African feather grass
|Botanical Name||Pennisetum macrourum|
DescriptionGrass forming large clumps with rhizomes (underground stems). Seed head stalks 2 m or more tall. Similar plant to pampas but with a slender and smaller seed head.
Where is it found?Pastures, roadsides, wasteland and urban areas. Likes damp situations such as swamps and along the borders of streams, but can tolerate drought and establish on dry shady banks; prefers light sandy soil. In the Bay of Plenty Region most sites of African feather are found around the Rotorua Lakes.
Why is it a problem?Forms dense clumps that exclude other vegetation.
How does it spread?New colonies will arise from moved or broken rhizomes. Barbed bristles on seed husk assist dispersal by wind and in animal hair.
How do I get rid of it?
Unpalatable to stock.
