As photo attached Weed identification help please north Brisbane.
It's spreading and out competing buffalo grass. The weed can get up to a meter tall seems to have shallow roots and creeps to some extent. Have some growing near a plumbago and when full grown has a similar appearance but obviously not that. Where it's growing near buffalo Yates weed and feed didn't touch it although other weeds turned black.
It starts of low and creeps/spreads quick but once it gets a hold starts to increase in height.
Thanks for any info
