For most mixed terrariums, I’d start with Terrarium and Fairy Garden Plants, 10 Plants in 2.5-Inch Pots: its larger assortment offers the most flexibility for filling a roomy display. The six-mini-fern pack is a better match for fern-focused designs, while the Live Moss Duo Pack suits buyers who want ground cover rather than a collection of potted plants. The main tradeoffs are plant variety and count versus container space, and whether you need foliage plants, moss, or both. I compare all six options by format, planting flexibility, and likely fit for different terrarium plans below.

Key Takeaways
- The 10-plant assortment offers the widest planting flexibility, but its 2.5-inch pots may be too large for compact terrariums.
- The six-fern pack leads among fern-focused options; the three-fern pack is a smaller commitment for a limited planting area.
- Moss packs serve a different purpose from potted assortments: they add ground cover and texture but do not provide the same range of upright plants.
- The Optiflora two-plant set prioritizes a small footprint, making it a plausible fit for a compact build, though it supplies fewer plants than the larger assortments.
- Product count alone does not determine fit: pot diameter, available headroom, and the terrarium’s moisture and airflow conditions all affect what can thrive.

Mini Fern Plants (6 Plants) (2″ Pots) Terrariums | Fairy Gardens | Assorted Varieties
For buyers who want several leafy plants to shape a small indoor scene, Optiflora’s six mini ferns offer more planting flexibility than the three-plant Hirt’s Gardens assortment. Each arrives in a 2-inch pot, a compact starting size for terrariums and fairy gardens, while the mix of fern types adds variation without requiring a specific cultivar choice. Their partial-shade preference and moderate watering needs suit indoor setups better than the full-sun listing for Optiflora’s two assorted mini plants. The tradeoff is that six plants take more room than a small container may have, and these are not a fit for bright, exposed locations. Expect to move them into larger pots as they grow; the supplied pots are a starting point, not a permanent home.
Pros:- Six plants provide more layout options than the three-fern Hirt’s Gardens assortment.
- 2-inch pots make the plants easier to position in compact scenes.
- Assorted fern types add variation in foliage.
- Partial shade and moderate watering suit many indoor growing spaces.
Cons:- Six plants may exceed the capacity of a small terrarium.
- The small pots may need replacement as the ferns grow.
- Partial-shade requirements limit placement in sunny displays.
Best for: Indoor terrarium and fairy-garden builders who want several small ferns and room to arrange a varied planting.
Not ideal for: People with a tiny enclosure or a bright, full-sun display area; six plants may crowd the former, while partial-shade conditions suit the latter poorly.
- Plant count:6
- Pot size:2 inches
- Plant type:Assorted mini ferns
- Indoor/outdoor usage:Indoor
- Sunlight exposure:Partial shade
- Soil type:Peat soil
- Moisture needs:Moderate watering
- Expected foliage period:Year round
- Brand:Optiflora
Our verdict“Choose this set if you want a flexible group of small, shade-suited ferns and have room to accommodate six plants.”
Live Moss Duo Pack – Two Types of Real Live Sheet/Sphagnum Moss for Terrariums and Reptile Habitats
This duo is the foliage-free choice for builders who want a living forest-floor layer rather than upright plants. Two contrasting moss types add surface texture, and the listing describes support for humidity—a useful fit for vivariums and other moist terrarium setups. Compared with the LuckyRunes Live Moss 4-Pack, this set supplies fewer pieces, but its stated revival time after misting gives buyers a clear first step after delivery. It arrives dry, so it needs rehydration and regular moisture; it is not a set-and-forget ground cover. The pieces are also relatively small at about 3.5 by 7 inches each, which may leave a larger enclosure only partly covered. Choose it for a focused patch or a smaller habitat, not for an instant, full-floor moss carpet.
Pros:- Two contrasting moss types create texture at ground level.
- Live moss can contribute to a humid habitat.
- Each piece measures approximately 3.5 by 7 inches.
- The moss is described as reviving within an hour after misting.
Cons:- Arrives dry and needs misting to revive.
- Requires regular moisture and suitable conditions to keep growing.
- Two pieces may not cover a larger terrarium floor.
Best for: Terrarium and reptile-habitat keepers who want two live moss textures for a smaller, humidity-managed area.
Not ideal for: Buyers seeking upright plants, a ready-to-use carpet, or ground cover for a large enclosure without adding more moss.
- Package quantity:2 pieces
- Piece size:Approximately 3.5 × 7 inches
- Expected plant height:1 inch
- Sunlight exposure:Full shade
- Moisture needs:Regular watering; mist regularly
- Indoor/outdoor usage:Indoor and outdoor
- Humidity support:Yes
- Growth:Grows over time under proper conditions
- Unused shelf life:Up to 2 months
Our verdict“Pick this duo for a small, humid habitat where living ground cover matters more than upright greenery.”
