Another from my archive of plants I've never been able to correctly identify.There seem to be lots that look like it and I can't tell the difference...IIRC the flowers are about one and a half inches across. ( photo / image / picture from Kiasmum's Garden ) Cayuga Morning wondered if they're tansy or marigolds but I have tansy and the flowers are much more compact and tightly wrapped.
These come in yellow just like yours, I just haven't uploaded a photo of mine yet and the leaves on the yellow are a little different on the pink colored ones. check ou..... Argyranthemum frutescens (Marguerite Daisy, Cobbitty Daisy)
Thank you for the suggestions.I've looked at both in my RHS A-Z Encycloaedia of Garden Plants and I'm even more confused now but I think they look more like the Anthemis tinctoria,so until I find out otherwise this is what I'll call them in my Lightroom catalogue.
