Monstera vs Philodendron: 5 Ways to Tell Them Apart

The split-leaf philodendron and the Swiss cheese plant (Monstera deliciosa) look so similar that Home Depot, IKEA, and most online plant shops routinely mislabel them. They're not even in the same genus — but they grow in the same jungle, have the same fenestrated leaves, and end up on the same shelf. Here are the five quick visual tests that always work, plus what the difference means for how you care for the plant.

Quick verdict

Easiest test: look at the holes in the leaves. Monstera holes are inside the leaf — clean ovals or slits that don't reach the edge. Philodendron splits run from the leaf edge inward.
Second test: new monstera leaves emerge from a papery sheath that dries up and falls off. New philodendron leaves emerge from a stipule that stays attached and stays green.
Care difference: very similar. Both want bright indirect light, weekly-ish watering, moss pole support. Monsteras dry out faster and want a touch more light.

The three confusion pairs people actually search for

Before we get to the five tests, it helps to know which plant you're comparing. "Monstera vs philodendron" is really three different lookups people confuse:

You probably mean…	If you have a plant with…
Monstera deliciosa vs Split-leaf philodendron (Philodendron bipinnatifidum, formerly P. selloum)	Large heart-shaped leaves with deep splits, growing tall on a moss pole — this is the classic pairing, and 90% of confusion is here
Monstera adansonii vs Heart-leaf philodendron (Philodendron hederaceum)	Small heart-shaped leaves, vining or trailing from a pot — Monstera adansonii has obvious holes; heart-leaf philodendron is smooth
Mini Monstera (Rhaphidophora tetrasperma) vs Monstera deliciosa juvenile	Small split leaves, vining — neither is technically a "monstera"; the mini monstera is its own genus. Tests below still work

The five tests below all work on the first pair, which is the one people actually mean. Notes on the other two are at the end.

The 5 ways to tell them apart

#1Look at the holes

Monstera Has fenestrations — clean oval holes or elongated slits in the middle of the leaf, completely surrounded by leaf tissue. Edges of the leaf stay mostly intact.

Philodendron (split-leaf) Has splits, not holes. The leaf is deeply divided into lobes that radiate from the central vein out to the edge. No interior holes.

This is the single most reliable test. Walk up to the plant, find a mature leaf, and trace one of the openings with your finger. If it forms a closed shape inside the leaf, it's a monstera. If it opens out to the edge, it's a philodendron.

Caveat: very young monstera leaves may not have fenestrations yet — they look like solid heart shapes until the plant is mature enough to develop holes (usually after 2–3 years).

#2Watch how new leaves emerge

Monstera New leaves come out of a cataphyll — a stiff, papery, light-green protective sheath that turns brown, dries up, and falls off (or peels off) after the leaf has unfurled.

Philodendron New leaves come out of a stipule — a softer, leafy green sheath that stays attached to the plant after the leaf unfurls. Often stays green for months.

If you see paper-bag-brown husks lying around the base of the plant, that's a monstera. If the joints between leaves and stem still have soft green leafy bits attached weeks after a new leaf opened, that's a philodendron.

#3Check the petiole (leaf stem)

Monstera Petiole is round, smooth, and stiff. Where it joins the main stem, there's a clear sheath wrapping the base. Often has small raised bumps called "geniculum" — a hinge-like swelling near the leaf.

Philodendron Petiole is round but often has a noticeable groove running its length, especially on split-leaf philodendrons. No geniculum hinge.

Pinch the petiole between your fingers and roll it. Monstera petioles feel like a uniform tube. Many philodendron petioles have a channel you can feel.

#4Look at the aerial roots

Monstera Thick, woody-looking brown aerial roots — typically one or two per node, can grow several feet long if unmanaged. They're how the plant climbs trees in the wild.

Philodendron Thinner, often greenish aerial roots — usually more numerous per node but smaller. Stay closer to the main stem.

Mature monstera roots can be as thick as a pencil. Mature philodendron roots usually stay finger-nail thin. This test is especially useful for plants that don't have many splits/holes yet — the roots are a tell even on juveniles.

#5Check growth habit

Monstera deliciosa Climber. Wants to attach itself to something tall (in the wild, a tree; at home, a moss pole). Without support, it sprawls sideways and leaves stay smaller.

Split-leaf philodendron Self-heading. Grows up from a central trunk that thickens over time. Doesn't need a moss pole — it stands on its own and can spread 6+ feet across the floor at maturity.

