If you want to identify a weed from scratch, we suggest you consult the interactive key below.
You can also check our WeedScan page, with links through to our new WeedScan plant identification application (a smartphone app is coming!).
And of course you can share photos to plant identification groups on Facebook (for example, Plant Identification Australia) or iNaturalist, and members of these groups will provide their suggested identifications.
If you still can’t identify your weed, visit our Connect page which provides contact details for your state or territory’s herbarium.
