The Snake Plant (Dracaena trifasciata, previously Sansevieria trifasciata) is a common and popular houseplant prized for its upright, architectural foliage and hardiness. Often called Mother-in-Law’s Tongue, this resilient evergreen perennial is found in homes and offices worldwide. Its global presence has led to a split in folklore, creating a paradox where the plant is simultaneously viewed as a harbinger of good fortune and a symbol of negativity. This cultural disagreement prompts the central question: does the Snake Plant bring good luck or bad luck to a home?
Examining Negative Folklore and Superstitions
Beliefs that associate the Snake Plant with negative energy often stem from its sharp, sword-like leaves. In some cultural contexts, these leaves are interpreted as symbols of aggression or conflict. This interpretation links the plant’s pointed appearance to a “cutting” energy that can potentially slice through harmony or positive flow in a space. The shape is sometimes seen as too harsh for a peaceful indoor environment, leading to the belief that it attracts arguments or bitterness.
The idea that the plant brings bad luck is also occasionally tied to general superstition surrounding negative energies. This folklore suggests that placing the plant in a central area of a room, where its perceived aggressive energy is amplified, can cause disruption. These negative views are often vague and less structured than specific placement philosophies found elsewhere. The primary source of the negative association remains the physical characteristic of the leaves.
The Snake Plant as a Symbol of Good Fortune
In contrast to the negative folklore, the Snake Plant is widely revered in several Eastern philosophical systems, where it is considered a symbol of positive energy and protection. Systems like Feng Shui and Vastu Shastra recognize the plant’s strong, upright growth as an attribute of resilience, strength, and perseverance. Its sharp leaves are not seen as a threat, but rather as a defensive tool capable of cutting through and warding off negative chi or evil spirits.
Placement according to these philosophies is crucial to maximize the plant’s auspicious potential. In Vastu Shastra, placing the plant in the South, East, or Southeast corners of a room is believed to enhance wealth, success, and prosperity. Positioning a Snake Plant near an entrance is also recommended to create a protective barrier, ensuring that only positive energy flows into the home. Traditional guidance advises against placing it in the Northeast corner, as this can disrupt the natural flow of energy. The plant’s ability to thrive under challenging conditions reinforces its symbolism as a source of vitality and determination.
Scientific Benefits and Toxicity Concerns
Separating fact from folklore, the Snake Plant provides demonstrable biological benefits that account for its popularity. Its inclusion in the NASA Clean Air Study highlighted its ability to actively remove airborne toxins from indoor spaces. The plant is effective at absorbing volatile organic compounds (VOCs) such as formaldehyde, benzene, trichloroethylene, and xylene. These compounds are commonly released by household materials like paints, cleaners, and furniture.
The Snake Plant possesses a unique photosynthetic process called Crassulacean Acid Metabolism (CAM). This process allows it to open its stomata and release oxygen primarily at night. This makes it a popular choice for bedrooms, as it works to purify the air while residents sleep. While the plant does release oxygen, claims that a few plants can sustain human life in a sealed room are scientifically unfounded.
Toxicity Concerns
Despite its air-purifying qualities, a practical consideration is the plant’s mild toxicity if ingested. The leaves contain organic compounds called saponins, which are present throughout the plant’s structure. If pets or small children chew on or swallow pieces of the foliage, the saponins can cause symptoms. These symptoms include nausea, vomiting, or swelling and numbness of the mouth and throat. While the reaction is typically mild and not life-threatening, owners should exercise caution by placing the Snake Plant out of reach of curious animals and children.
