Impact

Long-style feather grass (also known as feathertop grass and white foxtail 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 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.
