While I am at it - can I get help with 2 more identifications.
This one:

And this one:

The first looks like Euphorbia robbiea, aka Mrs Robb's Bonnet (and yes, it's a traveller!!)

The second looks like some sort of mugwort, Artemisia.

And the third it is difficult to determine the scale of.....I might be inclined towards Lysimachia.

The last one looks like a Sedum growing in too much shade.

Nr 2 could be Artemisia ludoviciana, nr 3 is definitely a Sedum,

Thanks so much everyone...

First reminds me of a yellow primrose buttercup.
