Commented in the 'natives' forum just now. Looking again, yes, those do indeed appear to be flowering stalks. Image is quite small. Is there any chance you can provide some additional pics, showing details and closeups of the flower, etc?

Looks like senecio aurea (golden ragweed), if the blooms are yellow.

I am going to make a guess "pennywort". The pic doesn't quite show the plants texture of the leaves on top, if the leaves are smooth on top or hairy etc. My guess is likely wrong, but, it could be a form of "pennywort", without smooth and dark green leaves, but, medium green and slightly hairy leaves.

Poaky - this post is 18 months old so I doubt the OP is watching. 'Pennywort' is a common name given to several different plant species but none of them produce flower spikes with purple buds.

Okay Floral, 18 months isn't that long, but they likely tried the name that plant forum.

violets - not sure what species

Oh no, not Violets, Camp. Click on the image and you'll get an enlargement. It shows tallish flowering stems with clusters of what look like Asteraceae flower buds at the top. The OP is long gone. They posted in both Name That Plant and Native Plants too and accepted Packera aurea as the id.
