What is a Closed Terrarium?

A closed terrarium is a self-contained ecosystem housed within a glass container. It mimics the natural water cycle, creating a humid environment that allows plants to thrive. The glass enclosure keeps moisture trapped, resulting in a low-maintenance and visually stunning mini garden.

Choosing the Right Plants

Not all plants are suitable for closed terrariums. It’s crucial to select species that can tolerate high humidity and low light conditions. Here are some of the best plants to consider:

1. Fittonia (Nerve Plant)

Fittonia, also known as the nerve plant, is a popular choice for closed terrariums. With its vibrant red, pink, or white veins on dark green leaves, it adds a pop of color to your indoor garden. It thrives in high humidity and low to medium light conditions.

2. Pilea (Chinese Money Plant)

The Pilea, commonly known as the Chinese Money Plant, is a trendy houseplant that adapts well to closed terrariums. Its round, coin-shaped leaves and compact size make it an excellent choice for limited spaces. It prefers indirect light and high humidity.

3. Selaginella (Spikemoss)

Selaginella, also known as spikemoss, is a unique plant that adds texture and interest to closed terrariums. Its feathery, fern-like foliage creates a lush, forest-like ambiance. Selaginella thrives in high humidity and prefers bright, indirect light.

4. Peperomia

Peperomia is a versatile plant that comes in various leaf shapes, colors, and textures. Its compact size and low light requirements make it an ideal choice for closed terrariums. Peperomia is also known for its air-purifying qualities.

5. Ferns

Ferns, such as the Maidenhair Fern or Bird’s Nest Fern, are classic choices for closed terrariums. Their delicate fronds and graceful appearance add a touch of elegance to any indoor garden. Ferns thrive in high humidity and indirect light.

Tips for Maintaining Closed Terrariums

Keeping a closed terrarium healthy and thriving requires some care and attention. Here are a few tips to help you maintain your mini ecosystem:

1. Place in Indirect Light

While closed terrariums don’t require direct sunlight, they still need some light to thrive. Place your terrarium in an area with indirect light, such as near a window with sheer curtains.

2. Avoid Overwatering

Overwatering is one of the most common mistakes in closed terrarium care. The enclosed environment retains moisture, so it’s important to water sparingly. Check the soil moisture level before watering and only water when it feels dry.

3. Prune and Maintain

Regular pruning helps control the growth of plants inside the terrarium. This prevents overcrowding and ensures proper air circulation. Remove any yellow or wilted leaves to keep the ecosystem healthy.


Closed terrariums offer a unique and low-maintenance way to bring nature indoors. By selecting the right plants and following proper care techniques, you can create a beautiful and thriving miniature ecosystem. With the best plants for closed terrariums in 2023 and the tips provided, you’ll be well on your way to enjoying the beauty of these self-sustaining mini gardens.
