Mock Bluestem: A Rare Puerto Rican Native Grass Worth Knowing About

If you’re passionate about native plants and happen to garden in Puerto Rico, you might want to learn about mock bluestem (Euclasta condylotricha). This perennial grass is one of those quiet natives that doesn’t get much attention in gardening circles, but that doesn’t mean it isn’t worth considering for the right situation.

What Is Mock Bluestem?

Mock bluestem is a perennial grass that belongs to the large and diverse grass family (Poaceae). You might also see it listed under its scientific synonym, Andropogon condylotrichus, in older botanical references. As its common name suggests, it resembles the more widely known bluestem grasses, though it’s in its own unique genus.

Where Does Mock Bluestem Grow?

This grass is native exclusively to Puerto Rico, making it a true island endemic. If you’re gardening anywhere else, this particular species won’t be an option for you, but understanding these unique natives helps us appreciate the incredible plant diversity of Caribbean ecosystems.

The Challenge of Growing Mock Bluestem

Here’s where things get a bit tricky for gardeners interested in this grass: there’s very little documented information about growing Euclasta condylotricha in cultivation. This isn’t uncommon with lesser-known native species, especially those with limited natural ranges.

What We Do Know

Based on the available information, here’s what we can tell you about mock bluestem:

  • It’s a perennial grass, meaning it comes back year after year
  • As a native Puerto Rican species, it’s adapted to tropical conditions
  • Being a grass, it likely provides some wildlife value, though specific benefits aren’t well documented
  • It would be most appropriate for native plant gardens or naturalistic landscapes in Puerto Rico

Should You Try Growing It?

If you’re gardening in Puerto Rico and passionate about growing native species, mock bluestem could be an interesting addition to a native plant collection. However, you’ll want to proceed thoughtfully:

  • Source plants or seeds only from reputable native plant nurseries
  • Never collect from wild populations
  • Be prepared to experiment with growing conditions, as specific requirements aren’t well established
  • Consider it more of a conservation effort than a typical landscaping choice

Alternative Native Grasses

If mock bluestem proves difficult to source or grow, Puerto Rico has other beautiful native grasses that might be more readily available and better understood in cultivation. Working with local native plant societies or botanical gardens can help you identify suitable alternatives that will provide similar ecological benefits with more established growing guidelines.

The Bigger Picture

Plants like mock bluestem remind us that there’s still so much to learn about our native flora. Even if you never grow this particular grass, knowing it exists helps us appreciate the unique plant communities that make each region special. And who knows? Maybe your interest in lesser-known natives like this one will inspire more research and cultivation efforts in the future.

For Puerto Rican gardeners interested in supporting native biodiversity, every native species we can successfully grow and propagate is a small victory for conservation. Mock bluestem might be challenging to find and grow, but for the right gardener in the right place, it could be a meaningful addition to a native plant collection.
