Quick answer: The best all-round bioactive terrarium plants are pothos, heartleaf philodendron, Fittonia, creeping fig, lemon button fern, bird's nest fern, Neoregelia bromeliads, small peperomias, Marcgravia and live moss for humid builds. For desert and semi-arid builds, pick haworthias, gasterias, dwarf snake plant and elephant bush. Below are 100 plants sorted by category, each with its size, light, humidity and the builds it suits. To match plants to your exact enclosure and animal, use our free Bioactive Plant Planner.
How we chose these 100 plants
Most "top 100 terrarium plants" lists are padded with duplicates (five kinds of Fittonia), house plants that rot in a vivarium, or plants that are toxic to the animals they are paired with. This list is built from the plant data behind our Bioactive Plant Planner, with a few rules:
- One entry per plant. Where there are many cultivars (pothos, Fittonia, Neoregelia), we list the best representative and mention alternatives in the notes or the linked guides.
- Proven in enclosed builds. Every plant here grows well in a terrarium or vivarium with the light and humidity listed, not just on a windowsill.
- Matched to the right builds. Humid-loving plants are listed for tropical builds only, and succulents for arid and semi-arid builds only.
- Honest about safety. Plants that irritate if eaten, such as pothos and philodendron, are fine with insect-eating animals but are flagged as unsuitable for herbivores like tortoises and uromastyx.
How to read the tables
- Size: small plants suit nano and dart frog vivariums; medium plants suit 45 cm and larger; large plants need tall or wide enclosures (or regular pruning).
- Light: low means a basic LED is enough; medium needs a decent planted-tank LED; high needs strong LEDs or, for desert plants, bright light close to the plant. See terrarium lighting for plants for PAR and Kelvin basics.
- Humidity: the range the plant is comfortable in long-term. Most tropical plants want good airflow as well as humidity; stagnant air causes rot. Our guide to humidity and ventilation explains the balance.
Vines and climbers (1–12)
Vines are the backbone of most tropical builds. They cover backgrounds, give arboreal animals cover and climbing routes, and bounce back from damage. Our guide to the best pothos and philodendron for terrariums compares cultivars.

Bromeliads (39–46)
Tank bromeliads hold water in their central cups, which gives dart frogs places to deposit tadpoles and tree frogs places to drink. Mount them on cork or wood rather than burying the base, which tends to rot. Read bromeliads in vivariums for mounting tips.
| # | Plant | Scientific name | Size | Light | Humidity | Best builds | Notes |
|---|---|---|---|---|---|---|---|
| 39 | Neoregelia 'Fireball' | Neoregelia 'Fireball' | Small | Med–high | 60–90% | Dart frog, tree frog | Small, bright red in good light, and pups freely. A dart frog staple. |

Air plants (47–49)
Most Tillandsia rot if they stay wet, so only a few suit vivariums. Mount them high, near ventilation, where they can dry within a few hours of misting. The air plant guide explains placement.
| # | Plant | Scientific name | Size | Light | Humidity | Best builds | Notes |
|---|---|---|---|---|---|---|---|
| 47 | Tillandsia brachycaulos | Tillandsia brachycaulos | Small | Med–high | 50–80% | Ventilated tropical, chameleon | More tolerant of humid vivariums than most air plants. |

Begonias (64–68)
Small rhizomatous and species begonias bring colour and pattern to humid builds. Many of the miniature species actually grow better in a vivarium than in an open room. Note that begonias irritate if eaten, so keep them away from herbivores. More in begonias for terrariums.
| # | Plant | Scientific name | Size | Light | Humidity | Best builds | Notes |
|---|---|---|---|---|---|---|---|
| 64 | Begonia prismatocarpa | Begonia prismatocarpa | Small | Low–med | 70–100% | Dart frog, closed jar | Miniature begonia with yellow flowers; perfect for small builds. |

Upright accent plants (74–80)
Upright plants give height and structure, and tougher ones like Janet Craig and Schefflera stand up to heavier snakes and lizards. Most are irritants if eaten, so they suit insectivores and carnivores rather than herbivores.
| # | Plant | Scientific name | Size | Light | Humidity | Best builds | Notes |
|---|---|---|---|---|---|---|---|

| 80 | Dwarf umbrella tree | Schefflera arboricola | Large | Med | 40–80% | Large tropical, chameleon | Woody stems give climbing routes and take weight. |
Mosses (81–84)
Live moss softens hardscape, holds moisture and gives microfauna somewhere to live. Most terrarium mosses need moderate light, airflow and frequent misting rather than constantly wet conditions. Read how to keep live moss green, then browse our fresh mosses, including fresh sheet moss, fresh frog moss and live sphagnum moss.
| # | Plant | Scientific name | Size | Light | Humidity | Best builds | Notes |
|---|---|---|---|---|---|---|---|

