Evergreen plants are a popular choice for many gardeners and landscapers due to their year-round foliage and low maintenance requirements. But have you ever wondered how much oxygen these plants produce? In this article, we will explore the oxygen production of evergreen plants and their benefits to our environment.

The Role of Plants in Oxygen Production

Plants play a vital role in the Earth’s atmosphere by producing oxygen through photosynthesis. During photosynthesis, plants use energy from sunlight to convert carbon dioxide (CO2) into oxygen (O2). This process not only produces oxygen but also helps to remove harmful CO2 from the air, making it cleaner and healthier for us to breathe.

Oxygen Production of Evergreen Plants

Evergreen plants are known for their ability to retain their leaves throughout the year, unlike deciduous plants that shed their leaves during the fall season. This means that evergreen plants have a longer period of time to produce oxygen compared to deciduous plants.

According to research, evergreen plants can produce anywhere from 5% to 10% more oxygen than deciduous plants due to their longer leaf retention. However, it’s important to note that the amount of oxygen produced by a plant depends on several factors such as its size, age, and growth rate.

Benefits of Evergreen Plants

Apart from producing oxygen, evergreen plants provide numerous benefits to our environment. Here are some of them:

Carbon Dioxide Absorption

As mentioned earlier, plants absorb CO2 during photosynthesis. Evergreen plants can absorb CO2 throughout the year, making them great carbon sinks that help reduce greenhouse gas emissions.

Air Purification

Evergreen plants can filter harmful pollutants from the air, such as formaldehyde and benzene, which are commonly found in household items like furniture and cleaning products. By removing these pollutants, evergreens can improve the air quality in our homes and communities.

Wildlife Habitat

Evergreen plants provide shelter and food for wildlife, such as birds and squirrels. Their year-round foliage also serves as a hiding place for small animals, protecting them from predators.


Evergreen plants are an excellent addition to any landscape due to their aesthetic appeal and numerous benefits to the environment. Not only do they produce more oxygen than deciduous plants, but they also absorb CO2, purify the air, and provide a habitat for wildlife.

So, the next time you’re choosing plants for your garden or landscaping project, consider adding some evergreens to your list. Not only will they enhance the beauty of your space, but they’ll also contribute to a healthier planet.


Do all plants produce oxygen?

No. While most plants produce oxygen during photosynthesis, some plants like succulents and cacti produce very little oxygen due to their unique adaptations to arid environments.

How much oxygen does a single plant produce?

The amount of oxygen produced by a plant depends on several factors such as its size, age, and growth rate. On average, a mature tree can produce enough oxygen for two to ten people in a day.

Can evergreen plants survive in all climates?

Evergreen plants can thrive in a variety of climates, from tropical to subarctic regions. However, it’s important to choose the right species that can tolerate the specific climate conditions in your area.
