Herbs as Closed Terrarium Plants

We are going to start with herbs. These are often small, easy to grow, and almost perfect for tropical environments that closed terrariums produce. Here are some of them to consider: 

#1. African Violets (Saintpaulia)

African Violets

The first and probably most attractive plant you can get in a terrarium is the Saintpaulia. As the common name of African Violets says, it produces purple and dark violet flowers. What sets them apart is how small they are, growing not more than 5 inches tall and 10 inches wide.

You’ll need indirect sunrays and moist soil for them to thrive. 

#2. Baby’s Tears (Soleirolia soleirolii)

Baby’s Tears

As soon as you check the plant out, you’ll know where the name comes from. With small round leaves and thin stems, it is a uniquely enticing addition to any terrarium. The plant is super-small nonetheless, growing almost like moss at no more than 2 inches tall. It can grow to more than 20 inches wide.

To grow it, you’ll need consistently humid soil and a lot of light. 

#3. Moth Orchids (Phalaenopsis amabilis)

Moth Orchids

Also known as the Mini Orchid, this plant is one of the rarest types of herbs to plant. Being rare, they are hard to grow and exceptionally good-looking.

Ferns as Closed Terrariums Plants

Because ferns reproduce using spores and don’t require particular environments to thrive, you can grow them on closed terrariums with little effort. However, ferns include over a thousand species. They’re all similar, holding sword-like shapes on their leaves. But they still have small differences. Check them out:

#4. Giant Sword Fern (Nephrolepis biserrata)

Giant Sword Fern

Growing dense and thick, the Giant Sword Fern is an excellent choice for big terrariums. If you have enough space to fit a person or more, you’ll love having a plant like this. The large sword-like leaves make it popular, as it can cover a lot of space. Each leaf can reach 20 inches in length and 11 inches in width.

It is one of the sturdiest tropical ferns, thriving in warm and moist environments. 

#5. Chinese Brake (Pteris vittate)

Chinese Brake

Also boasting a sword-like leaf, the Chinese Brake is super-resistant, withstanding almost any environment. Despite that, they grow slowly, and their leaves tend to be pretty fragile when handled. Having said that, its leaves can grow to over 25 inches long and 10 inches wide. 

To grow it, you’ll only need humid environments with constant sun rays (it’s not picky about soil). 

#6. Fishtail Fern (Microsorum falcata)

Fishtail Fern

While the Microsorum genus includes over a hundred species, the Fishtail Fern is the most popular. Each plant can grow to over 25 inches long and over 15 inches wide.

Golden Clubmoss

The name of Clubmoss comes from the moss-like appearance. But despite its looks, the plant is actually a fern. One exciting feature of this species is the dense and gorgeous appearance, almost a grass-like shrub. It can grow to 8 inches tall and cover a vast space. 

This one requires indirect sun exposure, a humid environment but well-drained soil. 

#8. Hare’s Foot (Davallia canariensis)

Hare’s Foot

It has many similar cousins like the Rabbit’s Foot and Deer’s Foot. Their shape is similar to most ferns, but with a broader bottom and a thinner tip (epiphytical shape). Either way, their leaves are lush green and grow dense but separated, covering a large space of 40 inches wide, growing up to 20 inches tall.

These are always starving, so they require decently damp soil and environments. 

#9. Leather-leaf Fern (Rumohra adiantiformis)

Leather-leaf Fern

In contrast with other ferns, the leaves of the Ruhmora adiantiformis as often thick and bright, adding a particular attractiveness. Their leaves can grow to 10 inches in length and about 2 inches wide. They grow dense and tightly together, achieving a bush-like appearance when adults. 

You will need a tropical environment, meaning a lot of sun rays and humid soil. 

#10. Maidenhair Fern (Adiantum aleuticum)

Maidenhair Fern

One of the most common terrarium ferns is the Maidenhair. The leaves on this plant don’t grow too large, typically staying between 10 and 14 inches in height and no more than 10 inches wide. For that reason, you can plant them almost anywhere, especially in medium-sized terarriums.

These prefer a lot of shade, constant humidity, and well-drained soil. 

#11. Spleenworts (Asplenium trichomanes)


Famous for its attractive intense green and square-shaped lamina, the Asplenium trichomanes grows to about 12 inches tall and between 15 to 20 inches wide. It is a pretty good choice for medium-sized terrariums as well as gardens.

You’ll need humid and shaded places for this plant, and it can grow on almost any type of tropical soil.

Vine Plants for Closed Terrariums

Alongside ferns, vines are the most popular species of plants for terrariums. You can find everything from climbing and creeping to trailing species. As long as its crawls through surfaces, that’s a vine that probably grows effortlessly on terrariums. Here are some to consider: 

#12. Baby Rubber Plant (Peperomia obtusifolia)

Foliage Plants for Closed Terrariums 

Plants that don’t climb but produce dense green areas are often known as foliage. Some of these can come from entirely different species (like palms and shrubs), but they all offer this ability to grow thick and lushly. One of these foliage plants can be an excellent addition to your terrarium:

#19. Elephant Ears (Alocasia & Colocasia)

You can find Elephant Ears of all colors and sizes, covering species like the Alocasia and Colocasia. Some of them can reach over 50 inches in length with 3-feet-large leaves. But others grow no more than 10 inches high and 5 inches wide. Either way, they all boast a triangular ear-like shape.

