What is this flower please?...

One I would very much like to have in my garden too.. sadly I’ve no idea what it’s called!!

It looks like camomile to me

Looks like chamomile to me too.

Any chance you send a better photo of the leaves, Lucky?

I think because some of the flowers have a pinky tinge, it could be a form of Erigeron.

I agree with Greyd, erigeron. They're well worth having! They flower and flower and survive the winter.

I’m certain you’re right GD.
Erigeron karvinskianus

Cut a little off and take to local nursery or garden centre..

A prolific self seeder. It has a big sister that was growing all over the grounds of the apartment complex we were staying at in Cornwall. I admired it. The owner said “plant it at your peril - it’s a real thug!”

I quite like thugs!!

Me too - I sent for some seeds when we came home. Wrong time to sow them though!

I don't know why I can't get such a thug to grow in my garden unless my suspicions are correct and my gardening friend is pulling it out, possibly thinking it is a weed.

As it is such a thug I wonder if my gardener friend thinks it is a weed and has been pulling mine out. It is very pretty so I will have to try again with a packet of seeds this time as that will be much cheaper than buying garden ready plants.

Well, I thought I had lost my post so tried again and doubled my output in a oner!

Yes. It's Erigeron karvinskianus. Self seeds in cracks and crevices, paths, walls, rockeries etc. Lovely plant.

It is Erigeron karvinskianu, self seeds very easily and looks pretty. If you have a friend with some get a small plant and you will then find it popping up between patio slaps, or along steps or a wall.

I need it to cover a big barren space where nothing else seems to grow. If it is a thug, then bring it on!

It likes well drained soil and dry conditions so is not really happy in damp, heavy clay gardens.
