Jewel Orchid Terrarium: How to Grow Jewel Orchids Under Glass

Jewel orchids look like they belong in a fantasy greenhouse.

Velvet leaves, electric veins, dramatic colors – they’re foliage plants first and orchids second, at least from a terrarium design perspective.

That’s what makes them so useful behind glass. They bring far more visual impact than their size suggests, and in the right setup, they can be surprisingly natural terrarium plants.

The trick is not treating them like ordinary terrarium filler.

Jewel orchids need humidity, yes, but they also need careful moisture, good drainage, and enough airflow to keep things fresh. Get that balance right, and they’re some of the most rewarding plants you can grow in a tropical terrarium.

In this guide, I’ll show you which jewel orchids work best in terrariums, how I’d plant them, and what to avoid.

Jewel orchids are some of the best orchids for terrariums, but not because they behave like typical orchids.

Most orchids people grow indoors are epiphytes, adapted to clinging to bark and branches with lots of air around their roots. Jewel orchids are different. They’re terrestrial rainforest plants, which means they naturally grow in loose, organic material on the forest floor.

That makes them a much better fit for most tropical terrariums.

They stay relatively compact, appreciate steady humidity, and bring the kind of foliage that can carry a whole display on its own. You’re not waiting for a brief flower show here. With jewel orchids, the leaves are the point.

In a terrarium, they can work beautifully as:

• A feature plant in a small tropical setup.
• A foreground plant in a larger display.
• A dark foliage contrast against mosses and bright green ferns.
• A collector plant in a dedicated orchid terrarium.

The catch is that they need balance.

Terrariums solve one of the biggest jewel orchid problems – dry air – by keeping humidity high and stable. But that same enclosed environment can become a problem if it gets too wet, too still, or too compacted around the roots.

So the goal isn’t maximum humidity at all costs.

The goal is a lightly moist, breathable setup where the plant gets the benefits of glass without being trapped in stale, soggy conditions.

1. Ludisia discolor

If you’re starting with your first jewel orchid, this is the safest bet.

Ludisia discolor is the most widely available and generally the most forgiving of the group. It has rich dark foliage with bold pink striping, and it tends to handle typical indoor conditions better than fussier species.

In a terrarium, it adds strong contrast and gradually forms a fuller, more structured clump.

It can get larger and leggier than some of the smaller species, so give it a bit of room (in a tiny jar, it may feel too chunky). But in a medium tropical terrarium, it can really come into its own.

2. Macodes petola 

The classic “lightning jewel orchid,” and it earns the name.

Macodes petola has glowing gold venation that looks almost electric against its green leaves. Under soft light, it genuinely shimmers, and in a terrarium setting it can look like one of the most magical plants you’ll ever grow.

I’d argue it works best as a feature plant in terrariums (I mean, just look at it). Don’t bury it in a crowded planting scheme – give it a visible position where the leaves can actually catch the light.

It’s usually less forgiving than Ludisia discolor, though.

This orchid is particularly sensitive to airflow – around the roots and the leaves – so it’s worth considering how you might account for that with substrate aeration and ventilation. More on that later.

3. Anoectochilus 

Within the Anoectochilus genus, there’s no clear standout species – but I’d say it’s a tossup between Anoectochilus chapaensis and Anoectochilus formosanus.

Both are similar to Macodes petola, but instead, they offer a selection of dark leaves.

The jet-black leaves contrast beautifully with the gold and bronze veins. 

Alas, I’ve yet to add these jewels to my collection, but let’s just say that I’ve already purchased some perfectly petite glassware.

Jewel orchids do best in warm, humid tropical terrariums with bright indirect light and enough air exchange to keep the setup fresh.

Humidity is often touted as the be-all and end-all of jewel orchid care, but that doesn’t necessarily mean fully sealed.

A closed terrarium can work well, and the extra humidity is certainly helpful, but jewel orchids still appreciate airflow. In practice, that means either using a setup with some natural ventilation or simply opening the terrarium periodically to let in fresh air.

The kind of semi-open, larger cabinet-style or tank-style terrariums can really house these plants well.

That said, my jewel orchid terrarium with both the Macodes and Ludisia plants lasted years in a standard glass container with a loose seal. All I did was open it for the occasional watering, so maybe it’s not as complicated as others make out…

All that to say, I wouldn’t overcomplicate it.

Jewel orchids don’t need a laboratory-grade orchid cabinet, but they do need a setup that stays humid without becoming stale.

Substrate

Substrate is probably the easiest place to get jewel orchids wrong.

They need consistent moisture, but they don’t want to sit in dense, soggy soil. The roots still need air around them, even though these are terrestrial orchids (rather than the bark-clinging epiphytes people usually associate with orchids).

So the best jewel orchid terrarium substrate is moisture-retentive, but loose and breathable.

Think rainforest floor, not houseplant compost.

A good mix should combine moisture retention with plenty of structure. Coco coir, fine bark, sphagnum moss, worm castings, pumice, perlite, lava rock, and orchid bark can all work in different combinations. The exact recipe matters less than the texture: soft, open, and lightly moisture-retentive.

Light

As you might expect from tiny plants found on the rainforest floor, jewel orchids are not accustomed to getting much light.

Just dappled light that’s managed to break through the canopy and reach right down to the bottom.

The brighter the light, the more vibrant the foliage.

Just not direct light, that’s a rapid way to have a crispy dead orchid on your hands…

Grow lights can be super helpful here, especially for terrariums, because they provide steady brightness without the heat risk of direct sun through glass.

Growth

Jewel orchids do vary in size and growth habits. 

The stunning foliage of Macodes petola tends to spread out (and if it’s really healthy, it somehow gets denser at the same time), whereas Ludisia forms much larger and more structured plants.

Being slow growers overall, I don’t feel the need for liquid fertilizers very often.

Just some slow-release nutrients from earthworm castings are usually enough in my experience.

When it comes to the modest white blooms, some people like to pinch them off to direct the plants to direct their energy to their foliage instead. 

I think they’re quite pretty, personally!

In the right setup, jewel orchids are genuinely great for terrariums.

They’re an excellent choice for experienced growers who want dramatic foliage and a bit of a challenge.

Their rainforest-floor growth habit makes them a much more natural fit for terrariums than many other orchids, and their compact size makes them ideal for smaller tropical builds.

For beginners, Ludisia discolor is the obvious place to start. For collectors, Macodes petola and Anoectochilus species can be spectacular additions. Either way, the formula is pretty much the same: warm conditions, high humidity, an airy substrate, careful watering, and enough airflow to keep the setup fresh.

Get that right, and they really do earn the name.
