When Pothos Leaves Do the Splits

Should I be taking my pothos out to a bar to celebrate? Because my blue pothos (Epipremnum pinnatum ‘Cebu Blue’) has reached adulthood … after over 20 years of care, just like a human.

As with many aroids (the best known of which is the so-called Swiss cheese plant, Monstera deliciosa), the pothos has a juvenile form, with smaller, entire leaves, in this case about 3 inches (7 cm) long, and thin stems. Then, as it matures, and if conditions are right, the leaves get bigger and bigger and the stems get thicker.

At some magical point, the plant reaches “adulthood” and the formerly entire leaf becomes huge (up to 2 feet/60 cm long) and begins to split, eventually becoming pinnate, looking like a palm frond, with thick stems. It will even flower at some point (although the blooms are, I’m told, nothing to shake a stick at).

My Story

Leaves of the mother plant are 3 to 4 inches (7 to 9 cm) long and uncut; the largest leaf of the baby is 13 inches (33 cm) long and deeply cut on one side. Photo: Photo: laidbackgardener.blog

I have probably half a dozen blue pothos at my place, most in their juvenile state. In fact, the original plant is still very juvenile. But others are maturing at various rates, with larger and larger leaves. What’s the difference?

It depends on how you grow them.

My original plant grows in a wall pot and is allowed to dangle. Dangling is not conducive to mature growth, so it has only tiny leaves. Dangling is what this tropical Asiatic liana does in the wild when it loses its grip on the tree trunk it is climbing on. As it trails downwards, the leaves get smaller and smaller, then disappear entirely.

When my plant does this (produce bare stems with no leaves), I trim off the bare part to force it to produce more foliage: dangling bare stems are just not that attractive. In the jungle, though, the now bare stem keeps growing downward, eventually reaching the jungle floor when it now begins to creep along, leafless, until it finds a new trunk. Then it will start growing upwards again and to produce small leaves once more. They then get bigger and bigger as it grows up into better light and eventually, the plant reaches adulthood and new giant cut leaves form.

My mature and variously maturing pothos are all growing upwards … on my green wall. Growing upwards is conducive to enlargening leaves. Eventually they get to the top (said wall is only 7 feet/210 cm tall, after all, not the 100 feet/30 m or so the plant can attain in a jungle!), so I cut them off and reroot them at the base of the wall. They don’t lose a beat and continue to grow upwards … and in size.

Actually, I just pulled my mature stem from the wall (it had reached the top) and will be starting it from the bottom again. I’m sure it will continue to mature to even bigger, more deeply cut leaves (the longest is currently 13 inches/33 cm in length and only cut on one side) on its next trip upwards.

Your Pothos

The most common pothos in homes is not my blue pothos, but rather the golden pothos (Epipremnum aureum, syn. Scindapsus aureus), with heart-shaped leaves splashed with yellow or, on certain clones, white.

But it will also grow, eventually, into a jungle giant with large split leaves if you let it grow upwards, say on a moss-covered stake it can root into. When it grows so tall, it begins to stretch beyond the stake, start it all over again. Take cuttings from the large-leaved section at the top and reroot them in a fresh pot of soil, at the base of a new stake. The cuttings will then start to grow upwards again without losing their size (or not much of it) and grow even bigger over time. Repeat as necessary until the leaves are truly giant and deeply cut.

Most people grow it in a hanging container from which it will dangle and thus always remain a juvenile. But if you grow it upwards, you can—slowly!—watch it become an adult.

I think you’ll be kinda proud when your baby pothos reaches adulthood, don’t you?

    Thanks for all the info. Not only did I not know what I bought (“Hello My Name Is Houseplant” is on the Exotic Angel, Costa Farms Badge from Lowe’s), I had no idea it would split like that. Thank you so much for taking the time to post this article — including all the pictures. This is extremely helpful!

    I have a question. I combed the internet looking for an answer after I read your article, but I have found nothing. Maybe you can help. What would happen if instead of removing your plant from the wall and making it continually climb upwards, you instead took a cutting from the nodes of the top big leaves, rooted it in water or soil, and made that cutting start the climb? Does that question make sense? Basically, can you start a whole new plant from the biggest leaves you have instead of zig-zagging it upward every time it reaches the top? Thanks!

    • I’m not sure I totally understand the question, but if you meant can you take a leaf cutting from a pothos or other aroid climber, the answer is no: they won’t root from a leaf cutting. You need at least a piece of stem with a leaf for rooting to occur. And if you cut the stem, the plant will no longer be climbing (until a new one grows in.

        Thank you for replying!

