Plants do a lot apart from providing nourishment and keeping living organisms alive. Some plants also eliminate environmental toxins, while others produce oxygen and keep the outdoor air fresh and clean.

The oxygen plants produce is a result of photosynthesis, and you may find that certain plants release more oxygen than others.

Our detailed guide lists twenty common outdoor plants that produce the most oxygen. 

20 Plants That Produce the Most Oxygen

Some of the trees and plants that generate more oxygen include the following:

1. Maple

The maple tree belongs to the Acer genus of the family Sapindaceae. While there are over 120 maple species, you’ll come across silver maple, sugar maple, bigleaf, boxelder, and red maple in North America as shade trees. 

A maple tree begins to bloom during spring but becomes dormant during the cold season. 

Maple trees produce enough oxygen for two people in a single day. It’s worth noting that although these trees disperse the most oxygen in the environment, they can also be messy. 

2. Douglas Fir

3. True Firs

True firs comprise over 40 evergreen species native to Central America, Europe, Asia, and North Africa. 

Fir trees have needle-like leaves that grow from the branches. Unlike other evergreen trees, true firs are attached to their leaves by something that looks like a suction cup at the base of the needle clump. 

4. Spruce
