For most tropical plant setups, I’d start with Josh’s Frogs 12x12x18 Tropical Vivarium Plant Kit: it is built around a defined vivarium size, making the plant-and-enclosure match clearer than with loose miniature plants. The 12x12x20 Crested Gecko Vivarium Plant Kit suits a taller enclosure, while LuckyRunes’ 24-piece glass set is a standout for shoppers who want a decorative kit with live moss. The main tradeoff is between a coordinated setup and the freedom to choose individual plants; pack size, plant variety, and enclosure dimensions also affect the fit. I compare all eight options by how well they support tropical terrarium planning, not just by how many plants come in a pack. Continue reading for the full breakdown and help choosing the right starting point.

Key Takeaways

  • Two Josh’s Frogs kits stand out for enclosure-led shopping: the 12x12x18 kit and taller 12x12x20 kit make sense when those dimensions match your vivarium.

  • Plant packs differ more by variety than by enclosure support: the assorted six-plant and ten-plant options offer selection, but buyers still need to plan the layout and growing conditions.

  • Small packs can be a deliberate choice: two or three miniature plants suit a compact build or a gradual start, while larger assortments are better for filling more space.

  • Fern-focused packs narrow the plant palette: the three-plant and six-variety fern options suit shoppers prioritizing miniature ferns over a mixed assortment.

  • The LuckyRunes kit takes a different approach: its glass set and live moss are oriented toward a decorative, ready-to-arrange project rather than a vivarium plant kit tied to stated enclosure dimensions.

  1. Mini Ferns for Terrariums and Fairy Gardens – Live Plants – 3 Different Plants in 2″ Pots

    Mini Ferns for Terrariums and Fairy Gardens - Live Plants - 3 Different Plants in 2" Pots

    Best for Small Fern Displays

    View on Amazon

    I’d choose this set when a tropical terrarium needs a few compact ferns rather than a broad mix of plant shapes. It supplies three different mini ferns in 2-inch pots, making it easier to place several plants in a small layout than the two-plant Josh’s Frogs 12x12x20 Crested Gecko Vivarium Plant Kit. Fern foliage can add a lush, layered look, while the small pots give you room to arrange plants around hardscape. The tradeoff is uncertainty: the assortment varies seasonally, so buyers cannot select specific varieties. The plants may also need trimming to fit, and this set offers less variety by count than the six-plant Mini Fern Plants set. I’d skip it if exact plant types or a ready-filled larger enclosure are priorities.

    Pros:
    • Includes three different mini ferns for varied foliage
    • Compact 2-inch pots suit small terrariums and fairy gardens
    • Seasonal assortment gives each set some variety
    Cons:
    • Specific fern varieties are not guaranteed
    • Plants may need trimming to fit the finished layout
    • Three plants may not provide enough coverage for a larger enclosure

    Best for: Terrarium keepers who want a small grouping of fern foliage and are comfortable choosing among seasonal varieties.

    Not ideal for: Buyers who need named fern varieties or enough plants to fill a larger enclosure without adding more greenery.

    • Number of plants:3
    • Plant type:Mini ferns
    • Pot size:2 inches
    • Assortment:Seasonally varied; specific plants are not guaranteed
    • Suggested uses:Terrariums, fairy gardens, and outdoor patios
    • Trimming:Can be trimmed to fit the space
    Our verdict
    “Choose this set for a compact fern-focused display if seasonal variety is acceptable and you are willing to trim as needed.”
  2. Josh’s Frogs 12x12x20 Crested Gecko Vivarium Plant Kit

    Josh's Frogs 12x12x20 Crested Gecko Vivarium Plant Kit

    Best for a Matched Vivarium

    View on Amazon

    This kit is the most enclosure-specific choice here: its two plants—one tropical plant and one vine—are intended for a 12x12x20-inch vivarium. That pairing gives buyers more difference in growth habit than either fern-only set, though it offers fewer plants than the six-plant Mini Terrarium Plants assortment. The stated live arrival guarantee applies only when temperatures are between 32°F and 85°F, so delivery conditions matter. For a tropical setup, the vine can add a climbing element while the second plant provides another form of greenery, but two 2.5-inch pots may leave a larger enclosure looking sparse. I’d favor this over the general assorted sets when enclosure dimensions match; I’d choose the LuckyRunes kit instead if a container, soil, tools, and grow light are also needed.

