Long-style feather grass is a tufted grass with prominent feathery seed heads. It is not eaten by livestock and can take over pastures.
Long-style feather grass has been frequently cultivated as an ornamental grass in Australia, and is often a weed of footpaths and vacant land. It is unpalatable to stock and able to increase in infested pastures.
Long-style feather grass is a densely tufted rhizomatous perennial grass growing to 90 centimetres high. It is distinguished by dense, cylindrical seed heads up to 12 centimetres long and 2 centimetres wide, surrounded at their bases with light green or white bristles up to 7 centimetres long. It has dense branching roots up to 60 cm deep.
This plant was previously named Pennisetum villosum.
Long-style feather grass can grow in arid and semi-arid climates if there is enough water available. It is often found along waterways and disturbed sites such as roadsides. It is scattered across many parts of NSW.
Long-style feather grass is native to northern Africa and the Arabian Peninsula.
