Perth Groundsel

I am a weed.

This lovely looking yellow flower has been the subject of considerable debate amongst weeders in Jirdarup– is it a weed? Is it a native plant?

The jury is in. Senecio condyles, commonly known as Perth Groundsel, used to be considered a native that colonised disturbed areas, but it is now considered a weed.

This 2017 paper by Greg Keighery Status of Senecio condylus (Asteraceae) in Western Australia has a good description on how it differs from other Senecio.

The purple pigmentation on the outer floral bracts which is characteristic have been circled in one of these photos.
