Best Plants for Terrariums
First, to determine what plants are best, we need to get clear on what a terrarium is exactly.
By definition, a terrarium is a sealed ecosystem that acts as a miniature tropical climate.
So, the best terrarium plants are tropical plants that are well adapted to that environment – lovers of humidity, moisture, warmth, and indirect sunlight.
Makes sense, right?
But, of course, not all tropical plants will be a good fit. I can’t see a giant Alocasia being particularly suitable for a desktop terrarium. So, what makes a closed terrarium plant…the best?
- 1. Small plant size – you’re typically working with limited space, so small plants and miniature varieties are more suitable.
- 2. Easy care requirements – any plant parent knows some plants are significantly more straightforward to look after than others. Being tolerant of different moisture levels and low light is very helpful in a closed terrarium.
Short on time? Here’s a quick introduction to the best terrarium plants:
- Fittonia (Nerve Plants)
- Syngonium (Arrowhead Plants)
- Epipremnum aureum (Pothos)
- Pilea (Friendship Plants)
- Ferns (e.g., Lemon Button Fern)
- Ficus pumila (Creeping Fig)
- Peperomia (Radiator Plants)
- Selaginella (Spikemoss)
- Hypoestes phyllostachya (Polka Dot Plants)
- Moss (e.g., Cushion Moss)
Next up, we’re deep-diving into each of these terrarium plants (and giving our top recommendations for each!).
The 10 Easiest Closed Terrarium Plants
1 | Nerve Plants (Fittonia)
Let’s channel our inner Julie Andrews and start at the very beginning (it really is a very good place to start).
Known for its striking, contrasting venation and amazing colors, Fittonia is the quintessential terrarium plant and absolutely perfect for beginners.
They’re fabulously striking and super easy to care for.
A Nerve Plant will tell you when it needs more water. A plant with dramatic flair, it will literally faint and spring back to life once it’s had a drink.
Easy to interpret = easy care.
2 | Syngonium
Oh Syngonium, the unsung terrarium hero.
This one is for you if you’re a fan of bold colors, funky leaf shapes, and remarkable variegation (who isn’t?!).
This beautiful species often gets overlooked on terrarium plant lists, and I cannot understand why.
Both stunning and easy to care for, they’re terrarium plant superstars, and it’s time to give them their moment in the limelight.
And with literally 30+ species and likely hundreds of exciting varieties, there’s something for everyone.
3 | Pothos (Epipremnum aureum)
Despite being beloved houseplants, Epipremnum are considered wild, invasive growers in tropical climates. They’re so aggressive they’ve even been banned in some places!
Why is this relevant? Well, they’re very easy to care for in humid conditions and, honestly quite challenging to destroy.
If you plant a rooted cutting in a terrarium, it’s almost guaranteed to thrive.
Ultimately, you can put any type of Pothos in a terrarium, but as you can probably imagine, some varieties are more appropriate than others when considering longevity.
The following varieties are slower, more compact growers with shorter leaf internodes (the space between each leaf on the stem), making them much better suited for terrarium life.
- Manjula Pothos – heart-shaped leaves and creamy, half blotched, half speckled variegation.
- Njoy Pothos – small, irregular leaves with patchwork green and cream variegation.
- Pearls & Jade Pothos – a much more speckled version of the Njoy.
Though it’s a faster grower, the new Global Green Pothos also has short leaf internodes too – the plant patent states around 1 inch in length.
4 | Pilea
Known for being easy-to-care-for houseplants, Pilea are even easier terrarium plants.
They fit nicely into two functional categories, depending on what you need for your project:
1 | Larger feature plants with interesting foliage – Pilea involucrata (Friendship Plant), Pilea mollis (Moon Valley Pilea), Pilea peperomioides (Chinese Money Plant) & Pilea cadierei (Aluminum Plant).
These kinds of Pilea will be planted terrestrially as the main event.
These plants are typically the last thing to add to a terrarium. Just pop a few cuttings wherever you’d like to add some texture, and over the coming days and weeks, they’ll root up and settle in.
5 | Ferns
Ferns are great terrarium plants, or rather, more specifically, well-behaved ferns are.
Reliable, honest ferns you’d take home to meet your parents, not booty-call ferns that give you the hot and cold treatment and make you hate yourself.
Don’t act like you don’t know exactly what I mean…
Here are some great options that will treat you right:
- Silver Ribbon Fern – Pteris cretica ‘Albolineata.’
- Lemon Button Fern – Nephrolepis cordifolia ‘Duffii.’
- Crispy Wave Fern – Asplenium nidus.
- Fluffy Ruffles Fern – Nephrolepis exaltata.
- Mini Rabbits Foot Fern – Davallia fejeensis.
- Button Fern – Pellaea rotundifolia.
6 | Creeping Fig (Ficus pumila)
Okay, I get a little too enthusiastic about this plant. But you’ll soon understand why.