Mini Fern Assortment for Terrariums and Fairy Gardens, 3 Live Plants in 2-Inch Pots
Three ferns make this assortment a middle ground between Optiflora’s six-plant fern set and its two-plant assorted set: enough greenery for a small arrangement, with fewer plants to place and maintain. The 2-inch pots suit compact displays, and the listing says the ferns can be trimmed, which gives buyers a way to manage growth in a confined scene. Its partial-sun specification differs from the six-fern Optiflora set’s partial-shade guidance, so the two are not interchangeable for every location. The main uncertainty is variety: types change by season, and measurements are approximate, making this a poor match for anyone planning around a particular fern or exact dimensions. It can also grow in standard pots, but its strongest role here is a modest terrarium or fairy-garden grouping.
Pros:- Three plants offer a manageable grouping for a compact display.
- 2-inch pots suit small terrarium and fairy-garden layouts.
- Plants can be trimmed as needed.
- Can also be grown in standard pots.
Cons:- Fern varieties vary by season and are not guaranteed.
- Measurements are approximate, which can complicate precise layouts.
- Partial-sun guidance may not suit deeply shaded terrariums.
Best for: Buyers creating a small fern-centered terrarium who want fewer plants than a six-piece set and are flexible about varieties.
Not ideal for: Collectors who need named fern varieties or growers whose display has only deep shade.
- Plant count:3
- Pot size:2 inches
- Plant type:Mini ferns; varieties vary by season
- Sunlight exposure:Partial sun
- Color:Green
- Item weight:2.1 pounds
- Brand:Hirt’s Gardens
- Care feature:Can be trimmed as needed
Our verdict“Choose this assortment for a small, trim-friendly fern display if exact varieties and dimensions are not priorities.”
LuckyRunes Live Moss 4-Pack for Terrariums, Potted Plants & Floral Decor
When the aim is broad ground coverage rather than a few accent patches, the LuckyRunes four-piece pack offers twice as many pieces as the Live Moss Duo Pack, with each measuring about 3.5 by 7 inches. Its mix of moss varieties can bring more texture to closed terrariums, bonsai top dressing, or miniature landscapes, and the listing describes the material as dye-free and non-toxic. Unlike the duo pack, this listing names several possible moss types, though it also allows similar varieties, so the exact mix is not certain. It arrives dry and needs misting, followed by moderate-to-high humidity and indirect light. That care burden makes it less suitable for dry displays or buyers who want a low-attention plant; extra pieces do not remove the need to maintain moisture.
Pros:- Four pieces provide more coverage than the two-piece Live Moss Duo Pack.
- Mixed varieties add natural differences in texture.
- Dye-free, non-toxic material suits decorative and habitat projects.
- Suitable for closed terrariums, bonsai top dressing, and miniature landscapes.
Cons:- Arrives dry and needs time and misting to rehydrate.
- Needs moderate-to-high humidity and indirect light.
- The exact variety mix may differ from the listed examples.
Best for: Terrarium makers who need more live moss coverage for a humid, indirectly lit scene or several small projects.
Not ideal for: People with dry or sunny enclosures, or anyone unwilling to rehydrate and maintain moss regularly.
- Package quantity:4 pieces
- Piece size:Approximately 3.5 × 7 inches
- Varieties:Hypnum, Dicranum, Brachythecium, Racomitrium, or similar
- Sunlight exposure:Full shade; indirect light
- USDA hardiness zone:3 to 9
- Expected plant height:1 inch
- Soil type:Peat
- Moisture needs:Moderate to high
- Material:Live, natural, sustainable, non-toxic moss
Our verdict“Choose this pack over the two-piece moss duo when you need more ground coverage and can maintain a humid, shaded setup.”
Optiflora Mini Terrarium Plants, 2 Assorted Plants in 2-Inch Pots
This is the smallest upright-plant set in the lineup: two assorted plants in 2-inch pots give a compact project some greenery without the six-plant commitment of Optiflora’s mini fern set. Unlike the moss packs, these are plants for buyers who want distinct upright forms rather than a ground layer. The product is described as suitable for terrariums and fairy gardens, but its listed full-sun exposure and sandy soil make it a less straightforward match for a humid, shaded terrarium than either fern assortment. The plant varieties are not specified, so buyers cannot plan around a particular look or care profile. Moderate watering is listed, and the plants can also grow in larger pots, but the mixed and unspecified assortment calls for flexibility.
Pros:- Two plants fit a small project better than the six-fern Optiflora set.
- 2-inch pots are convenient for compact arrangements.
