While most of us are used to seeing exotic orchids in pots, their unique growth habits and specific needs actually make them perfect for creative displays. If you really want to see these beauties thrive, a terrarium is a fantastic option that highlights their unique beauty in a way a standard windowsill just can’t.
Why a Terrarium is the Perfect Orchid Home
Because of their enclosed design, terrariums create a little microclimate that orchids absolutely love. Generally speaking, these plants crave a bright, warm location with plenty of humidity. A glass-walled terrarium checks all those boxes perfectly. Plus, those transparent walls don’t just let in the light your orchids need—they also give you a front-row seat to enjoy those stunning, exotic blooms from every angle.
The Best Orchid Varieties for Your Terrarium
If you’re setting up a warm, humid terrarium, you’ll want to look for “warm-house” orchids. These tropical varieties naturally prefer temperatures that stay at or above 68°F (20°C).
Some of the best orchid species for terrarium life include:
- The classic Phalaenopsis (Moth Orchid)
- The striking Vanda orchid
- Dendrobium (often called Cane Orchids)
- Oncidium (Dancing Lady Orchids)
- Epidendrum, which hails from the lush South American rainforests.
Unique Exotic Finds for Your Terrarium
If you want to move beyond the classics and add some real “wow” factor to your glass garden, there are some truly extraordinary species to consider. Keep an eye out for:
- Cirrhopetalum bicolor
- Doritaenopsis
- The wonderfully fragrant Aerangis.
Orchids for Small Terrariums
Orchids usually need a bit of elbow room for their roots and flowers to really show off. But don’t worry—if you’re working with a compact terrarium or one that’s already crowded with other plant friends, you don’t have to miss out on the orchid action.
Simply reach for some miniature orchid varieties like these:
- Amesiella minor
- Aerangis biloba
- Barbosella cucullata
- Ionopsis utricularioides
A Special Ground-Dweller: The Jewel Orchid
If you’re looking to fill in the “floor” of your terrarium, Macodes sanderiana is a total showstopper. Known as a Jewel Orchid, this is a terrestrial species, meaning it grows in the soil. Since it stays grounded, it won’t compete for space with your epiphytic (air-growing) orchids mounted higher up.
Choosing the Right Substrate
When you’re setting up your orchid terrarium, the foundation is key. You want a base that helps manage moisture without letting things get swampy. A layer of expanded clay pebbles (LECA) is an excellent choice because it helps maintain that humidity orchids crave while providing great drainage.
