenbachia, you are best advised to place it within your personal breathing zone or your most frequented home space. This would ideally be a 6 to 8 cubic foot area where you spend most of your time. The age-old adage ‘the more the merrier’ goes really well here because the more plants you group together or strategically place all over your home or office, the better the results.

The NASA Study on Dieffenbachia

Apart from an Australian and a Malaysian study proving the effectiveness of Dieffenbachia as an air purifier, a 2013 study by NASA on environmental pollution also confirmed the same. Dieffenbachia was one of several air purifying house plants used in an experiment to understand how landscape plants help in indoor air pollution abatement.

In the study, parts of the plants such as leaves and roots as well as, its microorganisms were evaluated in their effectiveness to reduce indoor pollution. It was noted that plant roots and their relevant microorganisms absorb large volumes of pollutants including cigarette smoke, solvents, and even radon, and then destroy them. Eventually, the pollutants are converted into new plant tissue.

Other NASA tests confirm findings of the Malaysian study which claims that Dieffenbachia can absorb toxins from the air. They help purify formaldehyde, xylene, and toluene from our surroundings. We produce formaldehyde in our homes from paper towels, trash bags, tissues, carpet liners, and floor covers.

The Best Dieffenbachia Varieties for Your Home

There are so many types of dieffenbachia available that most homeowners and plant enthusiasts often wonder which one is the best amongst them all in terms of air purifying or easy management etc.

However, there is no best variant of the plant; ideally, you should go for a type that suits your spatial needs. Because as far as air-purifying is considered all the different types of dieffenbachia are excellent at fulfilling that purpose.

The most common variants available in the US are often chosen because of their size, appearance or aesthetic appeal. The Dieffenbachia seguine is one such popular variety, known for its height of up to 10 feet and clusters of large green ovate leaves. This type is often used as an interior element to ass a tropical vibe to any place.

The dieffenbachia maculate is another variation known particularly for its big variegated leaves that can be grown up to 8 inches long. The ‘Rudolph Roehrs’, is another variant that is prized for its yellow leaves with ivory splotches.

Dieffenbachia amoena is another common variety that grows to 6 feet in height and has huge 20-inch leaves. The Tropic Snow’, on the other hand, is popular for its smaller leaves and relatively more compact size.

Improves Indoor Air Quality

As discussed earlier, the dieffenbachia improves air quality by acting as an air purifier and absorbing harmful toxic compounds like acetone, benzene, formaldehyde, and toluene from the home. Exposure to these compounds can cause several adverse symptoms over time.

Best Co2 Absorber

Dieffenbachia is also an excellent carbon dioxide absorber and can greatly reduce its levels in the air. In a Malaysian study, dieffenbachia was top of the list amongst houseplants that could cleanse CO2 from the air.

Best Low Light Plant

Dieffenbachia can grow in all sorts of lighting. This makes it a popular choice in office settings where artificial lighting and enclosed spaces create a feeling of stuffiness. It can grow equally well in partial sunlight, open sunlight, and even full shade.

Easy To Maintain

Dieffenbachia is one of the most low maintenance houseplants that can survive in very minimal conditions related to lighting and watering. It can even be grown in the water!

Big Foliage

The big leafy appearance of the dieffenbachia has made it a popular choice for aesthetic reasons since the Victorian Era. Apart from adding a tropical vibe, it can also be used in formal office settings, or in casual home spaces. It all depends on perspective!

Care and Feeding

Since the Dieffenbachia is a tropical plant, it is sensitive to soggy soil. It’s is best watered slowly, so that it absorbs as much is required. It is important to check that the soil has dried out before each watering schedule.


Dieffenbachia loves humid weather, and if such weather conditions are not available where you live then you can always recreate them. Using a humidifier, keeping a pan of water close to the plant or placing the plant in a try filled with pebbles and water all help to maintain air humidity. You can even keep your dieffenbachia in the bathroom and it should do just fine with the humidity there.

If nothing else, then you should try to mist the plant once a week to help it grow.


These plants do need to be fed with fertilizer often to help them grow well. The most convenient way to add fertilizer to the plant is by dissolving a few drops of it in water. The easiest way to fertilize these plants is to add a few drops of water-soluble fertilizer in the water when watering it. However, make sure not to fertilize the plant during the winters.


Dieffenbachia is commonly known as dumb cane because of the temporarily mute effect it can have on your vocal cards, if ingested. The oxalic acid and asparagines proteins found in the plant cause this reaction and are also responsible for the burning sensation when the juice of the plant touches the skin.

Although the toxic effects of dieffenbachia ingestion are temporary, the plant is still placed in the medium toxic range, and therefore, care is required especially around children and pets.
