What is a Snake Plant?
The snake plant (Sansevieria trifasciata) is a species of flowering plant that belongs to the family Asparagaceae. Its long, upright leaves are green with varying patterns of horizontal stripes, giving it the appearance of a snake’s skin, which is how it earned its common name.
Snake plants are typically native to tropical regions of West Africa, specifically Nigeria and the Congo. However, they have since spread in popularity across the world. The plant is known for being extremely hardy, able to withstand neglect, and thriving in conditions that would challenge most other houseplants.
Key Features of the Snake Plant:
- Height: The leaves of a snake plant can grow up to several feet tall, with some varieties reaching heights of up to 6 feet.
- Leaves: Thick, sword-like leaves that stand upright, often with a slightly variegated pattern or margins of yellow or white.
- Growth Habit: Snake plants grow in clusters, with new leaves emerging from underground rhizomes.
- Lifespan: With proper care, a snake plant can live for several decades.
- Air Purification: The snake plant is known for its ability to remove toxins such as formaldehyde, benzene, and xylene from the air, making it an excellent plant for improving indoor air quality.
Though generally classified as succulents, snake plants possess some unique traits that set them apart from the more typical succulent varieties, including their ability to tolerate low light and their high oxygen output during the night, which contrasts with many other plants that release carbon dioxide at night.
History and Origin of the Snake Plant
The snake plant has a long and storied history, dating back thousands of years. Its origins can be traced to tropical West Africa, where it was first discovered. Indigenous tribes used the plant for its various medicinal properties, including wound healing, antibacterial, and antifungal uses. The leaves were sometimes used to treat ailments like headaches, digestive problems, and inflammation.
As European botanists and explorers traveled to Africa, the plant made its way to Europe and later to other parts of the world, where it became increasingly popular as both an ornamental and practical plant. Its unique appearance and ability to thrive in harsh conditions made it a prized possession among early plant collectors.
Today, the snake plant has become one of the most common houseplants globally, especially in places like North America, Europe, and Asia.
Snake Plant Varieties
There are over 70 recognized species of Sansevieria, but the most common and well-known is Sansevieria trifasciata. However, within this species, there are several popular varieties, each with its own distinct characteristics.
a. Sansevieria trifasciata ‘Laurentii’
This is perhaps the most recognizable type of snake plant, with its tall, sword-shaped leaves edged in yellow and vertical stripes of light and dark green across the center.
b. Sansevieria trifasciata ‘Zeylanica’
This variety has broader, slightly shorter leaves with a more uniform pattern of green and white variegation. It’s often used as a background plant due to its subtler coloration.
c. Sansevieria cylindrica
Unlike other varieties, this snake plant has cylindrical, tube-like leaves that grow upright in a fan-shaped arrangement. This variety is often used as a centerpiece plant due to its unique appearance.
d. Sansevieria ‘Moonshine’
The Moonshine variety stands out due to its light, almost silvery-green leaves, which create a striking contrast when planted alongside other, darker green snake plants.
e. Sansevieria ‘Black Gold’
With dark, almost black leaves edged with a golden-yellow outline, this variety is prized for its dramatic and bold aesthetic.
Each of these varieties offers something slightly different in terms of appearance, but they all share the resilience and low-maintenance characteristics that make snake plants such popular choices.
The Science Behind the Snake Plant’s Air-Purifying Abilities
One of the most well-known benefits of the snake plant is its ability to purify the air. Studies conducted by NASA in the 1980s found that snake plants, along with a handful of other houseplants, can remove toxins from the air and improve indoor air quality.
Snake plants are particularly good at filtering out toxins such as:
- Formaldehyde: Found in household products like cleaning agents, furniture, and some fabrics.
- Benzene: Found in paints, cigarette smoke, and plastics.
- Xylene: Found in solvents used in the leather, rubber, and printing industries.
What sets the snake plant apart from other houseplants is its unique ability to perform photosynthesis at night. While most plants absorb carbon dioxide and release oxygen during the day, snake plants can continue to do this at night, making them especially beneficial for bedrooms.
This process is known as CAM (Crassulacean Acid Metabolism) photosynthesis, where the plant opens its stomata during the cooler night hours to reduce water loss, allowing it to absorb carbon dioxide and produce oxygen. This makes snake plants excellent bedroom plants, as they can help you breathe cleaner air while you sleep.
How to Care for a Snake Plant
One of the reasons why the snake plant is so popular is that it requires very little attention. However, with the right care, you can ensure that your snake plant thrives for years to come.
a. Light Requirements
Snake plants are highly adaptable and can thrive in a wide range of light conditions. Ideally, they prefer bright, indirect light, but they can also tolerate low light or even direct sunlight for short periods.
In lower light conditions, snake plants will grow more slowly, and their leaves may become more prone to drooping. In contrast, brighter light can encourage faster growth and more vibrant coloring in the leaves. However, too much direct sunlight can scorch the leaves, leading to browning at the tips.
b. Watering Schedule
The snake plant is a succulent, meaning it stores water in its leaves and requires less frequent watering than many other houseplants. Overwatering is one of the most common mistakes made with snake plants and can lead to root rot.
A good rule of thumb is to let the soil dry out completely between waterings. Depending on your climate and the time of year, you may only need to water your snake plant once every 2-4 weeks.
During the colder winter months, the plant will go into a state of dormancy, requiring even less water. In the summer, you may need to water more frequently, but always check the soil before adding water.
c. Ideal Soil and Fertilizer
Snake plants prefer well-draining soil, similar to what you’d use for other succulents and cacti. A commercial potting mix designed for succulents, or a blend of potting soil with sand or perlite, will work well.
As for fertilization, snake plants don’t need a lot of feeding. During the growing season (spring and summer), you can fertilize the plant with a balanced, diluted fertilizer every month or so. Avoid fertilizing in the fall and winter when the plant isn’t actively growing.
d. Repotting and Propagation
Snake plants are slow growers and only need repotting every 2-3 years or when they’ve outgrown their container. When repotting, choose a pot that’s just slightly larger than the current one, as snake plants prefer to be a little root-bound.
Propagation is easy and can be done through leaf cuttings or by dividing the plant at the root level. Simply cut a healthy leaf, let it callous over for a day or two, and place it in water or directly in soil. Alternatively, you can divide the plant by removing it from its pot and gently separating the root clumps.
Common Problems and Solutions
Though snake plants are relatively hardy, they are not entirely immune to problems. Here are a few common issues and how to solve them:
a. Pests
Snake plants can occasionally attract pests like mealybugs or spider mites. These pests are small but can cause significant damage if left untreated. Regularly inspect your plant for any small white bugs or fine webbing and treat infestations with insecticidal soap or by wiping down the leaves with a cloth soaked in diluted rubbing alcohol.
b. Diseases
The most common disease that affects snake plants is root rot, which is typically caused by overwatering or poorly draining soil. If you notice your snake plant’s leaves becoming mushy, yellowing, or wilting, it could be suffering from root rot. To fix this, remove the plant from its pot, trim away any rotten roots, and repot it in fresh, well-draining soil.
c. Overwatering and Underwatering
Overwatering is one of the most frequent causes of snake plant problems. As mentioned earlier, it’s essential to let the soil dry out between waterings. If you notice drooping or yellowing leaves, you may be overwatering.
On the other hand, underwatering is less common but still a possibility, especially if the plant’s leaves become shriveled or overly dry. If this happens, increase the frequency of watering, but still avoid waterlogging the plant.
