Anyone identify these plants?

We don't get them [hummingbird h.moth] up here where I am in the west, although I think the east side gets a few pockets.
I grow the red centranthus- from seed I collected along a small verge. I'd like the white one too but I'd need to buy seed as we don't see it round here.

 

It grows all over my area as a pavement weed and I've been waiting for it to arrive in my garden - no luck, even though I've seen it in next door's gravel. So this year I've bought some seed. I thought if anything can survive on my steep, stony slope, that will.

Same issue with Fox and Cubs, house a few doors down has a front garden smothered in it, but I've had to buy seed.

 

It grows all over the Isle of Man too.

 

We have all 3 colours in our garden.
It comes back in the same places every year bigger than ever, and constantly appears in new places.
It’s on the grass verges up and down the road, and some gardens on the road are completely covered in it.
I like it, but like to keep it under control to a certain point, the people on the street who seem less keen on gardening just seem to have let it run riot in their gardens.
