Check sunny slopes for Chilean needle grass

Region: All NZ, except West Coast of the South Island

Chilean needle grass will become evident in pastures during November and December as its distinctive purple-coloured spikelets, with their developing long-awned needle-sharp seeds, emerge from elongating flower stems. Details of this invasive grass can be found here on AgPest. This grass is most likely to be found in pastures on north/west-facing drought-prone slopes.  If you suspect that you have it, please contact your local council biosecurity people for identification and management advice.
