A new weed invasion in Gahnia Grove
In the Arena, at the top where it was previously mown kikuyu.
Giant Swan plant

Apparently there's another species of Swan plant, with ovoid fruit/follicles. This new invasion could be either, at this stage, but is probably Gomphocarpus physocarpus, the species commonly observed in the neighbourhood.
We will probably never know for sure, as I don't intend to become responsible for monitoring its seed spread here by allowing it to grow to fruiting stage.
