Top 10 Easy-Care Plants for Terrariums

Terrariums are miniature gardens enclosed within glass containers that bring a touch of nature indoors. They provide a unique way to enjoy greenery year-round, even in small spaces. One of the most rewarding aspects of terrarium gardening is selecting plants that thrive in the enclosed environment with minimal maintenance. Whether you are a beginner or an experienced gardener looking for low-maintenance options, choosing easy-care plants ensures your terrarium remains lush and vibrant without requiring constant attention.

In this article, we will explore the top 10 easy-care plants perfect for terrariums. These plants are resilient, low maintenance, and well-suited for the humid, controlled environment typical of terrariums.

What Makes a Plant Easy-Care for Terrariums?

Before diving into the list, it’s important to understand what characteristics make a plant easy to care for in a terrarium:

Tolerance to humidity: Terrariums often have high humidity levels, so plants that thrive in moist air are ideal.
Slow growth: Fast-growing plants can quickly overcrowd the limited space inside a terrarium.
Compact size: Small or dwarf varieties help maintain proportion and prevent overcrowding.
Low light tolerance: Many terrariums are placed indoors away from direct sunlight; shade-tolerant plants adapt better.
Minimal watering needs: Plants that don’t require frequent watering reduce maintenance efforts.

With these traits in mind, here are ten plants that fit perfectly into easy-care terrarium gardens.

1. Fittonia (Nerve Plant)

Fittonia is renowned for its striking veined leaves which come in shades of pink, white, or red on green foliage. This tropical plant thrives in warm, humid conditions making it a natural fit for terrariums.

Care Tips: Keep soil consistently moist but not waterlogged. Indirect light is best; avoid direct sun which can scorch the leaves.
Growth Habit: Low-growing and mat-forming, it fills space nicely without overtaking other plants.
Why It’s Easy: Its natural affinity for humidity and compact size make it easy to maintain inside a terrarium.

2. Peperomia

Peperomia species are small tropical plants with thick, fleshy leaves that store water internally. They come in various leaf shapes and colors including green, variegated, and even purple hues.

Care Tips: Prefers bright indirect light but tolerates moderate shade. Water when the top inch of soil dries out.
Growth Habit: Compact and slow-growing; ideal for tight spaces.
Why It’s Easy: Their succulent-like leaves reduce watering frequency and tolerate low light well.

3. Pilea (Aluminum Plant)

The Pilea genus includes several excellent terrarium choices like Pilea cadierei (Aluminum Plant), known for silvery blotches on its leaves. It thrives in humid environments and brings a unique texture with its metallic shine.

Care Tips: Prefers medium indirect light and regular watering to keep soil moist but not soggy.
Growth Habit: Upright but compact habit works well with other plants.
Why It’s Easy: Its adaptability to variable light and humidity levels makes it forgiving for beginners.

4. Selaginella (Spikemoss)

Selaginella is often called spikemoss or clubmoss and resembles miniature ferns. It enjoys high humidity and consistent moisture, making it perfectly suited to enclosed terrariums.

Care Tips: Keep soil damp at all times and place in bright indirect light or partial shade.
Growth Habit: Forms moss-like mats or cushions that spread slowly.
Why It’s Easy: Thrives in humid atmospheres with minimal fuss and adds soft texture.

5. Baby Tears (Soleirolia soleirolii)

Baby Tears produces tiny, delicate round leaves on creeping stems perfect as ground cover inside terrariums. Its lush look adds contrast against larger-leafed plants.

Care Tips: Likes consistently moist soil and indirect bright light.
Growth Habit: Rapidly spreading mat-former but stays low to the ground.
Why It’s Easy: Tolerates varying light conditions and loves moisture-rich environments.

6. Air Plants (Tillandsia)

Air plants absorb moisture and nutrients through their leaves rather than roots, making them very versatile for terrariums without soil beds. They add an exotic look with their spiky forms.

Care Tips: Mist regularly or soak briefly once a week; they need bright, indirect light.
Growth Habit: Small rosettes that can be tucked into nooks or attached to decorative items inside the terrarium.
Why It’s Easy: No soil needed and simple watering routine makes them extremely low maintenance.

7. Mosses

Various moss types such as cushion moss or sheet moss thrive in the humid microclimate of terrariums. Mosses provide a lush green carpet effect covering soil or rocks beautifully.

Care Tips: Keep surface moist with misting; indirect light preferred.
Growth Habit: Spreads evenly forming dense mats.
Why It’s Easy: Moss requires little care beyond moisture maintenance and enhances ecosystem balance inside the container.

8. Miniature Ferns

Small fern varieties like Button Fern (Pellaea rotundifolia) or Maidenhair Fern (Adiantum spp.) do well in humid, shaded conditions typical of terrariums.

Care Tips: Require consistently moist soil and indirect light; avoid dry air drafts.
Growth Habit: Compact fronds add texture without overwhelming space.
Why It’s Easy: These ferns appreciate humidity and offer graceful foliage with minimal intervention.

9. Cryptanthus (Earth Star)

Cryptanthus plants have star-shaped rosettes with colorful striped leaves ranging from green to deep red tones. They prefer high humidity environments similar to most terrariums.

Care Tips: Bright indirect light with moist but well-draining substrate; avoid overwatering roots.
Growth Habit: Low-growing rosettes perfect as focal points or fillers.
Why It’s Easy: Tolerates variable conditions well while providing striking color contrast.

10. Creeping Fig (Ficus pumila)

Creeping Fig is a vine-like plant that clings to surfaces with small leaves perfect for vertical growth inside larger terrariums creating natural green walls.

Care Tips: Likes bright indirect light and regular watering allowing soil to dry slightly between watering.
Growth Habit: Fast-growing but manageable by pruning; great for coverage.
Why It’s Easy: Adapts easily to humid environments and indoor conditions with little fuss needed to keep healthy.

Tips for Creating a Thriving Easy-Care Terrarium

To maximize success with your easy-care plants:

Choose an appropriate container – Glass jars with lids hold humidity better for tropical plants; open containers suit drier species like air plants.
Use proper substrate layers – Start with drainage materials like pebbles or activated charcoal below potting mix to prevent root rot.
Monitor moisture carefully – Overwatering is the primary cause of problems; ensure balanced watering according to plant needs.
Provide adequate lighting – Most easy-care terrarium plants prefer bright indirect sunlight or fluorescent grow lights if natural light is insufficient.
Prune regularly – Keep plants trimmed to prevent overcrowding which can cause mold or pests issues inside the enclosed space.
Maintain humidity – Mist periodically depending on plant type but avoid water pooling on leaves which can lead to fungal diseases.
