Bejuco de Agua: A Lesser-Known Puerto Rican Native Climber

If you’re passionate about native plants and happen to be gardening in Puerto Rico, you might be intrigued by a climbing species that goes by the charming name of bejuco de agua (Pinzona coriacea). This perennial climber represents one of those fascinating native plants that often flies under the radar in mainstream gardening circles, yet holds potential value for those seeking to create authentic, locally-adapted landscapes.

What Makes Bejuco de Agua Special?

Bejuco de agua is a twining, climbing plant with stems that can develop woody characteristics over time. As a true Puerto Rican native, this species has evolved alongside the island’s unique ecosystem, making it naturally adapted to local growing conditions. The plant was historically classified under the synonym Doliocarpus calinoides, which you might encounter in older botanical references.

Where You’ll Find It Growing

This climbing native is endemic to Puerto Rico, meaning it naturally occurs nowhere else in the world. This exclusivity makes it particularly special for local gardeners who want to support indigenous biodiversity and create landscapes that reflect the island’s natural heritage.

Should You Plant Bejuco de Agua?

Here’s where things get a bit tricky – and honestly, quite intriguing from a gardening detective standpoint. While we know this plant is a legitimate Puerto Rican native with climbing habits, detailed horticultural information remains surprisingly scarce. This could mean several things:

  • It might be a rare species that deserves conservation attention
  • It could be challenging to cultivate outside its natural habitat
  • It may simply be understudied from a gardening perspective

A Cautious Gardening Approach

Given the limited available information about bejuco de agua’s growing requirements, invasive potential, and garden performance, we’d recommend proceeding thoughtfully if you’re considering adding it to your landscape. Here are some wise steps to take:

  • Contact local botanical gardens or native plant societies in Puerto Rico for guidance
  • Ensure any plant material is sourced responsibly and legally
  • Consider it for naturalistic or restoration-focused landscape projects rather than formal gardens
  • Monitor its growth carefully if you do plant it, noting its behavior and needs

Alternative Native Climbers

If you’re drawn to the idea of native climbing plants for Puerto Rico but want something with more established cultivation information, consider exploring other well-documented native vines. Local extension offices and native plant societies can point you toward climbing natives with proven garden performance.
