Hi again !!
Thanks ever so much for the very helpful replies. I've followed up the suggestions and now think it's almost certainly Centaurea dealbata 'Steenbergii'. There's even an entry on the GW plant database !!
I've found the plant to be very well behaved unlike certain other cornflowers which spread everywhere!! This year it is less "leggy" than in previous years and despite the regular rain of recent weeks it has not flopped !!!
I have a few more plants to identify but as they have not flowered yet I cannot take proper photos.
Thanks again and happy gardening
