Key Takeaways
The best terrarium plants for beginners are small, slow-growing, and matched to the right container type. Closed terrariums need humidity-loving plants, while open terrariums need plants that prefer airflow and drier conditions.
- Closed terrariums: moss, fittonia, ferns, peperomia, and baby tears.
- Open terrariums: succulents, cacti, haworthia, echeveria, and air plants.
- Beginner rule: do not mix high-humidity plants with dry-loving succulents in the same closed container.
- Lowest maintenance: preserved moss and preserved flower terrariums need no watering.
How to Choose Terrarium Plants
Start by choosing the container first. If your terrarium is closed or has a lid, choose plants that like humidity. If your terrarium is open, choose plants that prefer airflow and less moisture.
Good terrarium plants should stay compact, tolerate indoor light, and not outgrow the glass container too quickly. Avoid plants with aggressive roots or fast vertical growth unless you plan to prune often.
Best Plants for Closed Terrariums
Closed terrariums create a humid microclimate. These plants usually perform best:
- Moss: ideal for soft green ground cover and moisture-loving setups.
- Fittonia: also called nerve plant; adds colorful leaf veins.
- Button fern: compact and suitable for humid glass containers.
- Maidenhair fern: delicate and beautiful but needs consistent moisture.
- Peperomia: many compact varieties work well in small containers.
- Baby tears: creates a lush carpet effect in humid terrariums.
Best Plants for Open Terrariums
Open terrariums allow more airflow and dry out faster. Choose plants that prefer less humidity:
- Haworthia: compact, sculptural, and beginner friendly.
- Echeveria: attractive rosettes for bright open displays.
- Small cacti: best for dry, sunny open containers.
- Air plants: do not need soil and can be styled with stones or driftwood.
- String of pearls cuttings: useful for trailing texture if the container is open and bright.
Low-Maintenance Preserved Option
If you love the look of terrarium plants but do not want to manage watering, pruning, or light requirements, a preserved terrarium is a better fit. Preserved moss and flowers keep the garden look without needing plant care.
For a ready-made display, see the Handmade Eternal Garden Cube - Spring Meadow. It gives the look of a glass garden with preserved moss and flowers, making it easy to style on a shelf, desk, or gift table.
Terrarium Plant Care Tips
- Place terrariums in bright, indirect light.
- Avoid direct hot sun, which can overheat glass containers.
- Water closed terrariums sparingly; condensation is a clue that moisture is present.
- Open terrariums need more frequent moisture checks.
- Remove yellow leaves quickly to prevent mold.
- Prune plants before they touch the glass too heavily.

Can I mix succulents and moss?
It is usually better not to mix them in a closed terrarium because moss likes moisture and succulents prefer dry conditions.
What is the easiest terrarium option?
A preserved terrarium such as Handmade Eternal Garden Cube - Purple Twilight is one of the easiest options because it does not need watering.
Conclusion
The best terrarium plants depend on the container. Choose moss, ferns, and fittonia for closed humid displays; choose succulents, cacti, and air plants for open dry displays. If you want the look without maintenance, choose a preserved moss and flower terrarium instead.
