Optimal Enclosed Terrarium Plant: The Rapidly Growing Fittonia

Enclosed terrariums create a captivating display of nature's splendor in a compact, controlled setting. These self-contained ecosystems capture the imagination and allow for the observation of natural processes on a miniature scale. Among the variety of plants suited for the unique conditions of an enclosed terrarium, the Fittonia, also known as the Nerve Plant, is particularly noteworthy for its fast growth rate and vibrant appearance. This article will guide you through the benefits of choosing Fittonia for your enclosed terrarium and offer advice on how to cultivate a flourishing miniature garden with this colourful plant.

Fittonia's Success in Enclosed Terrariums

With its vividly veined, lush leaves, Fittonia brings a touch of the exotic to any terrarium. Its compatibility with the enclosed terrarium environment can be attributed to several key factors:

  1. Humidity Lover: Originating from the tropical rainforests of South America, Fittonia thrives in the consistently high humidity found within enclosed terrariums.
  2. Adaptable to Low Light: The plant's natural habitat under the forest canopy has adapted it to prosper in low to medium light, making it an ideal resident for the indirect sunlight conditions typical of enclosed terrariums.
  3. Quick Growth: Fittonia's ability to grow quickly and fill space with its striking foliage ensures that your terrarium becomes a lush, green haven in no time.

How to Plant Fittonia in Your Enclosed Terrarium

  1. Terrarium Selection: Opt for a glass container that can be fully enclosed to maintain the necessary humidity levels for your Fittonia. Ensure it is spacious enough to accommodate the plant’s growth.
  2. Layering: Begin with a drainage layer of stones or pebbles at the bottom, add a layer of activated charcoal to keep the water fresh, and top with a well-draining, moist soil suitable for Fittonia.
  3. Planting: Carefully place your Fittonia in the terrarium, making sure its leaves do not touch the glass to prevent potential rot from excessive moisture.
  4. Light Requirements: Locate a spot for your terrarium where it will receive bright, but indirect sunlight. Direct exposure can lead to overheating and harm the delicate foliage of the Fittonia.
  5. Watering Considerations: Water sparingly at first, as the enclosed nature of the terrarium will help retain moisture, creating a self-sustaining humid environment that reduces the need for frequent watering.

Ensuring Fittonia Thrives

  • Pruning: Regular trimming will keep the Fittonia’s growth in check and encourage a fuller, more aesthetically pleasing plant.
  • Pest Checks: Keep an eye out for pests, which are less common in enclosed terrariums but can still occur. Early detection and treatment are key to maintaining plant health.
  • Propagation: Fittonia can be easily propagated through cuttings, allowing you to expand your terrarium ecosystem or share with other plant enthusiasts.


Fittonia stands out as a premier choice for those looking to add a fast-growing, visually striking plant to their enclosed terrarium. Its love for humidity, ability to thrive in lower light levels, and the visual appeal of its foliage make it not just a plant, but a standout feature of any miniature garden. By adhering to the cultivation tips provided above, you can ensure your Fittonia not only survives but thrives, adding a lush, vibrant component to your enclosed terrarium environment.
