Windmill grass can be either annual or short term perennial and forms a rounded tussock usually less than 50 cm tall. The stems are smooth with two to three nodes towards the base which may form roots at the nodes. The roots at the nodes enable the plant to spread across the soil surface. The leaves are flat, without hairs and are rough to the touch. They are up to 14 cm long and two to five centimetres wide. Flowerheads have six to nine spikes all spreading out from a common point forming an umbrella shape.

Tolerance High heat tolerance
High drought tolerance
Low frost tolerance
Soil Windmill grass grows on clay soils in drier areas of the states, but favours red or black earths. It is a primary coloniser of bare soil areas and will rapidly occupy denuded areas.

Seed should be sown into a weed free seed bed in early spring. It is preferable to lightly scratch or scarify the soil to create niches for the seed to lodge in. The seed should not be sown deep, but would be best broadcast over the surface then incorporated into the top 5mm of the surface by dragging over a set of harrows or similar equipment.

Sowing rate Sow seed at a rate of 1 - 2 kg per hectare for revegetation
Uses Revegetation and land rehabilitation
