Monstera adansonii
Monstera adansonii · the Swiss Cheese Vine
It climbs and trails through the rainforests of Central and South America and the Caribbean, a vine gripping tree trunks with aerial roots. Its enclosed oval holes let light and rainforest downpours pass through the leaf.

Where it's from
Central and South America and the Caribbean
Vines to 4 m
A hemiepiphyte climbing tree trunks near river valleys, far longer than any houseplant.
Wide native range
From Mexico south through Central and South America and across the Caribbean islands.
Outdoors: zones 10–12
Frost-free tropics only. A houseplant everywhere colder.
It is never obliqua
Almost every "Monstera obliqua" for sale is really this plant. True obliqua has leaves so thin they are nearly all hole and barely any leaf, and it grows painfully slowly. Adansonii is fast, cheap and thicker-leaved, with more solid tissue between the holes. The collector saying is simple: it's never obliqua.
Mostly leaf, not hole
Adansonii's enclosed ovals leave solid tissue between them. Obliqua is the opposite.
Fast, not slow
Quick growth is a key tell against the very slow true obliqua.
Cheap is the red flag
Anything cheap sold as obliqua is almost certainly this plant.
How to keep it
LightBright, indirect
Enough light is what drives the holes. Avoid harsh direct sun, which scorches the leaves.
WaterWhen top 1–2 in dry
Keep just moist, never soggy. Root rot is the main killer. Reduce in winter.
Humidity50%+A rainforest plant. Tolerates average rooms with some leaf-edge browning.
Temperature18–27°CWarm rooms. Protect from cold drafts and sudden chills.
SoilChunky aroid mixCoir or peat with perlite and bark. It must drain fast.
FeedingGrowing season onlyA balanced feed through spring and summer.
DifficultyEasyBeginner-friendly and fast in its plain green form.
With petsToxicInsoluble calcium oxalate crystals. Drooling, oral burning and vomiting if chewed.
PropagationCutting at a nodeA stem cutting with at least one node roots in water or moist mix in a few weeks. One of the easiest aroids to multiply.
RepottingEvery 1–2 yearsWhen it becomes rootbound. Give it a pole to climb.
What the data says
What it costs
A plain green vine is a commodity. A variegated one is a status symbol; the white is an unstable mutation collectors chase.

Hover the points. The white in a variegated leaf has less chlorophyll, so it grows slower, weaker and rarer.
IUCN · Not assessed
In the wild
On millions of shelves as an easy commodity, while its rainforest home is cleared.
Monstera adansonii has not been assessed at species level, and its wide range suggests no broad extinction risk. But that masks local pressure: Neotropical rainforest is cleared for cattle and agriculture across its range, and rare variegated forms draw collection pressure. Abundance in cultivation, quiet loss in the wild.
