Monstera adansonii

The Monstera adansonii, nicknamed “Swiss cheese vine” or “monkey mask”, is the climbing little sister of the famous deliciosa. Its thin leaves are riddled with oval holes — fenestrations that never reach the leaf edge — making it a striking vine whether hanging or on a pole. It’s one of the most beginner-friendly Monsteras.

What you really need to know

The adansonii is easy as long as you watch humidity and watering. In a small pot or hanging basket, the substrate dries fast: check the top every 4-5 days. Bright indirect light, good humidity and a moss pole are all it needs for fast growth and well-fenestrated leaves.

Light

Bright indirect light. Near an east- or west-facing window, or 1-2 m from a sheer-curtained south window. In shade, leaves stay small and lose their holes; in direct sun they scorch. Rotate the plant a quarter turn weekly for an even shape.

Watering

Water as soon as the top 2-3 cm dry out: on average every 5 days in summer, every 9 days in winter. The thin leaves tolerate prolonged drought poorly (dry, crispy edges) but equally hate excess water. Water deeply, let it drain, and never leave it sitting in water.

Humidity and temperature

Ideal between 60-80 % humidity and 18-27 °C. This is a tropical understory plant: below 50 % humidity, leaf edges brown. Group your plants or add a humidifier in winter.

Mistakes to avoid

Letting the substrate dry out completely — crispy edges and leaf drop
Overwatering in a hanging basket where drainage is slow — root rot
Air that’s too dry near a radiator — browned leaf edges
No support — spindly stems and reduced fenestration

Toxicity

⚠️ Toxic to cats, dogs and children: like all aroids, it contains calcium oxalate crystals that irritate when ingested. Keep it up high, out of reach.

Propagation

Very easy: cut just below a node (ideally with an aerial root) and place the cutting in water. Change the water every 5 days and pot up when roots reach 5-8 cm. See our complete water propagation guide.

Varieties and common confusions

Monstera obliqua: even thinner leaves, up to 90 % holes — often confused but far rarer and harder. See our Monstera obliqua sheet.
“Wide” vs “narrow” forms: depending on leaf width.

Why are its leaves turning yellow?

Yellow leaves on Monstera adansonii most often come from overwatering, low light or recent stress. First check substrate moisture, root condition and placement.

Where should I place it at home?

Monstera adansonii prefers bright indirect light. Place it near a bright window without harsh direct sun, then adjust if leaves fade, brown or growth slows.

Is it beginner-friendly?
