I have a soft spot for the two houseplants that seem to survive almost anything: pothos and heartleaf philodendron. In the same way sparrows and squirrels blend into the background until you really watch them, these two trailing vines can sit on a shelf for years while we call them by the wrong name.
Both are aroids, both root readily, both climb if you give them something to grab, and both get sold as “easy indoor vine.” But once you know where to look, the differences are not vague at all. They show up in a few quiet places: the feel of the leaf, the way a new leaf unwraps, the little sheath at the node, and how the stem is put together.
Start with the names
Common names get slippery fast, so here is the simplest anchor:
- Pothos is usually Epipremnum aureum (also sold as devil’s ivy, golden pothos, marble queen, neon, and more).
- Heartleaf philodendron is usually Philodendron hederaceum, and it is also commonly sold under older labels like Philodendron scandens.
They are related, but they are not the same genus. That matters because the structures at the stem and leaf base are built a little differently.
The fastest ID checks
If a friend hands me a cutting and says “Is this pothos or philodendron?” I do three things before I even look at variegation.
1) Feel the leaf
- Pothos: thicker, a little leathery, often with a faint waxy sheen.
- Heartleaf philodendron: thinner, softer, more matte, with a gentle satiny look in certain light.
This is subtle, but reliable once your fingers learn it.
2) Look at the petiole shape
The petiole is the leaf stalk. Turn the plant so you can see it clearly where it meets the stem and the leaf blade.
- Heartleaf philodendron petioles often look rounder in cross-section, and many plants show a visible channel along the top side.
- Pothos petioles often look a bit flatter and broader. Some pothos can show a shallow groove too, so treat this as a supporting clue, not a verdict.
3) Check the node for a papery sheath
- Heartleaf philodendron usually shows a thin, papery sheath (a cataphyll) around new growth. As the leaf matures, that sheath dries into a little brown wrapper near the node.
- Pothos does not usually leave the same persistent papery wrapper behind at each node.
Leaf shape: proportions matter
Both plants can make heart-ish leaves, which is why the confusion never ends. The trick is to look at the sinus (the notch where the two lobes meet) and the overall “flow” of the leaf.
Pothos leaves
- Often more oval to teardrop than truly heart-shaped.
- The notch at the base is usually shallow or uneven.
- Leaves tend to hold themselves flatter and stiffer.
Heartleaf philodendron leaves
- More consistently heart-shaped, especially on mature, well-lit vines.
- The notch is typically cleaner and deeper.
- Leaves often look a bit more drapey, with softer curves.
A small caution from my own windowsill: young leaves on stressed plants can be oddly shaped. Use leaf shape as one clue, not the only clue.
Stem and growth habit
Stem thickness and feel
- Pothos stems are often chunkier and can look slightly zig-zag at the nodes.
- Heartleaf philodendron stems are often slimmer and more rope-like, especially on long hanging vines.
Internode spacing
Internodes are the distances between leaves.
- Pothos often has shorter internodes in decent light, giving a fuller look.
- Heartleaf philodendron often develops longer internodes when light is low, so it can look leggy faster.
Light affects both, of course. If you are trying to improve fullness and leaf size, our Houseplants guide has more care notes and troubleshooting.
New leaves and sheaths
If you want one botanical difference that feels the most dependable, watch how new leaves appear.
Heartleaf philodendron: wrapped growth
Heartleaf philodendron commonly produces new leaves from within a cataphyll, a protective sheath. As the leaf expands, that sheath dries and may hang on as a papery remnant near the node.
- You may see brown, papery strips along the stem. That is normal, not disease.
- New leaves often appear like a rolled spear unwrapping.
Pothos: cleaner nodes
Pothos leaves emerge more directly, and you usually will not see that same persistent wrapper left behind at each node.
Aerial roots: a supporting clue
Both plants make aerial roots because both are built to climb. Indoors, those roots might look like little nubs, brown threads, or short spikes along the stem.
- Pothos often shows one more prominent nub at a node, especially on older vines.
- Heartleaf philodendron often shows slimmer, wirier roots, and you may see them near dried sheath remnants.
There is plenty of overlap here, so I treat aerial roots as confirmation, not the main ID test. The sheath behavior beats everything else.
One small observation I love: if you let either plant climb instead of hang, those aerial roots stop being shy. They get longer, more persistent, and much more purposeful.
Variegation can mislead you
Variegation is the obvious clue people reach for first, and it is also the one most likely to trick you.
- Pothos comes in many familiar variegated forms (golden, marble, pearls and jade, etc.).
- Heartleaf philodendron also has cultivars and color forms (including darker leaves, lighter “lemon-lime” tones, and variegated types).
A green pothos and a green heartleaf philodendron are the classic confusion, but a variegated plant can still be either. Use nodes, sheaths, and petioles to be sure.
Quick sink-side table
| Feature | Pothos (Epipremnum) | Heartleaf Philodendron (Philodendron) |
|---|---|---|
| Leaf feel | Thicker, slightly leathery, often shinier | Thinner, softer, more matte or satiny |
| Leaf shape | Often oval to heart-ish, notch usually shallow | More true heart shape, notch often deeper |
| New growth | Usually no persistent papery sheath | Papery sheath (cataphyll) often visible and dries on stem |
| Petiole | Often flatter, groove can be subtle or variable | Often rounder with a more noticeable channel |
| Aerial roots | Often a more prominent nub per node | Often slender and wiry, sometimes more than one |
Common mix-ups
Satin pothos
There is a third frequent lookalike: Scindapsus pictus (often sold as satin pothos). Despite the nickname, it is not a true pothos. It tends to have thicker, velvety leaves with silvery patterning.
If your plant has distinctly “satin” leaves with silver, pause before deciding it is pothos or philodendron.
Juvenile vs. mature leaves
In their natural climbing habit, both pothos and philodendron can change leaf size and shape as they mature. A small cutting in a pot is basically a juvenile stage. Give it something to climb and time to settle, and you will often see clearer traits.
When pothos gets huge
One more edge case that surprises people: given support, time, and strong light, mature pothos can develop much larger leaves and may even fenestrate, meaning the leaf blade forms splits or openings. Indoors, it is uncommon unless the plant is allowed to climb, but it can make a once-familiar vine look like it came from a different shelf entirely.
My low-tech ID test
If you are already propagating, identification gets easier because the node is right in front of you.
- Cut below a node (either plant roots from nodes).
- Rinse the stem so you can see texture clearly.
- Watch the next bit of growth. Heartleaf philodendron tends to show that papery sheath behavior more plainly as it pushes a new leaf.

FAQ
Does it matter for care?
In day-to-day indoor care, they overlap a lot: bright indirect light, let the top portion of soil dry, do not let roots sit in water, and rotate for even growth. Where it can matter is in growth habit (heartleaf philodendron often looks leggier in low light) and in how you interpret dried sheaths on philodendron stems (normal).
Are either of them safe for pets?
Both pothos and philodendrons contain insoluble calcium oxalate crystals, which can irritate mouths and digestive tracts if chewed. If you share your home with pets or small children who like to sample leaves, place the vines out of reach or choose a safer plant.
Why do some sellers label everything pothos?
Because pothos has become a catch-all nickname for trailing aroids in the houseplant trade. The plants are forgiving, the name is familiar, and tags do not always keep up with botany.
A final nudge
I have met people who feel a little sheepish after realizing their “pothos” is a philodendron, or vice versa. I do not think it is embarrassing at all. It is a sign you are starting to notice the small architecture of a plant, the same way you start to recognize individual birds once you stop calling everything a “brown one.”
