Custard Orchid: A Rare Puerto Rican Treasure Worth Protecting

If you’ve stumbled across the name custard orchid in your native plant research, you’ve discovered one of Puerto Rico’s botanical gems. The custard orchid (Eurystyles ananassocomos) is a fascinating native orchid that deserves our attention—not necessarily for our gardens, but for our conservation efforts.

What Makes the Custard Orchid Special?

The custard orchid is a perennial forb, which means it’s an herbaceous plant without significant woody growth above ground. Like other orchids, it’s a monocot that returns year after year, storing energy in underground structures during dormant periods. As a member of the orchid family, it likely produces the intricate, specialized flowers that make orchids so captivating to plant enthusiasts.

Where Does It Call Home?

This special orchid is endemic to Puerto Rico, meaning it naturally occurs nowhere else in the world. Its entire global population exists within the boundaries of this Caribbean island, making it a true botanical treasure of the region.

A Plant in Need of Protection

Here’s where things get serious: the custard orchid has a Global Conservation Status of S3, which translates to Vulnerable. This means the species is at risk due to its rarity and limited distribution. Scientists estimate there are only 21 to 100 known occurrences of this plant, with somewhere between 3,000 and 10,000 individual plants in existence worldwide.

This rarity status puts the custard orchid in a delicate position. While its uniqueness might make it appealing to collectors, its vulnerable status means we need to be incredibly thoughtful about how we interact with this species.

Should You Grow Custard Orchid?

The short answer is: probably not, unless you’re a specialized orchid conservationist. Here’s why:

  • Limited availability: With so few plants in existence, finding legitimate, responsibly-sourced specimens would be extremely difficult
  • Unknown cultivation requirements: There’s very little information available about how to successfully grow this species
  • Conservation priority: These plants are better left in their natural habitat or in the hands of botanical institutions focused on conservation
  • Specialized needs: Like most native orchids, it likely has very specific growing requirements that would be challenging to replicate

What You Can Do Instead

If you’re passionate about supporting Puerto Rican native plants, consider these alternatives:

  • Support organizations working to protect Puerto Rican native plant habitats
  • Choose other Puerto Rican native plants that are more readily available and less vulnerable
  • Learn about and advocate for orchid conservation efforts
  • Visit botanical gardens that may have conservation programs for rare orchids

The Bigger Picture

The custard orchid reminds us that native plant gardening isn’t just about what we can grow in our own spaces—it’s also about protecting and preserving the incredible biodiversity that exists in wild places. Sometimes the best thing we can do for a rare native plant is to ensure it has a safe, protected habitat where it can thrive without human interference.

While you might not be able to add a custard orchid to your garden, you can still celebrate and protect this remarkable species by supporting conservation efforts and choosing other native plants that are more suitable for cultivation. Every native plant we grow helps create a more biodiverse and resilient ecosystem, even if we can’t grow them all.