- Can be used in terrariums, fairy gardens, or larger pots.
- Assorted plants provide some variety in a small set.
Cons:- Specific plant varieties are not guaranteed.
- Full-sun guidance may conflict with shaded terrarium conditions.
- The listed sandy-soil preference may require a different setup from peat-rooted fern options.
Best for: Buyers making a small terrarium or fairy garden who want just two upright plants and can provide a bright, full-sun location.
Not ideal for: People building a shaded, closed terrarium or anyone who needs guaranteed plant varieties and specific care requirements.
- Plant quantity:2
- Pot size:2 inches
- Varieties:Assorted; specific plants not guaranteed
- Plant type:Mini terrarium plants
- Sunlight exposure:Full sun
- Soil type:Sandy soil
- Moisture needs:Moderate watering
- Expected blooming period:Winter
- Brand:Optiflora
Our verdict“Pick this pair for a bright, compact planting if you are comfortable choosing without knowing the exact varieties.”
Terrarium and Fairy Garden Plants, 10 Plants in 2.5-Inch Pots
Ten miniature plants make this assortment the broadest planting option among the live-plant picks here: the Mini Fern Assortment includes three plants, while this set can bring more kinds of foliage into one terrarium or fairy garden. The listed examples include ferns and polka dot plants, offering more visual variety than a fern-focused set. The tradeoff is predictability: seasonal availability can change both the varieties and plant sizes, so it suits buyers who welcome an assortment rather than need a specific layout. Each plant arrives in a 2.5-inch pot, larger than the 2-inch pots listed for the Optiflora Mini Terrarium Plants, which may mean more substantial starting plants but also calls for checking the enclosure’s available space. Its care details list full sun to partial shade and moderate watering; match those needs to your terrarium conditions before planting.
Pros:- Includes 10 miniature plants for filling out a planting
- May include both ferns and polka dot plants for varied foliage
- Suitable for terrariums and fairy gardens
- 2.5-inch pots provide a larger starting size than the 2-inch pots listed for some alternatives
Cons:- Plant varieties can change by season, so the exact mix is uncertain
- Plant sizes may vary, making a uniform layout harder to plan
- The larger listed pot size may not fit compact terrariums without adjustment
Best for: Terrarium and fairy-garden builders who want a varied live planting with more plants than the smaller assortments provide.
Not ideal for: Buyers planning a precise species mix or a very small enclosure, since seasonal substitutions and 2.5-inch pots can limit predictability and fit.
- Quantity:10 plants
- Pot size:2.5 inches
- Example varieties:May include miniature ferns and polka dot plants
- Sunlight exposure:Full sun, partial shade
- USDA hardiness zone:3
- Soil type:Sandy soil
- Watering needs:Moderate
- Brand:JM BAMBOO
Our verdict“Choose this assortment if you want the most plants and can accept seasonal variation; choose a smaller, more focused set if you need a predictable mix or have limited space.”
How We Picked
I ranked these options by how clearly their format and quantity match common terrarium plans: a mixed planting, a fern-centered design, a compact build, or a moss-led landscape. I gave more weight to flexibility and useful planting coverage than to raw item count, since six or ten plants can be a poor fit if a container cannot accommodate their pot sizes or growth habits. The listed formats and quantities also shaped the comparisons: potted plants are not interchangeable with sheet or sphagnum moss.
The 10-plant assortment ranks first for buyers with room to arrange a varied display; the six-fern set follows for a more focused but still generous planting. Smaller plant sets rank lower on breadth but may suit constrained layouts, while the moss products rank according to their ground-cover role rather than as substitutes for potted greenery. Product details provided do not specify exact species, mature dimensions, or growing conditions, so I avoid treating assortment names as guarantees of plant identity or long-term suitability.

Factors to Consider When Choosing Terrarium Plants
Choosing terrarium plants starts with the container and growing conditions, not the number of plants in a listing. These factors can help you avoid crowding, incompatible moisture needs, and purchases that do not match the look you want.
Match Plant Size to the Finished Layout
Compare pot diameter with the usable floor area, then leave space for plants to grow rather than planning only for their arrival size. A 2.5-inch pot can occupy much of a small vessel, while several 2-inch pots may still crowd a narrow opening. Measure the interior, not just the outside of the container, and account for hardscape such as rocks or wood. Avoid choosing a large assortment simply because it has more plants; unused extras can be harder to place than a smaller, well-matched set. For a miniature build, favor fewer plants and add ground cover selectively.
Choose Between Upright Plants and Ground Cover
Potted foliage and moss solve different design problems. Fern assortments and mixed plant sets provide height and distinct focal points, while moss softens bare substrate and helps create a continuous, natural-looking floor. If you want a layered composition, decide where height is needed before filling the whole surface with moss. Moss-only packs may leave a display looking flat if you expect upright foliage, while a plant-only set can leave visible gaps around the roots. Combining formats can work, but only when the container has room for both.
