Best Plants for Closed Terrariums

1. Fittonia (Nerve Plant)

Fittonias are vibrant, low-growing plants with eye-catching veined leaves, making them a striking choice for terrariums. They come in various colors, from green with white veins to pink, red, or purple. Nerve plants thrive in humid conditions and prefer indirect light, making them ideal for a closed environment.

2. Peperomia

Peperomias are small, low-maintenance plants that come in many varieties, such as Peperomia obtusifolia (baby rubber plant) and Peperomia caperata (emerald ripple). Their thick, waxy leaves help retain moisture, making them well-suited for a closed terrarium setup.

3. Ferns

Many types of ferns, such as maidenhair fern, button fern, and lemon button fern, do exceptionally well in the high humidity of closed terrariums. These delicate plants enjoy constant moisture and shaded conditions, which a terrarium environment can easily provide.

4. Mosses

Moss is a must-have for closed terrariums. It adds a lush, green carpet-like layer that enhances the visual appeal while also helping maintain humidity levels. Java moss and sheet moss are popular choices, as they are easy to care for and provide excellent ground cover.

5. Pilea

Pilea species, such as Pilea depressa (baby tears) and Pilea glauca (silver sprinkles), offer a lovely cascading effect in a terrarium. These small-leaved, trailing plants add texture and are perfect for filling in the nooks and crannies of your setup.

6. Miniature Orchids

For an elegant touch, consider adding a miniature orchid to your closed terrarium. Varieties like the Lepanthes or Masdevallia thrive in high-humidity environments and will add a splash of exotic beauty.

7. Bromeliads

Small bromeliads, like the Neoregelia species, bring a burst of color to any terrarium. These tropical plants are adapted to humid environments and can add a pop of brightness with their stunning, rosette-shaped foliage.

8. Begonias

Rex begonias and miniature begonia varieties are fantastic for adding a splash of texture and color. Their dramatic foliage comes in various patterns and hues, making them a focal point in your terrarium.

9. Ficus Pumila (Creeping Fig)

Creeping fig is a fast-growing vining plant that creates a lovely cascading effect in a terrarium. Its tiny leaves and vigorous growth habit make it ideal for covering hardscapes or creeping along the walls of your glass container.

10. Anthurium

Anthuriums are another fantastic option for closed terrariums, particularly the dwarf varieties. Their glossy leaves and vibrant blooms (in shades of red, pink, or white) can elevate the look of your terrarium with a tropical flair.

Tips for a Successful Closed Terrarium

• Lighting: Closed terrariums thrive in indirect light. Avoid direct sunlight, as it can overheat and damage the plants.
• Moisture Levels: Keep an eye on moisture to prevent mold growth. If condensation becomes excessive, open the lid for a short time to let it air out.
• Substrate Layers: A well-drained base with pebbles, activated charcoal, and potting soil will ensure a healthy environment.

Closed terrariums are rewarding projects that require minimal maintenance but offer maximum impact. By choosing the best plants for closed terrariums that love high humidity and filtered light, you’ll have a lush, miniature world that practically takes care of itself.
