How Much Oxygen Does Freesia Plant Produce?

Updated: April 18, 2022

Freesia is a perennial flowering plant that belongs to the Iris family. It is native to South Africa and is grown as an ornamental plant in many parts of the world, including the United States, Europe, and Asia. Freesia plants produce beautiful and fragrant flowers that come in a variety of colors, including white, yellow, pink, red, and blue.

Apart from their aesthetic value, freesia plants also have significant environmental benefits. One of the most notable benefits is their ability to produce oxygen. In this article, we will explore how much oxygen freesia plants produce and their impact on the environment.

How Much Oxygen Does Freesia Plant Produce?

Freesia plants are known to be highly efficient oxygen producers. They use the process of photosynthesis to convert carbon dioxide into oxygen. During the day, they absorb carbon dioxide from the air through their leaves and release oxygen back into the atmosphere. This process is critical for maintaining a healthy balance of oxygen and carbon dioxide levels in the air.

The amount of oxygen produced by freesia plants depends on several factors, including the size and age of the plant, its location, and the intensity of sunlight it receives. However, research has shown that a mature freesia plant can produce up to 30-40 liters of oxygen per day.

Environmental Benefits of Freesia Plants

Apart from their ability to produce oxygen, freesia plants have several other environmental benefits. For instance:

Air Purification

Freesia plants have been found to be effective in removing harmful pollutants from the air, such as formaldehyde and benzene. These pollutants are commonly found in indoor environments and can cause respiratory problems when inhaled over an extended period.

Soil Erosion Prevention

Freesia plants have long roots that help to hold soil together and prevent erosion. This is particularly important in areas that are prone to soil erosion, such as hillsides and riverbanks.

Habitat for Wildlife

Freesia plants provide shelter and food for various wildlife species, such as bees, butterflies, and birds. This is because they produce nectar-rich flowers that attract these animals.

Frequently Asked Questions (FAQ)

Q. Can freesia plants be grown indoors?

A. Yes, freesia plants can be grown indoors as long as they receive adequate sunlight and water. However, they may not produce as much oxygen when grown indoors compared to when grown outdoors.

Q. How often should I water my freesia plant?

A. Freesia plants require moderate watering. Water them once a week or when the soil feels dry to the touch.

Q. Do freesia plants require fertilizer?

A. Yes, freesia plants require fertilizer to grow healthy and produce vibrant flowers. Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium.

Q. Can freesia plants survive in cold temperatures?

A. Freesia plants are sensitive to cold temperatures and cannot survive in frosty conditions. It is best to grow them in warm climates or indoors during the winter months.


Freesia plants are not only beautiful but also have significant environmental benefits. They produce oxygen, purify the air, prevent soil erosion, and provide habitat for wildlife. By growing freesia plants, you can contribute to a healthier environment while enjoying their stunning flowers.
