Tall but unsure what is what

in Plants
here are two tall plants growing in my tubs.... one I posted a couple of weeks ago seemed to be cosmos...but is now definitely looking like that is wrong. The others I know I planted some biannuals last year but tags have gone awry... I was thinking possibly larkspur, delphiniums or hollyhocks but I’m really not sure as leaves shown on internet pickiest seem to concentrate on the flowers so no clear leaf shapes! Any ideas?


Marne la vallée, basically just outside Paris 🇫🇷, but definitely Scottish at heart.
