Closed terrariums are like little ecosystems that bring a touch of nature into your home. These self-contained gardens not only look stunning but are also low maintenance, making them an ideal choice for anyone—whether you have a green thumb or not. Choosing the right plants is essential to creating a thriving closed terrarium. Here are ten plants that are perfectly suited for these miniature jungles, along with some helpful tips and additional resources for your terrarium journey.
What Makes a Plant Perfect for a Closed Terrarium?
Closed terrariums create a humid, warm environment due to their sealed design. Plants that thrive in such conditions are usually small, humidity-loving species that prefer indirect light. They also tend to be slow-growing, which is crucial for maintaining balance within the limited space of the terrarium. Let’s explore the best options and why they’re so well-suited.
1. Nerve Plant (Fittonia)
Known for its striking veined leaves, the Nerve Plant comes in a variety of colors, including pink, red, and white. It’s compact, thrives in high humidity, and loves indirect light, making it a perfect match for closed terrariums.
Pro Tip:
If your Nerve Plant starts to look droopy, it’s a sign that it needs a little more moisture. This is one of the easiest plants to care for in a sealed environment.
2. Baby’s Tears (Soleirolia soleirolii)
With its tiny, delicate leaves that form a lush carpet, Baby’s Tears adds an enchanting touch to any terrarium. It’s a ground-covering plant that thrives in the high humidity of closed environments.
