Austrostipa Pubescens is a Spear Grass that grows in Heathland.
Overview of Austrostipa Pubescens
• They grow in sandy areas in eastern Australia.
• It grows in the form of a tufted bunchgrass.
• It can grow up to a height of 1.5 metres.
• The specific epithet pubescens translates to “softly hairy”.
• It first came in scientific literature in 1810.
• This was authored by Robert Brown who was a prolific Scottish botanist.
• It is a Caespitose perennial.
• It can grow to 1.5 m high.
• It has conspicuously extravaginal shoots from a short rhizome.
• The leaves are ligule leathery and truncate.
• It is occasionally slightly obtuse.

• Stipa species and cultivars are all easily grown in any moderately fertile, well-drained soil in full sun.
• Most are hardy to at least -15°C.
• Though many will not survive the winter conditions where the soil is waterlogged.
• Plants should establish quickly.
• Once growing well they need little attention apart from cutting back of the foliage during the winter.
• This is to clean up prior to the new flush of growth that appears in the spring.
• It is not troubled by pests or diseases.
• Spear grasses grow on a wide range of soil types.
• These species grow well on poor soils.
• They also prefer soils that have high acidity.
• Tall Spear grass grows well in loam soils which have moderate to low pH.
• These species are high drought resistance.
Other tolerances of these species are:
– Low fertility tolerant
– Acid soil tolerant
– Frost tolerant
• The seeds should be sown below 5-10 mm of the soil surface when there is availability of moisture.
• Spear grass grows well when sown during autumn or winter.
• In the cooler months, germination can take from 6–8 weeks.
• In the warmer months, it may be 7–10 days.
• Keep the soil moist.
• Do not water log the soil for three weeks after sowing.
• Sowing of seeds can be done with or without awns.
• Sow the seeds with awn so that they are able to move during watering.
• This will help the awn to find a space for its burial.
• It is more difficult to sow this way.
• It generally requires hand sowing.
• Sowing the seeds without awns is easier.
• It requires sowing into a groove or shallow trench.
