Hicaquillo: A Rare Puerto Rican Plant That’s More Mystery Than Garden Material

If you’ve stumbled across the name hicaquillo while researching native Puerto Rican plants, you’ve discovered one of the island’s most elusive botanical mysteries. This fascinating plant, scientifically known as Dendropemon sintenisii, has a story that’s equal parts intriguing and sobering for anyone interested in Caribbean native flora.

What Exactly Is Hicaquillo?

Hicaquillo is a perennial shrub that’s native exclusively to Puerto Rico. Like many plants in the Dendropemon genus, it’s what botanists call a parasitic plant—meaning it depends on other plants (host trees) for its survival. Think of it as nature’s version of a houseguest that never leaves, except in this case, both parties have evolved together over thousands of years.

This multi-stemmed woody plant typically grows to less than 13-16 feet in height, with several stems arising from or near the ground. You might also see it listed under its scientific synonym, Phthirusa sintenisii, in older botanical references.

Where Does Hicaquillo Call Home?

Hicaquillo is found only in Puerto Rico, making it what we call an endemic species. This means it evolved specifically on this island and exists nowhere else in the world naturally.

The Reality Check: Why You Can’t (And Shouldn’t Try to) Grow Hicaquillo

Here’s where we need to have an honest conversation. There are several compelling reasons why hicaquillo isn’t destined for your garden:

  • It’s possibly extinct: Hicaquillo has a Global Conservation Status of SH, which means Possibly Extirpated. In plain English, scientists haven’t seen this plant in the wild for quite some time, though there’s still hope someone might rediscover it.
  • It’s parasitic: Even if you could find seeds or cuttings, hicaquillo requires specific host trees to survive. You can’t just plant it in a pot or garden bed.
  • Extremely limited information: We simply don’t know enough about its specific growing requirements, host preferences, or cultivation needs.

What This Means for Native Plant Enthusiasts

If you’re passionate about supporting Puerto Rican native plants, hicaquillo serves as a powerful reminder of why conservation efforts matter. Rather than trying to grow this particular species, consider these alternatives:

  • Support botanical research and conservation efforts in Puerto Rico
  • Choose other native Puerto Rican plants that are more readily available and better understood
  • Learn about and protect the habitats where rare species like hicaquillo might still exist

The Bigger Picture

While hicaquillo might not be the plant for your garden, its story highlights the incredible diversity and fragility of Caribbean island ecosystems. Every endemic species represents millions of years of evolution and adaptation to very specific conditions.

The fact that we know so little about hicaquillo—from its wildlife benefits to its exact growing conditions—underscores how much we still have to learn about our native flora. It’s a humbling reminder that some plants are best appreciated through conservation efforts rather than cultivation attempts.

What You Can Do Instead

If hicaquillo’s story has sparked your interest in Puerto Rican native plants, focus your gardening efforts on species that are:

  • Well-documented and understood
  • Available through reputable native plant sources
  • Not listed as rare or potentially extinct
  • Suitable for home cultivation

Remember, every native plant we successfully grow in our gardens is a small victory for biodiversity and ecosystem health. While hicaquillo might remain a botanical mystery for now, there are plenty of other Puerto Rican natives waiting to thrive in the right garden setting.
