Pothos vs Philodendron — How to Tell Them Apart
The two most-confused houseplants, side by side — the reliable tests that tell a pothos from a heartleaf philodendron, the small differences in care, and which is the better pick for a Canadian home.
Quick answer: The fastest way to tell pothos from philodendron is the petiole — the little stem joining leaf to vine. A pothos petiole has a groove cut down it; a philodendron petiole is smooth and round. Pothos leaves are thicker, waxy and slightly textured; heartleaf philodendron leaves are thinner, softer and matte, and emerge with a bronze-pink tint from a papery sheath called a cataphyll. They are different plants from different genera in the same family, their care is nearly identical, and both are toxic to cats and dogs.
Pothos and heartleaf philodendron are the two most-confused houseplants in the world — both are easy-care trailing vines with glossy heart-shaped leaves, both are sold cheaply at every Canadian garden centre and grocery store, and both are often mislabelled. They are not the same plant: pothos is Epipremnum aureum and heartleaf philodendron is Philodendron hederaceum, two separate genera that happen to share a family (Araceae, the aroids) and a similar look.
The good news for a new plant owner: it barely matters which one you have, because their care is nearly identical. But if you want to know for certain — for propagation, for labelling, or just to satisfy curiosity — there are several reliable tells. This guide covers all of them, then compares the two on care and looks.
Pothos vs Philodendron — Side by Side
| Feature | Pothos | Heartleaf Philodendron |
|---|---|---|
| Botanical name | Epipremnum aureum | Philodendron hederaceum |
| Petiole (leaf stem) | Grooved — a channel runs down it | Smooth and round all around |
| Leaf texture | Thicker, waxy, slightly stiff and a little bumpy | Thinner, soft, smooth, matte |
| Leaf shape | Heart-shaped but slightly asymmetric, often a more pointed tip | A more even, true heart shape with a deeper curl |
| New growth | Unfurls directly from the previous leaf; no sheath | Emerges from a cataphyll (sheath); often bronze-pink at first |
| Aerial roots | One thick, stubby root per node | Several thinner roots per node |
| Light | Low to bright indirect; variegation needs more light | Low to bright indirect; a little more low-light tolerant |
| Water | When top 3–5 cm dry; very drought-forgiving | When top 3–5 cm dry; slightly thirstier |
| Cold sensitivity | A little more sensitive — keep off cold glass | Slightly hardier in a cool room |
| Pet safety | Toxic to cats & dogs (calcium oxalates) | Toxic to cats & dogs (calcium oxalates) |
The Reliable Tells — Ranked
1. The petiole — the one test that always works
The petiole is the short stem that joins each leaf to the main vine. Run a fingernail down it. On a pothos the petiole has a distinct groove or channel cut into its top side — you can feel the indentation. On a philodendron the petiole is smooth and round in cross-section, with no groove. This single feature settles the question every time, even on a young plant with no other clues.
2. New growth — cataphyll or no cataphyll
A philodendron produces each new leaf from a cataphyll — a thin, separate protective sheath that wraps the emerging leaf, then dries to a papery brown and falls off (or stays on the vine). A pothos has no cataphylls at all; its new leaf simply unfurls straight out of the previous leaf's base. If you see papery brown sheaths along the vine, it is a philodendron. Heartleaf philodendron new leaves also often emerge with a bronze or pinkish tint that greens up as they mature; pothos new leaves come in green.
3. Leaf feel and thickness
Hold a leaf between finger and thumb. A pothos leaf is noticeably thicker, stiffer and slightly waxy, sometimes with a faint texture or unevenness to the surface. A philodendron leaf is thinner, softer, more flexible and smoother, with a matte rather than glossy-stiff finish. Once you have felt both, it becomes an instant tell.
4. Leaf shape and symmetry
Both have heart-shaped leaves, but a philodendron leaf is a more even, symmetrical heart with a deeper, more pronounced curl where the two lobes meet the stem. A pothos leaf is a little less symmetrical — one side often slightly larger than the other — and tends to taper to a more drawn-out point. This is the least reliable tell on its own, so use it to confirm rather than decide.
5. Aerial roots at the nodes
At each node — the point where a leaf meets the vine — a pothos produces a single thick, stubby aerial root, while a philodendron tends to produce several thinner aerial roots clustered together. You will need a reasonably mature plant to use this one, but it is a good cross-check.
Do They Need Different Care?
Barely. This is the reassuring part: pothos and heartleaf philodendron want the same things, and a routine that suits one suits the other. Both want bright indirect light, watering when the top 3–5 cm of soil dries, a well-draining potting mix, and both root effortlessly from a node cutting in water. The differences are small enough that you do not need to identify your plant to keep it alive:
- Low light: heartleaf philodendron holds its shape and colour a little better in a genuinely dim room; pothos in low light tends to stretch and lose variegation faster.
- Watering: pothos is marginally more drought-forgiving — it shrugs off a missed watering; philodendron prefers slightly more consistent moisture.
- Cold: pothos is a touch more cold-sensitive, so in a Canadian winter keep it the regulation 30–50 cm back from cold window glass.
- Variegation: highly variegated pothos (Marble Queen, Manjula, N'Joy) need bright indirect light to keep their white; this is a pothos-variety issue rather than a pothos-vs-philodendron one.
Both share the same vulnerabilities, too: overwatering and root rot are the number-one killer of each, and both are toxic to cats and dogs. For the full routine, see the dedicated pothos care guide and philodendron care guide.
Which Should You Choose?
Choose pothos if…
You want the most forgiving possible plant, you like the option of bold variegation (golden, marble, neon, N'Joy), and your spot gets at least medium light. Pothos is the better pick for a frequent traveller or a self-described plant-killer — it tolerates neglect best of all.
Choose philodendron if…
Your room is on the dim side, you prefer softer foliage and a faster, more graceful trailing habit, or you like the bronze-pink flush of new leaves. Heartleaf philodendron is the slightly better performer in a low-light Canadian apartment.
Honestly, though: for most people the right answer is "whichever one looks best to you in the shop." The care is close enough that you cannot go wrong, and both are excellent, inexpensive, beginner-proof first plants for a Canadian home.
Frequently Asked Questions
Is a pothos a type of philodendron?
No. Pothos belongs to the genus Epipremnum and philodendron to the genus Philodendron — they are different plants in the same family (Araceae). The confusion has deep roots: golden pothos was historically mislabelled as a philodendron, and the nickname "devil's ivy" gets attached to both. They are relatives in the broad sense, like cousins, not the same plant.
Which grows faster, pothos or philodendron?
In good light they grow at a similar pace, but heartleaf philodendron often edges ahead — its vines tend to extend a little faster and it keeps growing more readily in lower light. Pothos growth is closely tied to light: bright indirect light produces fast, full growth, while low light slows it noticeably. In a dim Canadian winter, both slow right down regardless.
Can pothos and philodendron be planted in the same pot?
Yes — because their light, water and soil needs are nearly identical, pothos and philodendron grow happily together in one pot, and many people combine them for a fuller look. Just give the pot a position that suits both: bright indirect light keeps a variegated pothos colourful while still suiting the philodendron perfectly.
My plant was sold just as "philodendron pothos" — which is it?
Mislabelling is extremely common, and "philodendron pothos" is not a real plant — it is a sign the seller was unsure too. Use the petiole test: grooved stem means pothos, smooth round stem means philodendron. Whichever it turns out to be, care for it exactly the same way; the label matters far less than the plant's actual light and water.
