In short
- Extremely tough — tolerates neglect, shade and drought.
- The most common mistake is overwatering — water very sparingly.
- Grows in almost any light level, from full sun to shade.
- Purifies indoor air, cited in NASA studies.
- Toxic to dogs and cats if chewed.

Characteristics
A succulent with stiff, upright, sword-shaped leaves growing from an underground rhizome, often with yellow margins and lighter, cross-banded mottling. Grows slowly, forming dense clumps.
Growing and care
Watering
The fleshy leaves store water — the most common cause of death is overwatering. Water only after the substrate has dried out completely.
Fertilizing
Very undemanding — too much fertilizer does more harm than too little.
Planting
Free-draining cactus/succulent substrate; a pot with a drainage hole is essential.
Pruning
Remove damaged leaves by cutting them off right at the base.
Companion plants
Good companions
Identical requirements — very infrequent watering, shade tolerance; a great pairing for forgetful plant owners.
Bad companions
Require constant moisture, which causes root rot in the snake plant.
The evidence level indicates whether the relationship is backed by research, observation, or gardening tradition.
Diseases and pests
Insects covered in a white, cottony, waxy coating, gathering in leaf axils, at the base of shoots and on the underside of leaf blades. They look like tufts of cotton wool. They suck sap, weaken the plant and excrete sticky honeydew, on which black sooty mould develops. A common pest of houseplants and succulents.
Spider mitesTiny (0.3–0.5 mm) arachnids, hard to spot with the naked eye, feeding on the underside of leaves. Symptoms: fine, pale speckling (feeding punctures); over time the leaves turn grey, yellow and dry out. Under heavy infestation a fine webbing becomes visible. Warm, dry air favours their development — a common problem for houseplants in winter near radiators.
Toxicity

|---|---|---|
| Humans | Mild | Contains saponins that irritate the digestive tract if ingested. |

History and origin
The plant has been a staple of homes and offices worldwide for decades thanks to its exceptional toughness. It earned the nickname "mother-in-law's tongue" from the shape and stiffness of its leaves.
Uses
For living rooms and offices with any light level, including bedrooms, thanks to its nighttime oxygen release. Ideal for beginners or people who travel often.
Trivia
- The snake plant is one of the few houseplants that carries out nighttime gas exchange (CAM metabolism) and releases oxygen at night.
- In 2017 botanists reclassified the species from the genus Sansevieria to Dracaena based on genetic research.
Frequently asked questions
Why do a snake plant's leaves go soft and topple over?
This is a classic symptom of overwatering and root rot. Cut back on watering, check the drainage, and if needed repot the plant into fresh, dry substrate, removing any rotten roots.
How often should you water a snake plant?
Very rarely — about every 2 weeks in summer and once a month in winter, always after the substrate has dried out completely. It's one of the few plants easier to kill with too much water than too little.
Will a snake plant grow in a dark room?
Yes, it tolerates shade, though it grows faster and keeps more intense coloring in a bright spot. It's one of the most light-flexible plants around.