    Pros:
    • Pairs one tropical plant with one vine for different growth forms
    • Designed for a specific 12x12x20-inch vivarium size
    • Includes a live arrival guarantee within the stated temperature range
    Cons:
    • Only two plants may leave a larger enclosure underfilled
    • Guarantee is void outside 32°F to 85°F
    • Does not include a vivarium, soil, or planting tools

    Best for: Keepers furnishing a 12x12x20-inch vivarium who want one tropical plant and one vine with a stated temperature-conditioned arrival guarantee.

    Not ideal for: Buyers with a different-sized enclosure, those seeking a larger plant count, or anyone expecting the guarantee to apply outside its temperature range.

    • Kit contents:1 tropical plant and 1 vine plant
    • Number of plants:2
    • Pot size:2.5 inches
    • Vivarium compatibility:12x12x20 inches
    • Live arrival guarantee:Yes, when temperatures are between 32°F and 85°F
    Our verdict
    “Pick this kit for a 12x12x20-inch vivarium when two complementary plants suit your plan and shipping temperatures fall within the stated range.”
  3. LuckyRunes Premium Terrarium Kit with Live Moss, 24-Piece Glass Set

    LuckyRunes Premium Terrarium Kit with Live Moss, 24-Piece Glass Set

    Best Complete Terrarium Kit

    View on Amazon

    I’d rank this as the most complete starting point for someone who needs the terrarium as well as planting materials. The 24-piece glass set includes live moss, nutrient soil, pebbles, driftwood, tools, a spray bottle, and an adjustable LED grow light. That makes it a different proposition from the plant-only Mini Terrarium Plants set, which gives you six plants but no container or setup materials. The light and included supplies can reduce the number of separate purchases, while the glass container creates a contained display. The tradeoff is that this is centered on live moss and a supplied arrangement, not a larger assortment of tropical plants. Moss also needs regular misting and humidity care, so I’d skip it if you want a low-attention setup or already have a suitable container and lighting.

    Pros:
    • Combines a glass container, live moss, soil, and decorative materials
    • Adjustable LED grow light supports indoor placement
    • Includes planting tools, a spray bottle, and a wooden base
    • Printed care guidance and step-by-step assembly suit beginners
    Cons:
    • Live moss needs regular misting and humidity maintenance
    • The product data does not specify a count of tropical plants beyond the included moss
    • The supplied kit format offers less choice over individual plant varieties

    Best for: Beginners who want a glass terrarium, live moss, basic planting supplies, and adjustable lighting in one set.

    Not ideal for: Plant collectors who mainly want a broad selection of tropical plants, or owners who already have a container and lighting and do not need the included accessories.

    • Pieces included:24
    • Container material:Glass
    • Live moss:Included
    • Soil:Nutrient soil
    • Decorative elements:Pebbles and driftwood
    • Tools and accessories:Planting tools, spray bottle, and wooden base
    • Grow light:Adjustable LED
    Our verdict
    “Choose this all-in-one set if you need a container, moss, supplies, and lighting more than a wide selection of tropical plants.”
  4. Mini Fern Plants – 6 Assorted Varieties in 2″ Pots for Terrariums and Fairy Gardens

    Mini Fern Plants - 6 Assorted Varieties in 2" Pots for Terrariums and Fairy Gardens

    Best Fern Variety Set

    View on Amazon

    For a fern-led tropical display, I’d choose these six assorted mini ferns over the three-plant Mini Ferns for Terrariums set when the design needs more foliage and visual variety. All arrive in 2-inch pots, which keeps the plants compact and ready to arrange without repotting first. Compared with the six-plant Mini Terrarium Plants set, this option narrows the selection to ferns rather than assorted plant types; that can make a layout feel more cohesive, but it limits contrast in leaf shape and growth habit. Small pots need attentive watering, and the listing notes that the plants may need more humidity than a typical room provides. I’d choose another set if you want mixed plant types or do not plan to manage humidity.

