Vetivergrass: The Aromatic Non-Native Grass Worth Considering
If you’re looking for a grass that’s both practical and pleasantly fragrant, vetivergrass (Vetiveria) might catch your attention. This perennial grass has been quietly making its way across parts of the southern United States, establishing itself as more than just another ornamental option.
What Exactly Is Vetivergrass?
Vetivergrass is a non-native perennial grass that originally hails from Asia, particularly India. Don’t let its humble grass appearance fool you – this plant packs some interesting qualities that have made it useful to humans for centuries. It’s a clumping grass that grows in dense tufts, and here’s the kicker: its roots are incredibly aromatic, producing a distinctive earthy, woody scent that’s prized in perfumery and aromatherapy.
Where You’ll Find It Growing
Currently, vetivergrass has established itself in Louisiana, Texas, Palau, and Puerto Rico. It’s considered an introduced species that reproduces on its own in these areas, meaning it’s found its comfort zone in warmer climates.
The Garden Appeal
So why might you want this grass in your landscape? Vetivergrass brings several practical benefits to the table:
- Excellent for erosion control on slopes and hillsides
- Drought tolerant once established
- Forms attractive clumps that add texture to the landscape
- The fragrant roots can be harvested for natural aromatherapy uses
- Low maintenance once it gets going
Growing Conditions and Care
Vetivergrass is surprisingly easygoing when it comes to growing conditions. It thrives in full sun and prefers well-draining soil, though it can tolerate a range of soil types once established. This grass is generally suited for USDA hardiness zones 8-11, making it ideal for southern gardeners.
For planting, you’ll typically work with divisions or transplants rather than seeds. Space them adequately to allow for their clumping growth habit – they can reach several feet in both height and spread when mature.
Care and Maintenance
Once established, vetivergrass is refreshingly low-maintenance. Water regularly during the first growing season to help it establish, then reduce watering as it becomes drought tolerant. You can cut it back in late winter or early spring before new growth begins.
A Word of Caution and Alternatives
While vetivergrass isn’t currently listed as invasive in most areas, it’s always worth considering native alternatives that provide similar benefits while supporting local ecosystems. Some excellent native grass options to consider include:
- Big bluestem (Andropogon gerardii) for tall grass prairie effects
- Little bluestem (Schizachyrium scoparium) for smaller spaces
- Gulf muhly (Muhlenbergia capillaris) for ornamental appeal
The Bottom Line
Vetivergrass can be a useful addition to southern landscapes, particularly if you’re dealing with erosion issues or want a low-maintenance grass with unique aromatic properties. However, always check local regulations and consider native alternatives that might provide similar benefits while supporting local wildlife. If you do choose to plant vetivergrass, enjoy its practical benefits and that distinctive fragrance – just remember to be a responsible gardener and monitor its spread in your landscape.
