Discover the low-maintenance picks that’ll transform your glass garden into a thriving paradise, no green thumb needed!
If you’ve ever dreamed of having a tiny jungle sitting right on your windowsill, you’re in the right place. Tropical terrarium plants make that dream surprisingly easy to pull off.
The best part? You don’t need to be an experienced gardener to get started. These plants are resilient, beautiful, and often thrive with minimal attention once they’re settled in.
No matter if you’re building your first terrarium or adding to an existing one, choosing the right plants makes all the difference. The wrong pick can turn your project into a frustrating mess.
So let’s make sure that doesn’t happen! Throughout this guide, you’ll find everything you need to choose, combine, and care for your plants like a total pro.
Why tropical plants work so well in terrariums
Tropical plants are basically built for terrarium life. They love humidity, they’re used to filtered light, and many of them stay compact enough to fit inside a glass container without taking over.
Think about where these plants come from naturally, dense, layered forests with warm temperatures, consistent moisture, and indirect sunlight. A closed or semi-closed terrarium mimics those conditions surprisingly well.
That’s why, when you pick tropical terrarium plants for your setup, you’re working with nature rather than against it. The environment inside your glass does a lot of the heavy lifting for you.
Additionally, tropical plants tend to bring incredible visual variety. You get bold textures, deep greens, pops of color, and interesting growth patterns, all inside one small container.
Choosing the right plants for your setup
Before you start shopping, it helps to know a little about your terrarium type. Closed terrariums hold moisture and work best for humidity-loving species. Open ones dry out faster and suit plants that like a little airflow.
Most tropical terrarium plants prefer closed or semi-open setups. However, some of the hardier tropical varieties can adapt well to open containers too, especially if you live somewhere warm and humid.
Also consider the size of your plants at maturity. Slow-growing, compact varieties are your best friends here. Fast growers can quickly overcrowd your setup and crowd out their neighbors.
As a general rule, aim to combine plants with similar light and water needs. Mixing a moisture-loving fern with a drier-preference plant, for example, is a recipe for at least one of them being very unhappy. There’s also a complete article about the best closed terrarium plants here!
Top 7 best tropical terrarium plants to grow right now
This is where the fun really begins! Below, you’ll find some of the most popular and reliable tropical terrarium plants that look amazing and are genuinely easy to care for.
Fittonia (nerve plant)
Fittonia is a fan favorite, and honestly, it’s easy to see why. Its leaves are covered in a web of contrasting veins in white, pink, or red, giving it a totally eye-catching look. It thrives in high humidity and low to medium indirect light, making it a perfect match for closed terrariums.
Furthermore, it stays small and grows slowly, so it won’t bully its neighbors., add decorative rocks, and create little landscapes without feeling cramped or restricted.
Peperomia
Peperomia is one of those plants that seems to come in infinite varieties — waxy, wrinkled, round, elongated — and they’re all pretty stunning in a terrarium setting.
These little guys are incredibly forgiving. They tolerate low light and don’t need constant watering, which makes them a great option even for beginners who are still figuring things out.
Selaginella (spikemoss)
Selaginella looks like something straight out of a fairy tale. It forms a lush, carpet-like mat of tiny, feathery fronds that bring an almost magical softness to the terrarium floor.
It loves moisture and shade, so it’s particularly well suited for closed setups. Moreover, it spreads gradually, helping to fill gaps and create that full, overgrown jungle vibe you’re probably going for.
Miniature orchids
Yes, orchids can absolutely live in a terrarium, as long as you choose the right miniature varieties! Species like Lepanthes or Masdevallia are tiny, humidity-loving, and absolutely breathtaking.
They do need a bit more attention than some of the other plants on this list, but the payoff is worth it. A blooming miniature orchid inside a glass container is genuinely one of the most stunning things you can grow.
Begonia (terrarium varieties)
Some begonia varieties are perfectly scaled for life inside a glass container, especially the smaller rhizomatous types. Their leaves often feature gorgeous patterns and textures that really stand out.
Begonias enjoy humidity and indirect light, and they’ll occasionally reward you with delicate little blooms. Consequently, they add both foliage interest and a touch of floral charm to your setup.!
Pilea (friendship plant)
Pilea involucrata, or the friendship plant, has deeply textured, almost quilted leaves that bring a really tactile quality to any terrarium. It’s quirky, compact, and full of character.
It does well in medium indirect light and appreciates consistent humidity. Notably, it’s also a relatively fast grower compared to some others on this list, so keep that in mind when planning your layout.
Cryptanthus (earth stars)
Cryptanthus are bromeliads that grow close to the ground in a flat, star-like rosette shape. They come in an incredible range of colors, greens, reds, pinks, and even striped varieties.
Unlike most bromeliads, they’re terrestrial, meaning they grow in soil rather than attached to trees. That makes them ideal for terrarium planting, and they’re genuinely one of the most visually dramatic tropical terrarium plants you can find.
Caring for your tropical terrarium plants
Once you’ve set up your terrarium, the goal is mostly to maintain balance. Tropical plants in a closed terrarium essentially create their own little ecosystem. For example, water evaporates, condenses on the glass, and drips back into the soil.
That means you might not need to water very often at all. In a well-sealed terrarium, some setups can go weeks or even months without additional watering. However, keep an eye out for excess condensation, which can signal that things are too wet.
Light is equally important. Indirect, bright light works well for most tropical terrarium plants. Avoid placing your terrarium in direct sunlight, the glass acts like a magnifier and can overheat your plants quickly.
If you notice yellowing leaves, leggy growth, or mold developing on the soil, those are signs that something needs adjusting. Most issues come down to too much water, too little light, or poor ventilation, all very fixable!
Combining plants for a lush, layered look
One of the most rewarding parts of building a terrarium is designing how the plants look together. Think about height, texture, and color as three separate elements you’re balancing.
Use taller plants like certain ferns or begonias as the backdrop, mid-height plants like fittonia or pilea in the middle ground, and low-growing spreaders like selaginella as ground cover in front.
| Factor | Effect on watering frequency |
| Terrarium size | Larger terrariums hold more moisture and need water less often |
| Plant types | Moisture-loving plants like mosses cycle water more actively |
| Light exposure | More light = more evaporation = slightly more frequent watering |
| Seal tightness | A tighter seal retains moisture longer |
| Room temperature | Warmer rooms speed up the water cycle |
As you can see, there’s a lot of room to play. Don’t be afraid to experiment — that’s a huge part of what makes terrarium-building so genuinely fun.
Check out mistakes to avoid with tropical terrarium plants
Even with the best plants, a few common missteps can set your terrarium back. Luckily, most of them are easy to avoid once you know what to watch for.
- Overcrowding is probably the most frequent issue. It’s tempting to fill every inch of space, but plants need room to breathe and grow. Start with fewer plants and let them fill in over time.
- Using the wrong soil is another biggie. Regular potting mix can compact and hold too much water. Instead, go for a terrarium-specific mix or a blend of potting soil, horticultural charcoal, and perlite for better drainage.
- Skipping the drainage layer underneath your soil can lead to root rot. A base layer of pebbles or lava rocks helps excess water collect somewhere that won’t drown your plants’ roots.
Reading recommendation: keep building your terrarium knowledge
If you enjoyed learning about tropical terrarium plants, there’s so much more to explore in the world of terrarium design. One great next step is understanding how to use moss effectively in your builds.
Moss is one of the most versatile and forgiving elements you can add to any terrarium. It fills gaps, adds texture, retains moisture, and creates that lush, living-carpet effect that makes terrariums look so magical.