    Pros:
    • Six plants provide more coverage than the three-fern set
    • Assorted fern varieties add visual variation within one plant type
    • Compact 2-inch pots suit terrariums and fairy gardens
    • Ready-to-use pots do not require repotting before arranging
    Cons:
    • Small pots require careful watering to avoid overwatering
    • May need higher humidity than a typical household provides
    • Fern-only assortment offers less plant-type contrast than mixed assortments

    Best for: Terrarium builders who want several compact fern varieties for a cohesive, foliage-heavy display.

    Not ideal for: Buyers seeking mixed plant types or a setup that can tolerate typical low-humidity household conditions without extra care.

    • Quantity:6 plants
    • Plant type:Mini ferns
    • Varieties:6 assorted varieties
    • Pot size:2 inches
    • Suggested uses:Terrariums and fairy gardens
    • Humidity:May require higher humidity than typical household conditions
    Our verdict
    “Choose this set when you want six compact ferns for a coordinated, humid terrarium and can manage their watering needs.”
  5. Mini Terrarium Plants, 6 Assorted Plants in 2-Inch Pots

    Mini Terrarium Plants, 6 Assorted Plants in 2-Inch Pots

    Best Mixed Plant Assortment

    View on Amazon

    This is my pick for buyers who want six assorted plants rather than a fern-only arrangement. The listing describes them as suited to high-humidity environments and usable in open or closed terrariums, giving this set broader format flexibility than the Mini Fern Plants set. That flexibility does not mean every plant will suit every layout equally, so I’d check the enclosure conditions against the plants’ needs before settling on an open design. Compared with the three-plant mini fern set, this one gives you twice the plant count and a wider assortment, but the product data does not identify the varieties. Ordering several sets may bring different plants, though duplicates can occur for orders over three sets. I’d skip it if you need named species or a predictable repeat assortment.

    Pros:
    • Six assorted plants provide more variety than the three-fern set
    • Listed for use in both open and closed terrariums
    • High-humidity preference fits many tropical terrarium setups
    Cons:
    • Specific plant varieties are not provided in the product data
    • Orders over three sets may include duplicates
    • The assorted selection may not suit a buyer seeking a coordinated fern-only display

    Best for: Terrarium makers who want a six-plant mixed assortment for a high-humidity display and are flexible about the specific varieties.

    Not ideal for: Buyers who need named plants, a guaranteed unique assortment across multiple sets, or plants selected for a particular enclosure condition.

    • Quantity:6 plants
    • Pot size:2 inches
    • Plant varieties:Assorted
    • Suitable for:Open or closed terrariums
    • Humidity preference:High humidity
    • Multiple-set note:Different varieties may be provided, but duplicates may occur for orders over three sets
    Our verdict
    “Pick this set for a flexible, mixed tropical planting if you value variety over knowing the exact plants in advance.”
  6. Mini Terrarium Plants, 2 Assorted Plants in 2-Inch Pots

    Mini Terrarium Plants, 2 Assorted Plants in 2-Inch Pots

    Best for a Small, Flexible Planting

    View on Amazon

    This two-plant set suits a small tropical planting where space matters more than variety. Its 2-inch pots are easier to fit into a compact terrarium than the 2.5-inch pots in Terrarium & Fairy Garden Plants – 10 Miniature Plants, while the option to grow these plants later as houseplants gives them a use beyond one display. The tradeoff is that the plants are only identified as assorted, so I can’t tell whether the pair will match a particular humidity level, light setup, or visual plan. Compared with the 12x12x18 Tropical Vivarium Plant Kit, this is a simpler, less tank-specific choice with far fewer plants. It makes sense for a small project, but buyers who want a coordinated mix or named varieties should choose a more clearly specified set.