If the plant is on a moss pole and the leaves keep getting bigger as it climbs, it's a monstera. If the plant stands up by itself in the middle of a pot and the leaves radiate outward like a hand, it's a split-leaf philodendron.

Care: are they different?

Mostly the same, with three small differences worth knowing:

	Monstera deliciosa	Split-leaf Philodendron
Light	Bright indirect; tolerates a few hours of morning sun	Bright to medium indirect; more tolerant of low light
Watering	Top 2" of soil dry — usually every 7–10 days	Top 2" of soil dry — usually every 10–14 days (holds water longer)
Humidity	50%+ ideal, tolerates lower	40%+ ideal, more forgiving
Support	Needs a moss pole for mature leaves	Self-supporting, no pole needed
Mature size indoors	6–10 ft tall on a pole	4–6 ft tall, 6 ft wide
Pet-safe?	No — toxic to cats and dogs (calcium oxalate crystals)	No — toxic to cats and dogs (same compound)

For pet-safety details and what symptoms to watch for, see our guide on toxic plants for dogs and cats. Both of these plants are on that list.

What about the other confusion pairs?

Monstera adansonii vs Heart-leaf philodendron

This one's actually easier than the first pair. Monstera adansonii has obvious holes in every mature leaf — that's why it's also called Swiss cheese vine. Heart-leaf philodendron has smooth, solid heart-shaped leaves with no fenestrations at any age. If you see holes, it's a monstera; if not, it's a philodendron.

Mini Monstera (Rhaphidophora tetrasperma) vs juvenile Monstera deliciosa

Despite the nickname, mini monstera isn't a monstera at all — it's a separate genus that just happens to look like a small Monstera deliciosa. The split pattern in mini monstera leaves is more aggressive and reaches the leaf edge (more like a philodendron split), while juvenile monstera leaves typically start with holes that don't extend to the edge. Mini monsteras also grow much faster and stay smaller overall.

How to confirm with a photo

If you're standing in front of a plant at a nursery — or you bought one labeled "philodendron" and you suspect it's actually a monstera — snap a photo with Nature Lenz and we'll identify the species in seconds. We can usually distinguish Monstera deliciosa from Philodendron bipinnatifidum from a single leaf photo, even at the juvenile stage where the fenestration test fails.

The most useful angles for a photo ID:

A mature leaf photographed flat (face-on, not at an angle) — this gives the AI the best look at hole vs split patterns
A photo showing the petiole connection to the main stem — for the geniculum / sheath test
A photo of any visible aerial roots — these are species-specific

FAQs

Why does this matter? Aren't they basically the same plant?

For day-to-day care, they're similar enough that you can keep one alive without knowing which it is. But it matters when you're: (1) buying a plant — split-leaf philodendrons are usually cheaper than monsteras of the same size, and unscrupulous sellers mislabel; (2) propagating — the techniques are slightly different (monsteras root from node cuttings; philodendrons root from stem cuttings); (3) repotting — monsteras need taller, narrower pots to accommodate the climbing root system, while philodendrons want wider, shallower pots.

Is split-leaf philodendron the same as philodendron selloum?

Yes — Philodendron selloum was reclassified as Philodendron bipinnatifidum, which is what botanists now call it. Some nursery tags still say "selloum" out of habit. It's the same plant.

Is the Swiss cheese plant a monstera or a philodendron?

The Swiss cheese plant is Monstera deliciosa. Some retailers also call Monstera adansonii a "Swiss cheese vine" — both are monsteras, neither is a philodendron, despite the common confusion.

My nursery tag says "Philodendron Monstera" — what is that?

That's a made-up tag. There's no plant called "Philodendron Monstera" because the two are different genera. Most often this tag is attached to a Monstera deliciosa that the nursery's supplier mislabeled. Use the five tests above to figure out which you actually bought.

Which is easier to care for — monstera or philodendron?

Split-leaf philodendron, slightly. It tolerates lower light, holds water longer between waterings, and doesn't need a moss pole. Monstera deliciosa is still easy by houseplant standards but it has more requirements to look its best (light, support, humidity).

Are either of these poisonous?

Both are mildly toxic to humans (skin irritation from sap, mouth burning if chewed) and significantly more toxic to cats and dogs due to calcium oxalate crystals. Keep both away from pets. See our toxic plants guide for symptoms and what to do if your pet chews on either.