Carnivorous plants (85–86)
Most carnivorous plants need more light than a vivarium provides, or a cold winter dormancy, so we have only included two that genuinely suit humid tropical builds. Sundews may occasionally catch springtails, which is harmless to the colony.
| # | Plant | Scientific name | Size | Light | Humidity | Best builds | Notes |
|---|---|---|---|---|---|---|---|
| 85 | Lance-leaved sundew | Drosera adelae | Small | Low–med | 70–90% | Dart frog, tropical | One of the few sundews that tolerates lower vivarium light. |

Paludarium and water-edge plants (87–90)
These plants grow at the waterline, mounted on wood or stone, or with their roots in saturated substrate. They are ideal for paludariums and frog water features. See how to build a paludarium with driftwood.
| # | Plant | Scientific name | Size | Light | Humidity | Best builds | Notes |
|---|---|---|---|---|---|---|---|
| 87 | Anubias nana 'Petite' | Anubias barteri var. nana 'Petite' | Small | Low | 70–100% | Paludarium, dart frog water features | Grows mounted in or above water; never bury the rhizome. |

| 90 | Dwarf sweet flag | Acorus gramineus 'Pusillus' | Small | Med | 60–100% | Water edges, riparium | Grassy tufts that like wet feet. |
Arid and semi-arid plants (91–100)
Desert and semi-arid builds for leopard geckos, bearded dragons, uromastyx and tortoises need plants that tolerate dry air, strong light and some trampling. Plant them in a sandy, free-draining substrate such as Jurassic ABG Semi-Arid Blend, and keep them away from the hottest part of the basking zone. More choices are in the best plants for desert and semi-arid enclosures.
| # | Plant | Scientific name | Size | Light | Humidity | Best builds | Notes |

Plants we left off, and why
Some plants appear on many terrarium lists but cause problems in real builds:
- Lucky bamboo (Dracaena sanderiana): usually sold grown in water and often struggles once planted into a vivarium. Better upright options are listed above.
- Aloe in tropical builds: aloes rot in constant humidity. They only belong in arid builds, and even then many keepers avoid them around animals that might chew them.
- English ivy (Hedera helix): toxic if eaten, temperate rather than tropical, and prone to pests indoors.
- String of pearls in humid builds: the bead-like leaves rot quickly at tropical humidity. String of hearts is a better trailing succulent for semi-arid builds.
- Venus flytrap: needs full sun and a cold winter dormancy that a heated vivarium cannot give it.
- Spiny cacti: a hazard to animals' eyes and skin. Choose spineless Opuntia instead.
Before adding any plant, check it against our reptile-safe plants and toxicity guide, especially for herbivores.
Planting tips for a bioactive build
- Use a living substrate. Tropical plants root best in an ABG-style mix such as Jurassic ABG Terrarium Mix over a drainage layer.
- Clean new plants. Rinse roots, remove old potting soil and check for pests and slow-release fertilizer beads before planting.
- Grow in before adding animals. Giving plants two to six weeks to root makes a huge difference; see how to grow in a bioactive terrarium.
- Mount epiphytes, do not bury them. Bromeliads, orchids, air plants and epiphytic ferns belong on cork bark or wood. See how to mount plants on cork bark and wood.
- Feed lightly, if at all. A bioactive soil and clean-up crew recycle nutrients. If plants need a boost, use a gentle organic option and read how to fertilize terrarium plants safely.
- Plan by enclosure, not by list. The Bioactive Plant Planner filters plants by enclosure size, animal, light and humidity so you do not overcrowd a small tank.
FAQ
What is the easiest plant for a bioactive terrarium?
Pothos is the easiest for medium and large tropical builds, and Fittonia, lemon button fern and creeping fig are the easiest for smaller ones. For desert builds, zebra haworthia and dwarf snake plant are the most forgiving.
Are pothos and philodendron safe for reptiles?
They contain calcium oxalate crystals that irritate the mouth if eaten. They are widely used and generally fine with insect-eating geckos, snakes and frogs that do not eat plants, but they are not suitable for tortoises, iguanas, uromastyx or other herbivores.
How many plants do I need in a bioactive terrarium?
Enough to cover roughly half to two-thirds of the visible surfaces once grown in, with room to grow. A 45 x 45 x 60 cm vivarium might start with six to ten plants. The Bioactive Plant Planner suggests a mix based on your enclosure size.
What plants work in a bearded dragon or leopard gecko enclosure?
Use arid and semi-arid plants such as haworthia, gasteria, dwarf snake plant, elephant bush and spineless prickly pear, in a free-draining sandy soil. For bearded dragons and other grazers, favour edible plants like elephant bush, Opuntia and dandelion.
Can I use plants from my garden or the woods?
It is best not to. Wild and garden plants can carry pests, pesticides and fertilizers, and collecting native plants can harm local habitats. Buy plants from a nursery, then clean and quarantine them before planting.
Why are my terrarium plants rotting?
Rot is usually caused by too little airflow, waterlogged soil or a plant that wants drier conditions than your build provides. Improve ventilation, check that your drainage layer is not flooded, and match plants to your humidity using the tables above.
