Does Croton plant purify air?

Croton plants, also known as Codiaeum variegatum, are popular houseplants appreciated for their striking foliage. With their vibrant colors and patterns, they add a pop of color to any space. However, in recent years, there has been a growing interest in their air-purifying abilities. In this blog, we will explore the question “Does Croton plant purify air?” and look at the scientific evidence behind this claim.

What are Air-Purifying Plants?

Air-purifying plants are indoor plants that have the ability to remove harmful pollutants from the air, such as benzene, formaldehyde, and trichloroethylene. These chemicals are commonly found in indoor environments and are known to cause health problems such as headaches, respiratory issues, and even cancer.

According to a study by NASA, certain plants have the ability to remove these harmful pollutants from the air by absorbing them through their leaves and roots. The study found that plants such as peace lily, spider plant, and bamboo palm were highly effective at removing these toxins.

Croton Plant: Aesthetic or Air-Purifying?

Croton plants are known for their colorful foliage, which ranges from bright greens and yellows to oranges and reds. They are native to Asia and the Pacific Islands and have been grown as houseplants for centuries. While they are popular for their aesthetic appeal, there is little scientific evidence to support their air-purifying abilities.

In a study conducted by the University of Georgia, croton plants were found to have no significant effect on indoor air quality. The study measured the levels of benzene, formaldehyde, and trichloroethylene in a sealed chamber with and without croton plants. The results showed that the croton plants did not reduce the levels of these pollutants in any significant way.

Another study published in the Journal of Environmental Horticulture found that while croton plants did have the ability to absorb certain pollutants, they were not as effective as other air-purifying plants such as spider plants and golden pothos.

The Benefits of Croton Plants

While croton plants may not be as effective as other air-purifying plants, they still offer numerous benefits for indoor environments. For example, they are low-maintenance and easy to care for, making them ideal for beginners. They are also versatile and can be grown in a variety of indoor settings, from bright and sunny to low-light conditions.

In addition to their aesthetic appeal, croton plants are also known for their ability to boost mood and reduce stress. The vibrant colors and patterns of their leaves are thought to have a calming effect on the mind, making them a popular choice for offices and other workspaces.


While croton plants may not be the most effective air-purifying plants, they still offer numerous benefits for indoor environments. They are low-maintenance, versatile, and have been shown to boost mood and reduce stress. If you are looking for an air-purifying plant, however, you may want to consider other options such as spider plants, bamboo palm, and golden pothos, which have been shown to be more effective at removing harmful pollutants from the air.