Despite its unique appearance, it requires constant light and heavily humid soil. 

Mosses as Closed Terrarium Plants

You may believe that moss is for lawns and gardens. And while you wouldn’t be wrong, mosses also thrive in enclosed spaces like terrariums. In fact, they probably prefer places like that due to the high humidity these areas produce. Here are some mosses to consider: 

#27. Haircap Moss (Polytrichum commune)

Haircap Moss

Looking at the Haircap Moss is like looking at a small beach palm. The leaves are often bright green with a red-to-brown stem. Interestingly, this moss can grow to 2 feet in height and cover an area of over 5 feet in diameter. The plant may grow some flowers that look like small fungus. 

They require partial shade and depend heavily on highly fertilized soil with high humidity. 

#28. Pincushion Moss (Leucobryum glaucum)

Pincushion Moss

You could say it looks like a terrestrial coral, and you wouldn’t be out of place. The moss grows to about 5 inches with super-small leafy shrubs that grow to 5 inches tall and can cover 3 feet in diameter. Generally, it comes in a light yet vibrant green that makes it look like a cushiony coral.

It generally demands partial shade and moderate humidity. Though, you can grow it in dry places as well.

This one prefers partial shade and damp places, preferably with consistent rains or watering. 

#30. Common Tamarisk Moss (Thuidium tamariscinum)

Common Tamarisk Moss

It looks more like an herb or fern than it looks like moss, but that makes it so attractive. Like every moss, it forms a wide bed on any surface. More importantly, it can reach 6 inches tall and produce lovely green leaves with a brown stem.

The plant obviously requires a lot of humidity, but it can handle neutral soil and partial shade. 

Carnivorous Plants as Closed Terrarium Plants

Even though carnivorous plants are hard to grow anywhere, they make exceptional plants for an enclosed terrarium. Actually, it’s easier to grow them in an enclosed space like this than it is to grow them outdoors or indoors. Below, we talk about some of them:

#31. Cobra Lilies (Darlingtonia Californica)

Cobra Lilies

Some people call it the Cobra Plant and the California Pitcher. Either way, the Cobra Lily is probably the most enticing of all carnivorous plants. And it’s for a reason. This plant boasts unique colors and shapes, typically found in purple with red tones on its cone-like body. It holds a tongue-like part that hangs from its center.

This plant requires humid places, where it rains a lot and the soil is moist most of the day. 

32. Sundews (Drosera spatulata)


It’s one of the rarest forms of carnivorous plants that would likely thrive on enclosed terrariums. It is gorgeous, boasting a green body with pink pricks coming off it. The pricks are sticky glands that capture insects, as it produces an attractive smell. It can grow to 5 inches tall and about 5 inches wide. 

This one prefers humid areas, yet it can grow on almost any soil (even on rocks and stones). 

#33. Venus Flytraps (Dioanea muscipila)

Venus Flytraps

If you’re looking for an easy-to-grow carnivorous, the Venus Flytrap should be your first choice. It is also the most common type of carnivorous plant, holding long stems with a mouth-like leaf. This leaf closes when an insect poses on it. Then it feeds itself. You can find these stems to reach over 15 inches tall. 

Being one of the easiest to grow, it typically requires medium humidity in both environment and soil. 

Frequently Asked Questions (FAQs)

We went through the best plants you can take to any terrarium. This doesn’t mean these are the only ones. And even more important, there are way more factors to consider before planting. In this section, we talk about these things a bit more in-depth:

Q. How often should you water a closed terrarium?

Ans: It depends on the species you’re planting. However, it’s worth noting that terrariums recycle humidity. That means the vapors coming off the soil typically stick to the walls. This humidity usually falls back again to the plants and soil.
For that reason, it is wise to only water when the soil looks dry. Still, follow the specific species’ needs. You don’t want to water a tropical fern like you would water moss. 

Q. Can I grow other plants in a terrarium?

Ans: Obviously, you can plant hundreds of different species and genera in a terrarium. But you should always go for humidity-loving plants like the ones above. Otherwise, you will either struggle to keep the plant growing or without a disease. 

Q. Should you grow succulents in a terrarium?

Ans: One of the reasons you should only choose humidity-loving for a closed terrarium is the unique environment. Plants like succulents and cacti, for example, won’t thrive because they require dry soils. Humid places like closed terrariums will cause them to get diseases and likely to rot. 

Q. How long can a closed terrarium last?

Ans: It depends on the plants you’re growing and the overall care. Generally, however, terrariums can last over 50 years with expert maintenance. With the right conditions in a small place, you can make one last 20 years without problems. 


So, are you ready to start your own terrarium? It will be a fantastic experience from start to end. You just need to remember how difficult it can be. Luckily, the closed terrarium plants above should make it easier.

If you’re eager to take your chances and try building a terrarium, then start right now. It takes a lot of work and time – but it’s completely worth it. Use our advice and plants above – you won’t regret it.