        Sorry my question was a bit convoluted. When the pothos is small (say, in a hanging pot), you can cut a piece off of the hanging stem — with the leaf, at the node, where the air roots are coming out…place that leaf and node in water…roots develop.. and viola, you have new plant to put in soil. My question was whether you could take the same sort of cutting from the top of your plant, where the big leaves are (at the node, with the stem and leaf), root that in water, and make another plant that already has big leaves that ultimately only get bigger when the plant starts to climb. Does that make sense?

      • Got it! Yes, you can. It will at first produce slightly smaller leaves than the one you harvested, but it will already be on the road to increasing in size, so as long as you grow it so it’s directed upward, it will soon produce leaves as big at the first one, then bigger ones.

    That is amazing!!! It will take my Cebu a long time before it ever reaches anything close to your size, but I can’t wait. I love watching things grow. Thanks so much, again, for sharing all your knowledge.

    Cebu blue! So beautiful! Can’t find them in Quebec that I’ve seen and I’ve been hunting a LONG LONG time (unless I want to spend about $50)

    Thanks for a great read!

    Do you need to retrain the cuttings on to the wall or do they attach on their own? Do you find they prefer to grow in to a straight line versus wrapping around a pole?

    • If the wall is humid, they’ll quickly root onto it. The stems don’t wrap (they’re not twiners like some climbing plants), but they’re not necessarily 100% straight, either. You’ll find they’ll head towards the spot with the most light or will work their way around obstacles.

    Hi there, hadn’t paid my epipremnum aureum much attention before your post here. But now I’m genuinely fascinated! Really wish I could grow my epi to impressive maturity. I’ve tried to find more infos on mature epipremnums, but aside from the aureum I haven’t really found much else, so I thought maybe you know: Which other of the epipremnums produce split leaves as they mature? And do the leaves of all epipremnums, especially the N’joy, grow in size after a time? Do these “new” cultivars even grow in the wild?? Thanks a lot in advance for answers. So interested!

    • Few species of Epipremnum are cultivated. All seem to have leaves that grow considerably in size as they grow, but not all have split leaves at maturity. I do know that E. aureus and E. pinnatum have split leaves. Njoy is a small-leaved, more highly variegated selection of E. aureus ‘Marble Queen’ which does grow large leaves that eventually split when they grow upwards. However, I’ve never heard of anyone growing Njoy other than as a trailing plant, so can’t say if they get larger and eventually split. You’d think they would, given its parentage. It’s a new cultivar, only launched in 2009, so has probably not been fully tested yet.

    Hi! It’s amazing to learn this about this plant I’ve felt familiar with most of my life! I feel like I never really knew it at all! Noob question here… What do you mean by cut it back, reroot it, and plant it at the base of the stake? Based on some of the comments I’m guessing that means remove it from the stake and replace it so the stem is poised to climb the stake again…is that about right? And what do you do with the length of stem now looped at the base?

    • I’ve rewritten that section make it easier to understand (I hope).

      Here goes:

      “When it grows so tall it begins to stretch beyond the stake, start it all over again. Take cuttings from the large-leaved section at the top and reroot them in a fresh pot of soil, at the base of a new stake. The cuttings will then start to grow upwards again without losing their size (or not much of it) and grow even bigger over time. Repeat as necessary until the leaves are truly giant and deeply cut.”

    Hi, Thank you very much! Ihave been searching for a more in-depth explanation for a while now. I have a question: Your article states that the Epipremnum NEEDS to grow upwards to reach maturity, however: I have a staked Epipremnum reaching maturity(6 inch leaves on the top) which grows down the pole again after reaching the top of the moss stick, while she is still air-rooting in the moss(peat)pole while growing downwards. A decrease in the size of its leaves has yet to be noticed, are you sure the plant necessarily has to grow up, or is it also a possiblity that an Epipremnum just needs a tree-like medium to root its stems to reach maturity?

    • Kee Kee

      I’m no expert, but there are two things to note:

      First, I think your plant is still technically “climbing” in a sense. Even though it’s growing downward, its air roots are anchoring into the moss pole and therefore, still “climbing” and not “hanging.” I think the author of this article is speaking specifically of “climbing” vs “hanging.” If you ONLY let the plant hang, it won’t ever increase its leaf size. You MUST allow it to climb to get larger leaves.

      Secondly, since you allowed it to climb, it grew 6″ leaves and it won’t immediately lose its leaf size even if you were to allow it to trail. After reading this article a year ago, I took a cutting from an extremely mature golden pothos with 18″ split leaves, from about 14 ft high in my tree. I DID NOT stake it. I rooted it and just allowed it to hang from its pot. The leaf has some sort of memory because the initial trailing/hanging leaves that grew from it were over 10 inches. Over the past year, though, the leaves have decreased to about 8 inches. I suspect they will keep decreasing as it continues to grow because it is hanging. However, for my trailing pothos that have regular/tiny leaves that you typically see in nurseries, they will NEVER have large leaves unless they are staked. That is what the author is teaching.
