Sow thistle. At my place deer eat most of the flower heads off, preventing seed formation

Probably. But can you show us some leaves to confirm?

definitely a weed.. and you better grab that seed before you have dozens more next year ..

for me.. it doesnt really matter what the name is.. its a heavy reseeding weed ... and the seed have wings .. crikey ..

It's nice that I don't have to worry about weeds like that in my own garden.

Thanks everyone!

Here are more photos, if this one and another that I think must be the same:

Quite possibly Erechtites hieraciifolius but regardless a weed that needs to go.

I think I saw one yesterday……

Thanks for the leaf pix. Erechtites.

Looking at other queries on another platform yesterday I saw that those flower- and seed heads would in fact belong to Erechtites instead of Sonchus.
