Purple pigeon grass is a perennial summer-growing tussock grass.Purple pigeon grass (Setaria incrassata cv. Inverell) is a perennial summer-growing tussock grass for areas with an annual rainfall of more than 500 mm. It is tolerant of drought and cool conditions, but is sensitive to frost.A valuable characteristic is its ability to germinate and establish more reliably than most other tropical grasses on medium- and heavy-cracking clay soils of the Darling Downs, the brigalow lands, and the Maranoa, where establishment of other tropical grasses has been poor.Purple pigeon grass is suitable for permanent or ley pastures in a crop-pasture rotation. It will seed throughout the growing season, and can establish freely from fallen seed.
