Not sure why this has been featured. It was one plant in a small number in this area, when I was checking my phone GPS. There are millions of these plants in other areas, so that the grasslands are in fact weedlands. This invasive plant is totally out of control.

I imagine I accidentally bumped the feature button, I could remove it If you would prefer.

Let's leave it as publicity for the ACT Weeds Manual https://sactcg.org.au/wp-content/uploads/2023/10/ACT-Weeds-Manual-23.pdf which shows how volunteers are tackling weed control, including St John's wort.

PS Don't try looking for the ACT Weed Manual because that gets a different result.