    Pros:
    • Two plants keep a small terrarium planting manageable
    • 2-inch pots suit compact displays
    • Described as suitable for high-humidity terrariums and fairy gardens
    • Plants can also be grown in larger pots as houseplants
    Cons:
    • Specific plant varieties are not identified
    • Only two plants are included, limiting coverage in a larger enclosure
    • The listing provides no detailed care requirements for matching plants to a setup

    Best for: Terrarium owners with limited planting space who want two small plants that can later move into larger houseplant pots

    Not ideal for: Buyers planning a varied or carefully coordinated tropical layout, since the plant varieties are not identified

    • Quantity:2 plants
    • Varieties:Assorted; specific varieties not identified
    • Pot size:2 inches
    • Suitable for:Terrariums, fairy gardens, or larger pots as houseplants
    • Growing environment:High-humidity environments
    • Shipping restriction:Licensed to ship to California
    Our verdict
    “Choose this pair for a compact tropical display when small pots and future houseplant use matter more than knowing the exact varieties.”
  7. Terrarium & Fairy Garden Plants – 10 Miniature Plants in 2.5-inch Pots

    Terrarium & Fairy Garden Plants - 10 Miniature Plants in 2.5-inch Pots

    Best for Filling a Larger Display

    View on Amazon

    For a terrarium that needs several planting points, this 10-plant assortment offers more coverage than the two-plant Mini Terrarium Plants set. The listed mix includes miniature ferns and polka dot plants, giving buyers more guidance about the look than an assortment with unnamed varieties. Its 2.5-inch pots, though, need more room than the 2-inch pots in that smaller set, so this is a better fit for a generously sized terrarium or fairy garden than a tight glass container. Seasonal variation also means the exact selection may change, and the listing gives limited care detail. Compared with Josh’s Frogs’ tank-specific 12x12x18 kit, this set supplies more plants but is less tailored to a particular vivarium footprint.

    Pros:
    • Ten plants provide more planting coverage than the two-plant set
    • Varieties may include miniature ferns and polka dot plants
    • 2.5-inch pots are sized for miniature garden displays
    • Seasonal assortment can offer variety in the selection
    Cons:
    • The seasonal mix may vary, so the exact plants are not guaranteed
    • 2.5-inch pots may be too large for compact terrariums
    • Care requirements are not described in detail

    Best for: Gardeners furnishing a larger terrarium or fairy garden who want multiple miniature plants and a mix that may include ferns and polka dot plants

    Not ideal for: Owners of small terrariums or buyers who need a guaranteed, consistent plant list and detailed care guidance

    • Number of plants:10
    • Pot size:2.5 inches
    • Plant varieties:Miniature ferns and polka dot plants
    • Seasonal variation:Yes; assortment may vary
    • Suitable for:Terrariums and fairy gardens
    • Plant format:Miniature plants
    Our verdict
    “Pick this assortment to fill a roomier terrarium with many small plants, but skip it if exact varieties or compact pot dimensions are priorities.”
  8. Josh’s Frogs 12x12x18 Tropical Vivarium Plant Kit

    Josh's Frogs 12x12x18 Tropical Vivarium Plant Kit

    Best for a Standard 12x12x18 Vivarium

    View on Amazon

    This kit is the most enclosure-specific pick here: its six live plants are selected for a 12x12x18-inch vivarium, with two tropicals, a fern, a vine, and two bromeliads. That makes it a more directed starting point than the seasonal 10-plant assortment, which offers greater quantity but no stated tank dimensions. The mix also gives a layout several plant forms rather than a collection of similar small specimens. There are handling and shipping caveats: bromeliads arrive bare root, and the live-arrival guarantee applies only within the stated 32°F–85°F temperature range. The supplied sun and soil fields may not map neatly to every enclosed tropical setup, so buyers should check plant needs against their lighting and substrate before ordering.

