Caroline Ground Orchid: A Rare Pacific Gem for Specialized Gardens
Meet the Caroline ground orchid (Spathoglottis carolinensis), a fascinating native orchid that calls the tropical Pacific islands home. If you’re dreaming of adding an exotic touch to your garden, this lesser-known beauty might catch your eye – though it comes with some unique challenges that make it quite different from your typical garden center finds.


What Makes This Orchid Special?
The Caroline ground orchid is a perennial terrestrial orchid, which means it grows in soil rather than perching on trees like many of its tropical cousins. As a forb, it’s an herbaceous plant without woody stems, sending up its growth from underground structures each growing season. In Palau, locals know it as liselabeab, highlighting its cultural significance in Pacific island communities.
Where Does It Call Home?
This orchid is native to the Pacific Basin (excluding Hawaii) and naturally occurs in Guam and Palau. It’s perfectly adapted to the tropical island conditions of these regions, which gives us clues about what it might need in cultivation.
Should You Grow Caroline Ground Orchid?
Here’s where things get interesting – and a bit challenging. While this native orchid sounds appealing, there’s limited information available about its specific growing requirements, availability, and garden performance. This rarity in cultivation information suggests a few important considerations:
- It may be difficult to source from reputable nurseries
- Growing requirements are not well-documented for home gardeners
- Success rates in cultivation outside its native range are unknown
- It may require very specific tropical conditions that are hard to replicate
Growing Conditions and Care
Based on its native habitat in tropical Pacific islands, the Caroline ground orchid would likely prefer:
- Warm, humid conditions year-round
- Well-draining but moisture-retentive soil
- Filtered light or partial shade
- Protection from strong winds
- Consistent temperatures without dramatic fluctuations
However, specific soil pH preferences, fertilizer needs, and detailed care instructions remain unclear due to limited cultivation research.
The Bottom Line
While the Caroline ground orchid represents an intriguing piece of Pacific island flora, its limited availability and lack of established growing guidelines make it a challenging choice for most gardeners. If you’re in a tropical climate similar to Guam or Palau and can source this orchid responsibly, it could be a unique addition to a specialized native plant collection.
For most gardeners interested in ground orchids, consider exploring more readily available terrestrial orchids that are better suited to cultivation, such as hardy native orchids appropriate for your specific region. Your local native plant society can help guide you toward orchid species that are both available and suitable for your climate and gardening experience level.
A Word About Conservation
Given the limited range and specialized habitat of the Caroline ground orchid, it’s especially important to source any plants through reputable, conservation-minded suppliers who can verify the plants weren’t collected from wild populations. Supporting responsible cultivation helps protect these unique Pacific island treasures for future generations to appreciate.
