Nutrush: A Rare Pacific Sedge Worth Knowing About
If you’re a collector of unusual native plants or have connections to Pacific island ecosystems, you might have stumbled across nutrush (Scleria levis). This perennial sedge is one of those plants that flies under the radar – and for good reason. It’s not exactly what you’d call a garden center staple!
What is Nutrush?
Nutrush is a grass-like perennial that belongs to the sedge family (Cyperaceae). Like other sedges, it has that distinctive triangular stem that sets it apart from true grasses. You might also see it listed under its botanical synonym, Scleria laevis, in some older references.
This plant is part of a larger group of sedges known for their often inconspicuous flowers and their ability to thrive in various moisture conditions – though specific details about nutrush’s preferences remain somewhat mysterious in horticultural circles.
Where Does Nutrush Call Home?
Here’s where things get interesting (and limiting): nutrush is native to the Pacific Basin, specifically found in Guam and Palau. This incredibly restricted natural range means most of us will never encounter this plant in the wild, and it’s certainly not adapted to temperate North American growing conditions.
Should You Try Growing Nutrush?
Let’s be honest – unless you’re living in or very near the Pacific islands where this sedge naturally occurs, nutrush probably isn’t the plant for you. Here’s why:
- Extremely limited availability – you’re unlikely to find it at any nursery
- Adapted to very specific Pacific island conditions
- No established cultivation guidelines for other climates
- Unknown hardiness zones for temperate regions
Better Alternatives for Most Gardeners
If you’re drawn to the idea of native sedges in your landscape, consider looking for species that are actually native to your region instead. North American gardeners have wonderful options like:
- Pennsylvania sedge (Carex pensylvanica) for woodland gardens
- Fox sedge (Carex vulpinoidea) for wet areas
- Prairie sedge (Carex prairea) for prairie-style plantings
These alternatives will be much easier to find, grow, and maintain while still providing the grass-like texture and ecological benefits that make sedges so valuable in native plant gardens.
The Takeaway
Nutrush represents one of those fascinating plant species that reminds us how diverse and specialized our world’s flora can be. While it’s not practical for most of our gardens, it plays an important role in its Pacific island ecosystems. Sometimes the best way to appreciate a plant is simply knowing it exists and supporting conservation efforts in its native habitat.
If you’re passionate about Pacific island plants and happen to live in a suitable climate, connecting with botanical gardens or conservation organizations in that region might be your best bet for learning more about this elusive sedge.