    Pros:
    • Designed for a specific 12x12x18-inch vivarium size
    • Six plants span tropicals, a fern, a vine, and bromeliads
    • Combines several plant forms for a more varied enclosure layout
    • Includes a live-arrival guarantee within the stated temperature range
    Cons:
    • Two bromeliads arrive bare root and need careful handling
    • Live-arrival guarantee is void outside 32°F–85°F
    • The specified tank size limits its fit for other enclosure dimensions

    Best for: Vivarium keepers setting up a 12x12x18-inch enclosure who want a six-plant mix with ferns, a vine, tropicals, and bromeliads

    Not ideal for: Owners of different-sized enclosures or buyers who want every plant delivered potted and without temperature-related shipping conditions

    • Brand:Josh’s Frogs
    • Plant count:6
    • Plant types:2 tropicals, 1 fern, 1 vine, 2 bromeliads
    • Tank size compatibility:12x12x18 inches
    • Pot size:2.25 inches; bromeliads ship bare root
    • Item weight:10.4 ounces
    • Sunlight exposure:Full sun
    • USDA hardiness zone:3
    • Soil type:Sandy soil
    Our verdict
    “Choose this kit for a 12x12x18 tropical vivarium if you want a varied, enclosure-matched plant mix and can handle bare-root bromeliads.”

How We Picked

I ranked these options by how clearly they help a buyer build a tropical terrarium: the usefulness of the plant selection, the fit between the kit and its intended enclosure, the amount of planning left to the buyer, and the flexibility to create different layouts. I also weighed whether a pack’s size and focus make sense for a compact display, a fuller planting, or a particular vivarium.

The two Josh’s Frogs kits rank highest for buyers whose enclosure matches their stated dimensions, because that specificity reduces guesswork when planning a vivarium. The LuckyRunes kit earns a distinct place for shoppers who want glass components and live moss together. Assorted and fern-focused plant packs follow as flexible choices, with their ranking shaped by plant count and specialization rather than a complete enclosure plan. Pack contents alone cannot confirm suitability for every tropical species, so buyers should check the current listing and match care needs to their setup.

Factors to Consider When Choosing Terrariums For Tropical Plants

Choosing plants is only one part of setting up a tropical terrarium. I’d decide on the enclosure, moisture routine, and planting space first; those choices affect whether a small assortment is enough or a coordinated kit is a better fit.

Match the Kit to Your Enclosure Dimensions

Measure the usable interior space, not just the outside of the enclosure, before selecting a kit. Hardscape, drainage layers, and equipment all reduce the room left for roots and foliage. A kit named for a particular vivarium size can help with planning, but it does not mean every included plant will suit every layout. Tall enclosures need plants that can occupy vertical space without crowding the floor, while low displays call for restrained growth. A common mistake is buying a larger assortment before deciding where plants, branches, or hides will go. Sketching the hardscape first can prevent crowded planting and unnecessary extras.

Choose Plants for the Humidity and Airflow You Can Provide

Tropical does not mean every plant wants constant wetness. A closed container can hold humidity, while a vented vivarium may dry more quickly; the same plant selection can respond differently in each setup. Match plant care guidance to your enclosure’s ventilation, light, and watering habits rather than relying on a tropical label alone. Poor airflow and persistently soggy substrate can create problems even for moisture-loving plants. If you are new to enclosed planting, start with a manageable group and observe how quickly the substrate dries. That approach helps you adjust watering before committing to a densely planted display.

Decide Between a Curated Kit and Individual Plant Packs

A coordinated kit can simplify shopping when its stated enclosure size and contents match your plan. Individual plant packs give you more control over the mix, but put the burden of checking compatibility and arranging the layout on you. A glass-and-moss set may be appealing for a decorative project, while a vivarium plant kit is a more direct fit for someone planning around a particular enclosure. Neither format automatically includes everything needed for a healthy planted environment. Check what is actually included, then list any substrate, drainage, lighting, or other components you still need. Paying for a bundle makes sense when its contents serve your design rather than merely increasing the item count.

Use Plant Count as a Layout Clue, Not a Coverage Promise

Pack counts can help compare small starter groups with larger assortments, but they do not tell you how much surface area the plants will cover as they grow. Pot size, plant maturity, growth habit, and the gaps left for hardscape all affect the finished look. A two-plant pack can suit a compact container or a cautious first build; a ten-plant assortment may offer more choices for a larger planting plan. Avoid filling every open patch at the start, since plants need room to grow and the layout can become difficult to maintain. Leave access for pruning and cleaning, especially in a humid enclosure. Think about the mature arrangement, not only how full the container looks on setup day.

