Paspalidium jubiflorum

Distribution

Warrego grass occurs broadly across Australia as a long-lived perennial grass. It is usually found on the heavier soils of higher fertility, especially those that are associated with either permanent water or with occasional flooding. It is frequently found in dense stands following summer inundation through low-lying areas.

Description

It is a long-lived perennial grass with upright growth and is also known to produce short rhizomes to give rise to ?daughter? plants. It will grow to around 1 metre high with quite thick foliage up to around half the plant height. It flowers in mostly in autumn following heavy summer rainfall and seedheads are very narrow with the seeds held tightly against the central spine of the seedhead.

Habitat/Soil

It is associated with heavier soils and is not commonly found on sandy soils. It seems to be able to grow under a wide range of soil pH conditions and is more defined by its close association with heavier soil types subject to inundation or high soil moisture.

Tolerances

  • Moderate frost tolerance
  • Waterlogging tolerance
  • High heat tolerance
  • Will be grazed out if subject to uncontrolled grazing

Sowing

The seed is relatively easily cleaned and can be sown through any small seed box. It flows easily if cleaned down properly. Seed should not be sown any deeper than 5 mm but does require some soil over the top of the seed. Sowing rates ? 3 to 6 kg per hectare for pasture and revegetation.

Uses

A very useful grass for fodder as it provides excellent quality feed highly sought after by stock. Indeed very early commentary on this grass by Turner (1880) is ?pastoralists very justly hold this grass in much esteem, and many consider it is one of the best that grows in the interior?.
