Kangaroo Grass

Themeda triandra

The Story

Plant Bio

Themeda triandra is a densely tufted, erect perennial grass native to Africa, Asia, and Australia, forming clumps of delicate, arching foliage. The narrow linear leaves transition from green or blue-green to distinct pink and orange-brown tones during the warmer months.

This species is distinguished by its large, branching red-brown spikelets that bear prominent, dark awns up to three inches long. It exhibits exceptional drought tolerance once established and adapts readily to nutrient-poor soils.

Uses & Benefits:

Ornamental UsesProvides architectural structure with arching foliage that turns copper-red in autumn, topped by dark-awned seed heads.
Practical UsesRequires zero supplemental fertilizer and minimal irrigation once established in the landscape.
Ecological BenefitsActs as an effective soil binder for erosion control on dry slopes and banks.

Planting

How to Grow

  1. Sow seeds in a well-drained propagation mix, applying light or specialized pre-treatment to overcome the natural twelve-month dormancy.
  2. Transplant young plugs into a full sun to partially shaded position in well-drained soil.
  3. Water moderately during the first active growing season to establish a deep root system.
  4. Cease regular irrigation once established, as the mature grass relies on natural rainfall and tolerates dry conditions.

Pro Tip

Avoid frequent or low mowing, which severely weakens the root system; instead, cut the foliage back hard only once every few years to clear out dead thatch.

Keep It Thriving

Care Guide

Do

  • Grow in well-drained sandy loams or clay soils.
  • Allow the foliage to flush with orange-brown tones in late summer.
  • Provide full sun to maximize spikelet development.

Don't

  • Do not plant in waterlogged or poorly drained sites.
  • Do not apply heavy fertilizers, as the plant thrives in low-nutrient soils.
  • Do not shear the grass annually, which depletes its energy reserves.

Common Questions

Kangaroo Grass questions

What zones can Kangaroo Grass grow in?

Kangaroo Grass is hardy in USDA Zones 8–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

When does Kangaroo Grass bloom?

Kangaroo Grass typically blooms in summer through late summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does Kangaroo Grass need full sun?

Kangaroo Grass does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.

Is Kangaroo Grass drought tolerant?

Yes — once established (usually after the first full season), Kangaroo Grass handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
