Good morning everyone. I submit these photos of a Asteracea flourished in Menton (France) in a Mediterranean garden at the end of September. I know that Ateraceae are difficult to identify, but I hope someone recognizes it! Many thanks in advance for your help

I thought it might've been Buphthalmum salicifolium but the petal ends don't look quite right,
cheers

I think it is one of the Heterotheca which are invasive plants from America.

Many thanks to you all! A local  gardener assured me that it is a Heterotheca villosa (Pursh) Shinners (Chrysopsis villosa (Pursh) Nutt. ex DC.). I saw that there are as many as 14 varieties of this species which occupies a very large area, from Canada to Texas! It would be interesting, if it really is a  Heterotheca villosa now as I'm sure it is, to have the possibility to identify the variety ....
