Spotting

Thanks chesterbperry,
I think you are right with Senecio, I try to sort it out ;-) and yes I have to take more pics, I always realise that when I'm home !

Looks like it could be a species of Senecio, really need to train yourself to take more comprehensive photos, yellow composites are notoriously difficult. ;)

Thanks Karen,

but I doubt because St John's worth has 5 petals and on the picture there
are 6 of them. It's so difficult and I only have one pic.
