Nicaraguan Fountaingrass: A Lesser-Known Ornamental Grass
If you’ve stumbled across the name Nicaraguan fountaingrass (Pennisetum complanatum) in your gardening research, you’ve discovered one of the more elusive members of the fountain grass family. This perennial grass species has found its way into Hawaii’s landscape, though it remains relatively uncommon and understudied compared to its more famous cousins.
What Is Nicaraguan Fountaingrass?
Nicaraguan fountaingrass is a perennial grass that belongs to the diverse Pennisetum genus, known for producing some of our most beloved ornamental grasses. Like other grasses in this family, it’s classified as a graminoid – a fancy term for grass and grass-like plants that includes true grasses, sedges, and rushes.
Despite its common name suggesting Central American origins, this species has established itself in Hawaii, where it reproduces naturally without human intervention and persists in the wild.
Where You’ll Find It
Currently, Nicaraguan fountaingrass is documented as growing in Hawaii, where it has naturalized after being introduced. Its presence in other locations remains unclear, making it something of a botanical mystery.
The Garden Dilemma: To Plant or Not to Plant?
Here’s where things get tricky for gardeners. Nicaraguan fountaingrass sits in that gray area of non-native plants that aren’t officially classified as invasive or problematic, but also aren’t well-documented for their garden performance or ecological impact.
If you’re considering this grass for your landscape, keep in mind:
- Limited availability – you’re unlikely to find it at your local nursery
- Unknown growing requirements and garden performance
- Lack of documented benefits for pollinators and wildlife
- Potential for unpredictable behavior in different climates
Better Alternatives for Your Garden
Instead of hunting down this elusive grass, consider these well-established and beneficial alternatives:
- Native bunch grasses specific to your region
- Purple fountain grass (Pennisetum setaceum) for dramatic texture
- Little bluestem (Schizachyrium scoparium) for wildlife value
- Buffalo grass (Bouteloua dactyloides) for drought tolerance
The Bottom Line
While Nicaraguan fountaingrass isn’t necessarily a bad plant, it’s not necessarily a great garden choice either. The lack of available information about its growing requirements, ecological benefits, and long-term garden performance makes it a risky investment for most gardeners.
Your garden space is precious, and there are so many well-documented, beautiful, and ecologically beneficial grasses to choose from. Why not go with a sure thing that will provide reliable beauty and support local wildlife? Your garden – and the birds and butterflies that visit it – will thank you for choosing plants with proven track records.
If you’re dead set on trying something unusual, consider reaching out to local botanical gardens or native plant societies. They might have insights into this mysterious grass or suggest equally interesting alternatives that are better suited to your specific growing conditions.
