Austrostipa scabra: Australia’s Rough Spear Grass for Your Garden
Meet Austrostipa scabra, commonly known as Rough Spear Grass or Scrub Spear Grass – a distinctive Australian native that’s been quietly winning over gardeners who appreciate its rugged charm and low-maintenance personality. This isn’t your typical lawn grass, but rather a character-filled ornamental that brings texture and movement to landscapes.





What Makes This Grass Special?
Rough Spear Grass lives up to its name with its distinctive rough-textured leaves that feel somewhat sandpapery to the touch. But don’t let that fool you into thinking it’s harsh-looking – this perennial tussock grass has an elegant, fountain-like form that creates beautiful movement in the garden. When it flowers, it produces delicate, feathery seed heads that dance in the breeze and catch the light beautifully.
Where Does It Come From?
This grass is a true blue Australian native, naturally occurring across southeastern Australia including New South Wales, Victoria, South Australia, and Tasmania. You’ll find it growing wild in woodlands, grasslands, and scrublands, where it has adapted to a variety of conditions over thousands of years.
Garden Appeal and Design Role
Rough Spear Grass typically grows 1-3 feet tall and wide, forming neat clumps that work beautifully as:
- Accent plants in native or naturalistic gardens
- Erosion control on slopes
- Textural contrast in mixed plantings
- Low-water feature plants in drought-tolerant landscapes
Its moderate growth rate means it won’t take over your garden, but it will establish a strong presence once settled in.
Growing Conditions
This is where Rough Spear Grass really shines – it’s remarkably adaptable and low-maintenance:
- Sunlight: Full sun to partial shade
- Soil: Well-draining soils, tolerates poor soils
- Water: Drought tolerant once established, minimal watering needed
- Climate: Best suited to USDA zones 8-10
Planting and Care Tips
Getting started with Rough Spear Grass is straightforward:
- Grow from seed sown in spring or fall
- Plant in well-draining soil – it doesn’t like wet feet
- Water regularly during establishment, then reduce significantly
- Trim back old growth annually to maintain appearance
- Very little fertilizer needed – it prefers lean conditions
Wildlife and Ecosystem Benefits
While Rough Spear Grass is wind-pollinated and doesn’t attract pollinators directly, it provides valuable habitat for small wildlife and insects. The seed heads offer food for birds, and the tussock form creates shelter for small creatures.
Should You Grow It?
If you live in Australia, absolutely consider this native beauty for low-maintenance, water-wise gardening. For gardeners in other regions, while this grass isn’t invasive, you might want to explore native grasses in your area first – every region has its own spectacular native grasses that will be even better adapted to local conditions and support local ecosystems.
Rough Spear Grass is perfect for gardeners who love the look of ornamental grasses but want something that won’t demand constant attention. It’s drought-tolerant, deer-resistant, and brings a distinctly Australian character to any landscape lucky enough to host it.
