Let’s face it, we all love a good Monstera.
And though this silver fox is pretty unique amongst its family, it’s an undeniable beauty.
Living quite the double life, the juvenile form of Monstera siltepecana actually looks completely different from its mature form.
Though it can form those characteristic Monstera fenestrations (the split leaves/holes) at full maturity, its juvenile form has full lance-shaped leaves with a gorgeous silvery hue and dark green veins.
It’s this versatility that makes the Silver Monstera a fantastic option for homes and terrariums alike.
Though not a difficult plant to keep, growing this species to maturity requires a special condition to be met. So, in this article we’ll tell you exactly what you need to do to get the most out of your Monstera siltepecana!
What is the Monstera siltepecana? (& Why it’s Special)
Native to a variety of South and Central American regions, this species of Monstera is a much stronger viner than others in the family, and it really likes to climb.
In fact, to really nurture this plant you’ll need to give it something to climb.
That’s because though the juvenile version of Monstera siltepecana is a happy terrestrial plant (usually found growing at the base of a tree) the mature version is more of an epiphyte.
In the wild, it needs to grow up that tree trunk to complete its growth cycle.
So, if you want this plant to develop into its full expression, you’ll need to support it with a large branch or moss pole. Alternatively, it’ll happily grow as an epiphytic creeper if it has nothing to climb.
(Just note, the size of the juvenile version is more suited to terrarium life, and only the largest terrariums can support a mature Monstera siltepecana).
Monstera siltepecana Care & Growth
At a Glance

|Watering||Regular, even moisture|
|Humidity||High humidity (60-90%)|
|Growth||20-30 inches in juvenile form|
As with many houseplants and other Monstera species, this plant can handle short periods of direct sunlight, but will do best in a really bright spot out of direct sunlight.
Which makes sense when you consider that growing in the wild – terrestrially at the base of the trees or on them epiphytically – the Silver Monstera would predominantly receive filtered sunlight through the forest canopy, and periodic direct light as the Sun passes over the sky.
For those in a the Northern Hemisphere, North and East-facing windows are your best bet (see our Guide to Bright Indirect Light for more help).
Generally, Monstera siltepecana is a pretty forgiving with its light requirements and can survive lower lighting conditions, but just don’t expect it to burst with growth.
Currently my plant is in a shadier spot that’s averaging around 100 footcandles (as that’s the only place I can fit the tall stakes…) though it did most of its growing in a brighter area getting around 200 footcandles.
Monstera siltepecana is a tropical species so it definitely appreciates regular moisture, but then it’s also a partially epiphytic vine so it won’t appreciate being sat in a soggy substrate.
Growing in the wild as an exposed vine, they’ll be thoroughly soaked from the rain and then dried from the Sun. So, matching your watering cycle to that in the home will yield good results.
As with many tropical plants, drainage holes in your pots are a must to divert excess water and prevent root rot.
In a terrarium, there’s a balance to be struck, but choosing the right substrate is half the battle and drainage layers can help.
Depending on its level of maturity it may need slightly different watering requirements, but they’re likely to thrive in most tropical terrarium setups (especially if they have lots of humidity).
Substrate / Soil
Monstera siltepecana does best in a nutrient rich substrate mix with excellent drainage.
As a potentially epiphytic grower, it’s likely going to do better in a chunkier, well-aerated mix too. Something that can really let those roots breathe.
Opting for a mix high in orchid bark and coco coir can really provide that much-needed water retention whilst still allowing for lots of aeration and drainage.
Temperature & Humidity
To be honest, Monstera siltepecana has very typical temperature and humidity requirements.
For most people, your average household conditions will be sufficient to keep these happy enough. Anything above 55°F (12°C) and 50% humidity is fine (and I honestly don’t know how you cope if your house is colder than that).
That being said, as a semi-epiphytic tropical species, you bet it’s going to appreciate every extra degree and humidity percentage it can get.
Humidifiers and pebble trays can help no doubt, but a closed terrarium is the best way to really recreate its natural environment and help it thrive… but of course I’m biased.
We’ve already touched on the particulars of this plants’ evolution, and so it’s really down to you and what you want.
Do you prefer the look of the delicate silver vine or the fully perforated mature leaves?
Under most terrarium conditions, this species is likely to stay in its juvenile form and therefore relatively compact. Which is realistically going to be necessary to keep them terrarium-sized.
On the flip side, if given enough space to grow epiphytically as indoor plants, Monstera siltepecana may mature into the larger version with those characteristic holey green leaves up to 5 inches in size (though they will lose the silver colouring in the process).
Fenestrations can reportedly take several years to appear when grown as a houseplant – so you’ll need some patience with this one!
Monsteras are known for being champion propagators, and the Silver Monstera is no different.
Stem cuttings will propagate super easily. Just make sure to cut a length of stem with at least one leaf and behind a node to make sure the cutting has a point to root from.
They’ll rapidly form roots in water at which point you can put them right back into a substrate.
Varieties & Similar Plants
Monstera dubia and Monstera Peru share some similarities to Monstera siltepecana in that they’re also lesser known climbing species that lack fenestrations (at least in juvenile form).

Goes Well With
In the home, these easy growers are an easy fit for many indoor plants, but in a terrarium you’ll want to pair this with other (potentially) larger species that appreciate plenty of moisture but lots of drainage.
- Philodendron hastatum (Silver Sword Philodendron)
- Calathea ornata (Pinstripe Plant)
- Phlebodium aureum (Blue Star Fern)
- Calathea orbifolia
Frequently Asked Questions
Yellow leaves are usually a sign of overwatering. So, if you see your Monstera siltepecana beginning to yellow then it’s probably time to let it dry out in the pot (or open up your terrarium if that’s where you’re growing it).
Monstera siltepecana is far from the most common in the Monstera family, but these days it’s not particularly difficult to expensive to source.
Monstera siltepecana are a relatively fast growing vine, able to quickly climb or trail depending on their environment.
As Monstera siltepecana matures, it can begin to develop smaller holes in the leaves near the central vein. At full maturity, this species can really express the more classic Monstera fenestrations with a combination of split-leaves and central holes.