Check Plant Identity and Care Details Before Buying

Descriptions such as assorted plants or miniature ferns may not provide the exact species mix you want. If a particular plant’s size, light needs, or care requirements matter, confirm the current listing details before ordering. This is especially relevant when combining different packs: plants that look compatible in a product photo may have different preferences for moisture or light. For animal vivariums, check that every plant is suitable for the animals and husbandry plan, and seek species-specific guidance where needed. Keep plant labels after arrival so you can track growth and care. A little identification work can make ongoing maintenance more predictable.

Frequently Asked Questions

Should I choose a vivarium kit or buy miniature plants separately?

I’d choose a vivarium kit when its stated enclosure dimensions match your setup and you want a more coordinated starting point. Separate plant packs make more sense when you already have a layout in mind, need a particular plant focus, or want to add greenery in stages. Compare the included contents with your actual plan, since a kit may not cover substrate, lighting, or other setup needs. For either route, check current plant details and care requirements before combining species. The better choice is the one that fits your enclosure and reduces the parts you still need to source.

How many plants should I order for a small tropical terrarium?

There is no reliable plant count without knowing the container’s interior dimensions, the plants’ mature size, and how much hardscape you plan to add. The two- and three-plant packs in this roundup can suit a restrained or compact planting, while larger assortments offer more choices for filling a broader layout. More plants do not automatically create a better result; overcrowding can limit growth and make maintenance harder. Leave open space for airflow, access, and future growth. If you are unsure, begin with fewer plants and add more after seeing how the first group fits.

Can I use these plants in a terrarium that houses a reptile or amphibian?

Do not assume a plant pack is suitable for an animal enclosure solely because it is marketed for a vivarium or tropical setup. Confirm the identity of each plant and check its suitability for the species you keep, including any risk from ingestion or contact. Also make sure its light, moisture, and growth needs fit the animal’s habitat conditions. A plant’s care preferences should not override the temperature, ventilation, or humidity requirements of the animal. When the listing does not identify plants clearly, ask the seller or choose plants you can verify before adding them.

Do I need a glass terrarium kit if I already have an enclosure?

No; a glass kit is most useful when you want the container or decorative components it includes. If you already own an enclosure, compare the kit’s plant-related contents with what your setup still needs and avoid paying for pieces that will go unused. The LuckyRunes set offers a different format from the enclosure-specific Josh’s Frogs kits, so its appeal depends on whether its glass components suit your project. Check dimensions and access points before buying any container, since maintenance and planting space matter as much as appearance. For an existing vivarium, a plant-only assortment may be the more direct route.

Are fern-focused packs better for a tropical terrarium than mixed assortments?

Fern-focused packs are a better fit when miniature ferns are central to the look you want, but they are not automatically better for every tropical enclosure. Mixed assortments give you more variety, which can help create contrasting forms, though they require closer attention to differing care needs. Compare the stated plant varieties and match them to your light, humidity, and available space. Avoid choosing by theme alone if you need a specific growth habit or plant size. The right pack is the one whose plants suit both your design and the conditions you can maintain.

Conclusion

Best overall: I’d choose the Josh’s Frogs 12x12x18 Tropical Vivarium Plant Kit when that enclosure size fits your plans, because it gives the clearest starting point for an enclosure-led tropical planting. Best for a taller setup: the 12x12x20 Crested Gecko Vivarium Plant Kit is the more fitting pick when you need the taller stated format. Best for a decorative kit: consider the LuckyRunes 24-piece glass set if its glass components and live moss match your project. Best value in flexibility: the assorted six-plant or ten-plant packs offer a broader plant selection, while the small two- or three-plant packs suit compact builds and gradual planting. Best for beginners: I’d start with a smaller, manageable pack or a dimension-matched vivarium kit, then check plant identities and care needs before adding more. Choose by enclosure fit and maintenance needs first; plant count and presentation come after.
