Monstera vs Split-Leaf Philodendron — Untangling the Confusion
Why "split-leaf philodendron" usually means a monstera, how the true tree philodendron is genuinely different, and the one-look test — holes vs edge splits — that settles it.
Quick answer: "Split-leaf philodendron" is most often a wrong nickname for the Monstera deliciosa — which is not a philodendron at all. There is also a real, separate plant called the split-leaf or tree philodendron (Philodendron bipinnatifidum). To tell them apart: a monstera leaf has enclosed holes within it; a true tree philodendron leaf has deep lobes cut to the edge but no holes. A monstera climbs and wants a moss pole; a tree philodendron sits as a wide, self-supporting rosette. Both are aroids and both are toxic to pets.
Of all the houseplant naming muddles, "monstera vs split-leaf philodendron" is the messiest — because the two names are often used for the same plant. This guide untangles it, then compares the genuinely different plants behind the names.
First, the Naming Confusion
"Split-leaf philodendron" is a name applied to two different things, which is the whole problem:
Usually: a mislabelled monstera
Most plants sold as "split-leaf philodendron" are actually Monstera deliciosa — the famous Swiss cheese plant. It was nicknamed a split-leaf philodendron decades ago, the wrong name stuck, and shops still print it on tags today. The monstera is not a philodendron; it belongs to a separate genus.
Sometimes: the true tree philodendron
There is a genuine plant correctly called the split-leaf or tree philodendron — Philodendron bipinnatifidum (recently reclassified as Thaumatophyllum bipinnatifidum, and long sold as Philodendron selloum). It is a real philodendron, and a different plant from the monstera.
So when someone asks "monstera vs split-leaf philodendron," the honest answer is often "those might be the same plant" — but not always. The rest of this guide treats them as the two distinct plants they can be: the Monstera deliciosa and the true tree philodendron.
Monstera vs Tree Philodendron — Side by Side
| Feature | Monstera deliciosa | Tree (Split-Leaf) Philodendron |
|---|---|---|
| Botanical name | Monstera deliciosa | Philodendron bipinnatifidum |
| Leaf cuts | Enclosed holes (fenestrations) plus edge splits | Deep lobes cut to the edge; no enclosed holes |
| Leaf shape | Broad, rounded, heart-shaped overall | Longer, frillier, deeply dissected and lacy |
| Growth habit | Climbing vine — wants a moss pole | Self-heading — a wide ground-level rosette |
| Grows mostly | Upward | Outward — can exceed 1.5 m wide |
| Space it needs | Vertical height + a support to climb | Open floor space all around |
| Light | Bright indirect | Bright indirect |
| Water | When top 3–5 cm dry | When top 3–5 cm dry |
| Pet safety | Toxic to cats & dogs (calcium oxalates) | Toxic to cats & dogs (calcium oxalates) |
The Reliable Tells
1. Holes vs edge splits — the one that settles it
Look at a mature leaf. A Monstera deliciosa develops actual enclosed holes — fenestrations — surrounded by leaf tissue on all sides, as well as splits running in from the edge. A true tree philodendron never makes enclosed holes; its leaf is cut into deep finger-like lobes that all reach the edge, giving a frilly, lacy outline. Holes within the leaf = monstera. Edge lobes only, no holes = tree philodendron.
2. Climbing vs self-heading
A monstera is a climbing vine. It produces long stems and fat aerial roots, and it wants to grow up a moss pole or tree. A tree philodendron is self-heading: it grows as a wide rosette of leaves radiating from a central point at ground level, eventually developing a stubby woody base. It does not climb and has no interest in a pole.
3. Up vs out
Over time a monstera gets tall, climbing its support, taking up vertical space in a corner. A tree philodendron gets wide — a mature plant easily spreads more than a metre and a half across, dominating floor space rather than height. If you are choosing between them, this is the practical question: do you have height to fill, or width?
4. Leaf outline
A monstera leaf is broad and rounded — a big heart shape, even with all its holes. A tree philodendron leaf is longer and narrower in proportion, more deeply and finely dissected, with a distinctly frilly, almost feathery silhouette.
How Their Care Compares
The basic routine is similar — both are aroids that want bright indirect light, watering when the top 3–5 cm of soil dries, a well-draining mix, and protection from cold winter window glass. The differences that matter are about space and support:
- Support: a monstera needs a moss pole or trellis — and it needs it to fenestrate properly. A tree philodendron needs no support at all.
- Footprint: plan vertical space for a monstera and a wide, clear floor area for a tree philodendron — the latter is often underestimated and outgrows its spot.
- Fenestration: a young monstera makes solid leaves; holes appear with maturity, bright light and a pole to climb. A tree philodendron produces its lobed leaves young, no climbing required.
- Shared risks: overwatering and root rot are the main killer of both, and both are toxic to cats and dogs.

Which Should You Choose?
Choose the monstera if…
You want the iconic holey leaves, you have vertical space and are happy to add a moss pole, and you like a plant you can train and shape as it climbs. The monstera is also the easier of the two to find and to propagate from node cuttings.
Choose the tree philodendron if…
You have open floor space for a big, spreading plant, you want a self-supporting specimen with no pole to manage, and you like the frilly, lacy, deeply lobed leaf. It makes a bold floor statement in a room with width to spare.
Frequently Asked Questions
My plant is tagged "split-leaf philodendron" — what do I actually have?
Check the leaves. If they have enclosed holes within the leaf and the plant is a climbing vine, you have a Monstera deliciosa that was sold under the wrong name — which is very common. If the leaves are cut into deep lobes only at the edges with no holes, and the plant grows as a wide self-supporting rosette, you have a true tree philodendron. Either way, the care is broadly similar; the label matters less than the plant.
Is the Swiss cheese plant a monstera or a philodendron?
"Swiss cheese plant" is a nickname for the Monstera deliciosa (and sometimes the smaller Monstera adansonii) — named for the holes in the leaves. It is a monstera, not a philodendron, even though it is also sold as "split-leaf philodendron." All three names — monstera, Swiss cheese plant, split-leaf philodendron — routinely point at the same Monstera deliciosa.
Is the tree philodendron a Philodendron selloum?
Yes — "Philodendron selloum" is an older name for the same plant now called Philodendron bipinnatifidum, and more recently reclassified by botanists into the genus Thaumatophyllum (as Thaumatophyllum bipinnatifidum). Selloum, hope philodendron, lacy tree philodendron and horsehead philodendron are all common names for this one self-heading species. The naming has changed over the years, but it is a single plant.
Are monstera and philodendron related?
They are relatives in the broad sense: both belong to the aroid family, Araceae, alongside pothos, peace lily and anthurium. But Monstera and Philodendron are separate genera — a monstera is not a kind of philodendron. The family resemblance (heart-shaped or lobed leaves, aerial roots, similar care) is exactly why the names have been muddled for so long.
