Pothos can get fenestrations, but not every pothos plant will develop those iconic splits and holes.
It’s a natural phenomenon that occurs in certain varieties and under the right growing conditions.
If you’ve been wondering whether your pothos will ever produce fenestrations, the short answer is that mature plants of specific species absolutely can.
In this post, we’ll explore why pothos get fenestrations, what conditions encourage them, and which varieties are most likely to surprise you with those beautiful leaf splits.
Let’s dive into the world of fenestrated pothos and see how you can help your plant develop this sought-after look.
Why Pothos Get Fenestrations
The main reason pothos get fenestrations has to do with the plant’s natural growth cycle and genetics.
Fenestrations in pothos are not a defect — they’re a sign of maturity and optimal health.
When a pothos reaches a certain age and size, its leaves may begin to split or develop holes to better adapt to its environment.
Here are the key factors that explain why pothos get fenestrations:
1. Natural Maturity of the Plant
As pothos age, their leaves naturally change shape and size.
Juvenile pothos leaves are typically solid and heart-shaped.
When the plant matures — often after several years of steady growth — the leaves can become larger, thicker, and start showing fenestrations.
This is especially true for climbing pothos that are allowed to grow upward on a moss pole or trellis.
The more mature the vine, the more likely you’ll see pothos get fenestrations along those older stems.
2. Genetic Predisposition in Certain Species
Not all pothos are created equal when it comes to fenestrations.
Some species, like Epipremnum pinnatum (often called “Cebu Blue” and its varieties), are genetically programmed to produce fenestrated leaves as they mature.
Others, like the common golden pothos (Epipremnum aureum), rarely develop fenestrations unless they reach an exceptionally mature climbing stage.
So when you ask “do pothos get fenestrations,” the answer depends greatly on which pothos you’re growing.
3. Environmental Triggers That Encourage Splits
Even if your pothos has the genetic potential, it needs the right environment to express fenestrations.
High humidity, bright indirect light, and consistent warmth all signal to the plant that it’s time to mature.
When pothos climb up a support and receive plenty of light, they shift from juvenile to adult growth phase — and that’s when fenestrations typically appear.
Without these triggers, your pothos may stay in its juvenile form indefinitely.
Conditions That Encourage Fenestrations in Pothos
If you want to see your pothos get fenestrations, you can create an environment that promotes maturity.
It’s not a guarantee, but these conditions significantly increase your chances:
1. Provide a Climbing Support
Pothos are natural climbers in the wild.
When they climb upward on a moss pole, trellis, or tree trunk, they develop larger leaves with more fenestrations.
Ground‑trailing pothos often stay in their juvenile stage with solid leaves.
So if you want fenestrated pothos, give your plant something to climb.
2. Ensure Bright, Indirect Light
Low light encourages leggy growth and small leaves.
Bright, indirect light fuels photosynthesis and leaf expansion, which is essential for fenestrations to develop.
A spot near an east‑ or west‑facing window is ideal.
Avoid direct sun, which can scorch the leaves.
3. Maintain High Humidity and Warmth
Pothos thrive in humidity levels of 60% or higher.
You can increase humidity with a humidifier, pebble tray, or by grouping plants together.
Warm temperatures between 65°F and 85°F (18–29°C) also encourage mature growth.
Cool drafts or dry air can slow down the process.
4. Be Patient – Fenestrations Take Time
Fenestrations don’t appear overnight.
Even under perfect conditions, it may take two to three years for your pothos to produce its first split leaf.
The plant needs to build enough energy and reach a certain stem thickness before it shifts to adult morphology.
So if you’re asking “do pothos get fenestrations quickly,” the answer is no — it’s a slow, rewarding process.
Common Pothos Varieties That Show Fenestrations
Some pothos are far more likely to develop fenestrations than others.
Here are the top varieties known for producing fenestrated leaves:
1. Epipremnum Pinnatum (Cebu Blue)
This is the most famous fenestrated pothos.
Mature Cebu Blue leaves develop deep splits and a beautiful blue‑green sheen.
It’s a must‑have if you want to see pothos get fenestrations reliably.
2. Epipremnum Pinnatum ‘Skeleton Key’
A rare variety that naturally produces highly fenestrated and elongated leaves.
It’s a climbing cultivar that looks almost like a fern when mature.
3. Epipremnum Aureum (Golden Pothos) – Only at Extreme Maturity
While uncommon, golden pothos can develop fenestrations if allowed to climb for many years.
Most indoor golden pothos stay juvenile, but in greenhouses or tropical climates, mature vines may show small splits.
4. Epipremnum Pinnatum ‘Variegated’
Variegated forms of E. pinnatum also produce fenestrations as they age.
They combine the sought‑after leaf splits with white or yellow marbling.
So, Do Pothos Get Fenestrations?
Pothos do get fenestrations, but only under specific conditions.
Maturity, climbing support, bright light, and proper humidity are the key factors that trigger fenestrations in pothos.
Not every variety will produce them, but if you choose a species like Epipremnum pinnatum and provide the right care, you can enjoy those iconic split leaves.
Patience is essential, as fenestrations often take years to appear.
Now you know the full story — go ahead and give your pothos the climb it craves, and watch for those fenestrations to emerge.
