Snake plant is the houseplant you can leave alone for a month and come back to find unchanged. It tolerates drought, low light, dry air, heat, and heavy shade per NC State Extension. The one thing it doesn't tolerate is overwatering. Also worth knowing — it's not a Sansevieria anymore.

What it is
The accepted scientific name is Dracaena trifasciata (Prain) Mabb. per Kew POWO. In 2017, David Mabberley's Plant-book moved the snake plant out of the genus Sansevieria and into Dracaena — based on molecular phylogenetic work showing snake plants are nested within Dracaena, not separate from it.
Sansevieria trifasciata is now a homotypic synonym. The common name and all cultivars (Laurentii, Hahnii, Moonshine, Black Coral) stay the same. The genus changed; the plant did not.
Family is Asparagaceae. Native range per Kew POWO is southern Nigeria to west-central tropical Africa and Tanzania, growing as a rhizomatous geophyte in the seasonally dry tropical biome.
Light
Low to bright indirect light. NC State lists it as one of the most light-tolerant common houseplants — it'll survive in deep shade and grow faster in bright indirect. MBG recommends warm, bright locations but explicitly says it tolerates shade. Protect from hot afternoon direct sun, which can scorch leaves.
This is genuinely one of the few houseplants that survives in a windowless office bathroom under fluorescent light.
Watering
This is the only part of snake plant care that matters. NC State is direct: "Well-drained soil and careful watering are a must; do not overwater, as the roots will rot." Spring through autumn, let the soil dry between waterings. In winter, water only every one to two months.
MBG adds an important detail: do not pour water into the center of the rosette where the leaves meet. Water the soil, not the plant.
If you've killed a snake plant before, it was almost certainly overwatering. The rhizome — a thick underground stem the plant grows from — rots fast in saturated soil.
Humidity
Low humidity is fine. NC State explicitly lists humidity as something the snake plant resists rather than requires. No humidifier, no pebble tray, no misting. This is one of the few houseplants where dry winter indoor air is genuinely not a problem.
Soil and pH
Well-drained potting mix is essential. A cactus or succulent mix amended with extra perlite works better than standard potting soil — the snake plant's natural habitat is seasonally dry, and its roots aren't built for sustained moisture.
NC State lists tolerance for neutral (6.0–8.0) and alkaline (>8.0) soils — an unusually wide pH range for a common houseplant. You don't need to worry about adjusting pH for this one.
Temperature
NC State notes tolerance down to around 50°F, with USDA Hardiness Zones 10a–12b outdoors. Average indoor temperatures are well within the comfort range. Avoid sustained exposure below 50°F.
Pet safety
Toxic to dogs and toxic to cats per the ASPCA's Dracaena entry. Toxic principle is saponins. Symptoms include vomiting (occasionally with blood), drooling, depression, diarrhea, and dilated pupils in cats.
NC State classifies the toxicity as low severity — the saponins cause GI distress but aren't acutely dangerous in the way true lilies or sago palm are. Still worth keeping out of reach of pets that chew.
The "impossible to kill" framing — accurate but with one caveat
NC State lists the snake plant's resistances explicitly: drought, dry soil, heat, heavy shade, low humidity. That covers most of the things that kill houseplants. The plant survives genuine neglect — months without water, dim rooms, dry winter air, hot summer windowsills.
The caveat: it dies fast from overwatering. Root rot happens in days, not weeks, once the rhizome gets saturated. The accurate framing is: nearly impossible to kill from neglect, readily killed by overcare.
Common problems
| Symptom | Likely cause | Fix |
|---|---|---|
| Mushy base, leaves falling over | Root rot from overwatering per NC State | Unpot, inspect rhizome, cut away mushy sections with clean knife, let healthy sections callus 24 hrs, repot in dry cactus mix; barely water for a month |
| Leaves curling or wrinkling | Chronic underwatering (it can happen, just very slowly) | Water thoroughly; resume normal schedule |
| Brown crispy tips | Inconsistent watering or salt buildup from fertilizer | Flush pot with extra water; halve fertilizer |
| Pale, washed-out coloring | Direct hot afternoon sun bleaching the leaves | Move further from window |
| Mealybugs or spider mites | Standard indoor pests per MBG | Wipe leaves; insecticidal soap or neem |
Propagation
Two reliable methods. Division is the easiest — when you repot a mature snake plant, gently pull apart the rhizome into clumps, each with 2–3 leaves and some roots. Pot each clump separately.
Leaf cuttings also work but they take months. Cut a healthy leaf into 2–3 inch segments, let the cut ends callus over for 1–2 days, then push the bottom edge into moist potting mix. Roots emerge in 4–8 weeks. Note that variegated cultivars (like Laurentii) often lose their variegation when propagated from leaf cuttings — they revert to solid green. Division preserves the variegation; leaf cuttings often don't.