Ficus pumila is arguably the easiest terrarium plant there is. Planting? No need! All you need to do is carelessly drop a cutting or two in the container, and it will do the hard work for you.
It roots up and grows ridiculously quickly in a humid environment, filling your terrarium with adorable green leaves.
There are three main varieties:
- The classic.
- The classic, but with variegated leaves.
- Ficus pumila quercifolia (with an oak leaf shape).
7 | Peperomia
Pretty much the entire Peperomia genus is terrarium-ready, and there are a lot of them.
With a taste for indirect light and a love of humid conditions, it’s such a set-and-forget genus. You know they will be happy in a terrarium, so you can leave them to do their thing stress-free.
Broadly, they can be categorized into vines, foliage, and large, and I’ll give you a few examples for each.
- Vines – the genus is full of trailing vines with perfectly rounded leaves. Plants like Peperomia ‘Pepperspot’ (String of Coins), Peperomia prostrata (String of Turtles), and Peperomia rotundifolia (Trailing Jade) are marvelous.
- Foliage – Pretty feature plants such as Peperomia argyreia (Watermelon Peperomia), Peperomia caperata ‘Rosso,’ and Peperomia albovittata ‘Piccolo Banda’ will add an interesting dimension to your project.
- Large – Peperomia with broader, glossy leaves, such as Peperomia obtusfolia (Mini Rubber Plant) and Peperomia ‘Ginny,’ make a beautiful statement.
I could go on and on, but this is plenty to get you going, and I’m beginning to grow grey hairs.
8 | Selaginella/ Clubmoss/ Spikemoss
Selaginella is a unique genus, and its somewhat weird features make it a perfect choice for terrariums.
Both visually and characteristically, they can easily be mistaken for mosses or ferns. They behave like carpeting mosses, creating a thick mat as they grow, and like ferns, they’re spore-producing.
This can make Selaginella shopping rather challenging. As you can see by the title, they go by many names.
A great place to start is with Selaginella kraussiana (Golden Clubmoss). It has tiny, scaled green leaves. Perfect for a dense, lush ground cover.
And if you want a splash of contrasting color, my favorite is Selaginella uncinata (Peacock Fern), which looks similar to the kraussiana, but has dreamy iridescent blue tones.
I’ve honestly never known such a hardy plant.
When I bought a cutting, I pretty much forgot about it. It was on some moist sphagnum moss in a sealed Tupperware box in dim light conditions. When I opened it a few weeks later, it had nearly doubled in size.
9 | Polka Dot Plant (Hypoestes phyllostachya)
Honestly, the Polka Dot Plant is very similar to the Fittonia that we began this list with, despite evolving on other sides of the planet.
This plant has spots instead of venation and a tricker name to pronounce.
They come in various brilliant bright colors, with many combinations of red, white, pink, and green leaves. Sometimes the spotted variegation can even blur into patches.
And similarly to Fittonia, it’s super easy to care for in a terrarium. It loves a warm, moist environment, so you can’t go wrong with it.
10 | Moss
When it comes to caring for moss, there’s not much to it.
Because moss needs a humid environment out of direct sunlight, the closed terrarium itself will do the hard work for you. Just keep it moist, and you’ll be rewarded with lush green vibrancy.
No roots = no risk of root rot.
There are two main types:
- 1. Sheet moss (e.g., Hypnum Moss) is great for beginners; it’s effectively a ready-made carpet that will cover the ground of your terrarium. Easy!
- 2. Clumpy moss (e.g., Cushion Moss) is gorgeous but more challenging. Not in terms of care, but in that it’s more challenging to place. It has a thick, fibrous underside that holds the moss together, which needs to be trimmed off; once it’s off, it’s tricky to hold the moss clumps together as you place them.
Ultimately, you can choose whichever moss you fancy, as both sheet and clumpy mosses will thrive. But if you’re going for a clumpy moss, you might need a pair of aquascaping tweezers to make the job easier.
Unless you’re up for a real challenge, stay clear of aquatic mosses like Java Moss – they need extremely humid terrarium conditions that are hard to achieve.
Plants Beginners Should Avoid
Surprised you haven’t seen Prayer Plants, Jewel Orchids, and Air Plants on this list?
Despite being a good fit for closed terrariums, they’re far more sensitive to airflow.
That means you need to keep a closer eye on them and take the lid off every once in a while, which means you’ll need to rebalance the humidity and water content more.
So they are good terrarium plants, just not the most straightforward.
Carnivorous plants have no place in this article either. While some are more suited to terrarium life than others, they’re anything but beginner-friendly (in fact, Venus Flytrap terrariums are almost impossible).
Finally, avoid cacti, succulents (such as a jade plant), and other arid plants like the plague.
Because these guys prefer dry conditions, they’d quickly struggle inside a closed glass container.
Instead, they will need an open terrarium, which isn’t technically a terrarium at all, but we let them off because they’re cool. Feel free to join the dark side if that sounds more like your thing.
