I bought 6 of these last year to fill in gaps. This year they have come up everywhere & I’m hoping they’ll do likewise next year. Easy to get rid of if there are too many. I had to re log in to get the photo up, with password etc.

Doronicum caucasicum 'Little Leo' was my thought.

Santivalia ?

i think Santivalia a better match. Doronicum is a spring flowerer and the flower's are 'looser'

Oh sorry, it should be Sanvitalia lol that's what you get for rushing :D

Thank you all. I have made a note of Sanvitalia. That name does ring a bell from last year. They are bright little things & so easy.

Melampodium ("Butter Daisy") ?

Just looked up your id, but I think that Sanvitalia procumbens is the correct one. Ty for your input, it made me look up both of them.
