Moco de Pavo: A Native Puerto Rican Grass Worth Discovering
If you’re gardening in Puerto Rico or other tropical locations and looking to support native plant communities, you might want to get acquainted with moco de pavo. This perennial grass, scientifically known as Eriochrysis cayennensis, represents one of the lesser-known but authentic native species that call Puerto Rico home.

What Makes Moco de Pavo Special?
Moco de pavo belongs to the grass family (Poaceae), making it a true grass rather than just a grass-like plant. As a perennial, this species returns year after year, potentially providing long-term value in native plant gardens and naturalized landscapes.
What sets this grass apart is its authentic native status in Puerto Rico. In a world where many landscapes are dominated by non-native species, choosing plants like moco de pavo helps maintain the ecological integrity of local plant communities.
Where You’ll Find This Native Grass
Eriochrysis cayennensis is native to Puerto Rico, where it has evolved alongside the island’s unique climate and ecosystem conditions. This grass is specifically adapted to the tropical conditions found in this region.
Is Moco de Pavo Right for Your Garden?
Unfortunately, detailed information about this particular species’ specific growing requirements, appearance, and garden performance is quite limited in readily available sources. This isn’t uncommon for lesser-known native species, especially tropical grasses that haven’t received as much horticultural attention as showier flowering plants.
However, if you’re gardening in Puerto Rico or similar tropical climates, moco de pavo could be worth investigating for several reasons:
- It’s authentically native to the region
- As a perennial, it provides lasting value
- Native grasses often require less maintenance once established
- It supports local ecosystem relationships
Growing Conditions and Care
While specific growing requirements for moco de pavo aren’t well-documented, we can make educated assumptions based on its native habitat. This grass likely thrives in:
- Warm, tropical conditions (probably USDA zones 10-11)
- Areas with adequate moisture and humidity
- Well-draining soils typical of tropical environments
As with most native plants, moco de pavo would probably perform best when grown in conditions that mimic its natural habitat.
A Note for the Curious Gardener
If you’re intrigued by moco de pavo, you might need to do some detective work. Consider reaching out to local botanical gardens, native plant societies, or university extension services in Puerto Rico. These organizations often have knowledge about lesser-known native species and might be able to provide seeds or growing guidance.
The limited available information about this grass highlights an important point: there are many native species that deserve more attention and study. By choosing to grow and learn about plants like moco de pavo, gardeners can contribute to preserving and understanding local botanical heritage.
The Bottom Line
While we’d love to give you detailed growing instructions and glowing descriptions of moco de pavo’s ornamental qualities, sometimes the most honest thing we can do is acknowledge the gaps in our knowledge. What we do know is that this grass represents an authentic piece of Puerto Rico’s native plant community – and that alone makes it worth considering for gardeners committed to supporting local ecosystems.
