What is the Snake Plant? A Brief Overview
Before diving into the oxygen-producing properties of the snake plant, it’s helpful to know a little more about it.
The snake plant, scientifically known as Sansevieria trifasciata, is a succulent native to West Africa. Its stiff, sword-like leaves, which can grow upright to impressive heights, give it an elegant yet rugged appearance.
These striking leaves often feature dark green hues with lighter bands or yellow edges, depending on the variety.
Some popular types of snake plants include:
- Sansevieria trifasciata ‘Laurentii’ – Characterized by its tall, variegated leaves with yellow borders.
- Sansevieria cylindrica – Known for its cylindrical leaves that grow in a fan shape.
- Sansevieria hahnii – A dwarf version with a rosette-like growth pattern.
This resilient plant thrives with minimal care, tolerating low light and irregular watering—making it ideal for busy people or beginners.
But beyond its aesthetic appeal and hardy nature, the snake plant offers a hidden superpower: the ability to purify air and, allegedly, produce oxygen even at night.
Photosynthesis and Oxygen Production: The Basics
To understand whether the snake plant produces oxygen 24 hours a day, we need to revisit some basic science: photosynthesis.
How Plants Normally Produce Oxygen
During photosynthesis, most plants use light to convert carbon dioxide (CO₂) and water (H₂O) into glucose and oxygen (O₂). This process generally takes place in two main stages:
- Light-Dependent Reaction: Occurs during the day when sunlight is available.
- Calvin Cycle (Light-Independent Reaction): Follows the light-dependent reaction, allowing the plant to produce glucose.
In a typical plant, oxygen is produced during the day and released into the environment.
At night, in the absence of light, plants switch to respiration, where they consume oxygen and release carbon dioxide—essentially the opposite of photosynthesis.
What Makes the Snake Plant Different?
The snake plant, along with a few other succulents and cacti, belongs to a group of plants that perform Crassulacean Acid Metabolism (CAM) photosynthesis. This adaptation allows the snake plant to:
- Open its stomata (pores) at night to take in carbon dioxide (CO₂).
- Store the CO₂ as an organic acid.
- Close its stomata during the day to prevent water loss and use the stored CO₂ to perform photosynthesis and produce oxygen.
This clever adaptation allows the snake plant to survive in arid environments where water conservation is crucial. But it also means that, unlike most plants, the snake plant can produce oxygen at night.

Does the Snake Plant Produce Oxygen 24 Hours a Day?
The Scientific Answer
The short answer is: No, the snake plant does not produce oxygen 24 hours a day. However, it does produce oxygen at night, which is unusual for most houseplants.
Here’s a more nuanced breakdown:
- During the day: The snake plant performs regular CAM photosynthesis, using stored carbon dioxide to produce oxygen.
- At night: The snake plant continues to intake carbon dioxide and prepares for the next day’s photosynthesis while also releasing some oxygen.
This makes the snake plant exceptional in the sense that it releases oxygen when most other plants are absorbing it.
Why Doesn’t It Produce Oxygen 24/7?
No plant can photosynthesize continuously without interruption. Photosynthesis requires light energy, so even CAM plants like the snake plant can’t produce oxygen non-stop.
However, their ability to continue releasing oxygen during the night gives the impression of round-the-clock oxygen production.