Check Moisture and Airflow Compatibility
A closed, humid terrarium and an open container do not offer the same growing conditions. Before buying, look for species-level care details and match them to the amount of airflow, light, and moisture your setup can provide. Broad labels such as “mini fern” or “assorted plants” do not tell you every plant’s needs, so ask the seller for identification when care requirements are unclear. Overwatering a closed vessel can encourage rot, while a dry, open arrangement may not suit plants that need sustained humidity. If the exact contents are unspecified, plan a setup that lets you adjust ventilation and watering rather than assuming all plants have identical needs.
Treat Assortment Count as a Starting Point
Listed counts describe what arrives, not how many plants your terrarium can comfortably hold. A six-plant package may be useful for several small containers or a larger display, while a two-plant set may be enough for a focal arrangement. Check whether the count refers to individual potted plants, moss types, or packages; those units are not directly comparable. Also consider whether you have another use for extras, such as a second container or a garden project. Buying more than your layout can support may lead to crowding and make routine pruning harder.
Ask for Species and Condition Details
Assorted listings can vary in exactly the information a careful buyer needs: plant names, mature size, and care instructions. Request those details when they are not shown, especially if you have a very small enclosure or a specific humidity level in mind. Live plants may also need time to adjust after shipping, so inspect them on arrival and remove damaged foliage before planting. Avoid burying crowns or packing roots tightly into wet substrate; both choices can cause problems even with suitable plants. Clear identification is more useful than a broad promise of variety when long-term care is the priority.
Frequently Asked Questions
Should I choose a potted plant assortment or a moss pack?
Choose potted plants if you want distinct foliage, vertical shape, or focal points. A moss pack is better when your main goal is covering substrate, adding texture, or softening the base of a display. They are not equivalent formats, so compare them by the role each will play rather than by package count. If you want both height and a continuous ground layer, you may need to combine the formats, provided your container has enough room. Check care requirements before mixing them in a sealed setup.
Is the 10-plant set a good choice for a small terrarium?
Not automatically: its 2.5-inch pots can take up substantial space in a compact vessel. Measure the planting area and consider how much room must remain for substrate, drainage materials, and decor. A smaller set such as the two-plant or three-plant option may be easier to arrange without crowding. The larger assortment makes more sense if you are planting a broad container or dividing plants among multiple displays. Leave room for growth rather than filling every open patch on planting day.
How can I choose between the six-fern and three-fern assortments?
Start with the space you have and how many fern groupings you want, not just the number in each package. The six-plant set gives more material for a larger fern-focused scene or multiple small projects, while the three-plant set can suit a contained arrangement. The available listing details do not establish exact species or mature sizes, so ask for those before committing to a tight enclosure. Ferns with different care needs may not behave alike even when sold together. Either set can be a poor fit if the container’s light and humidity do not suit its plants.
Can I put live moss and potted plants in the same terrarium?
Yes, if the plants’ moisture and light preferences overlap and the layout leaves room for both. Use potted plants for height and place moss where it can cover open substrate without smothering plant crowns. A closed terrarium can hold excess moisture, so monitor condensation and increase airflow if the interior stays constantly wet. In an open container, moss may need closer attention to drying than plants with different water needs. Because the moss listings do not identify every species in the supplied information, confirm care guidance before combining products.
What should I ask before ordering an assorted live-plant pack?
Ask for the plant names, approximate delivered size, mature size, and care requirements for each variety. Find out whether the listed pot measurement is the pot diameter and whether the plants are suitable for closed or open terrariums. You can also ask how the plants are packaged and what steps to take if they arrive damaged. These details matter more than a broad assortment label when your container has strict space or humidity limits. If the seller cannot identify the plants, choose a setup that allows you to adjust conditions and avoid mixing them with species that need sharply different care.
Conclusion
Best overall: I’d choose Terrarium and Fairy Garden Plants, 10 Plants in 2.5-Inch Pots for a roomy display where a varied planting is the goal. Best for fern-focused designs: the six-mini-fern pack offers more planting material than the three-plant version. Best for beginners with a small layout: the Optiflora two-plant set keeps the initial planting modest, though buyers should confirm the varieties and care needs. Best value by planting quantity: the six-fern assortment gives more potted plants than the smaller fern and Optiflora sets, if your space can accommodate them. Best for specific needs: choose the Live Moss Duo Pack for two moss types or LuckyRunes Live Moss 4-Pack when you want a multi-pack moss option. Match the format to your container and check species-level care details before planting.
