Correctly Identifying Serrated Tussock
Too often, native grasses such as native or silver tussock (Poa labillardieri) are killed by landholders who mistake them for serrated tussock (Nassella trichotoma).
A new identification brochure being developed by the VSTWP (Victorian Serrated Tussock Working Party) will ensure this doesn’t happen anymore.
The identification brochure due to be released next month will contain information on how to identify serrated tussock as well as other Nassella species and similar looking native grasses.
With more than 40 photos along with descriptions, land managers of serrated tussock will be sure to get the identification right.

Now is the easiest time of the year to identify serrated tussock as it is in flower. From a distance, mature serrated tussock plants will have a purple-maroon tinge – which is the 100,000 seeds mature plants are capable of supporting.
On a closer look the branched flower head of serrated tussock is significantly different to any other Nassella species or native grass species.
The most common form of identification when serrated tussock is not in flower is the ‘roll test’. Serrated tussock leaves will roll smoothly between the thumb and forefinger like a needle. Most native species such as Poa labillardieri will have flat edges so won’t roll as smoothly.
