some yellow leafed shrubs burn a bit in full hot sun but it's deciduous so you'll get another set next year
could be, the seed pods look good. A photo of the leaves/whole plant would show for sure.
agree re the spiraea,
disagree re the laurel, flowers are wrong, it's Viburnum tinus.
I think the last rather sick looking yellow one is another weigela
then Viburnum tinus
and maybe another escallonia
the first is a Mahonia, you can prune some of the older stems right to the ground if it gets a bit lanky
2nd an escallonia
Interesting, both those two plants stink. But not for long
Impatient drivers who think everyone else is in the wrong
it' hard to see the leaves on the OP but they don't look like the much divided leaves of Anthemis tinctoria to me. It's still Anthemis tinctoria, whatever cultivar name it's given
GD, I think you said it was in an open garden. Can you ask the garden's owner?
Have to admit not started my research programme yet
