When I was a child (in south west Scotland, but I don't think the location is relevant) I used to see some smallish ground plants which I used to call sunflowers. They were definitely NOT sunflowers - I used to call them that because the heads only opened when the sun was on them.
They were a little like daisies, with mainly white petals, with coloured tips, but the heads were bigger than daisies.
Does this ring any bells with anyone? I'd love to have some in my garden.
I've tried a google search but not got anywhere - but all I could think of to search for was "daisies" which only returned the predictable results.
To think that London, or anywhere else for that matter, does not belong to any one demographic
