I think you're right with 2 Hostafan. It's had a pudding basin haircut instead of a prune.
Field scabious have arrived thank you Fishy
also the asters that get mildew but I love all the others.
Sorry about the spiorrhoeas Hostafan.
spireas (any), garish, tender annuals/perennials
Wait for a second opinion kirst but that's what it looks like to me.
A suitable reward for nicking someone else's plant I think
I think that's Potentilla anserina, silverweed. The manner of growth you describe sounds right as well.
Also think it may have been renamed and now called Anserina something, maybe argentina
They're all right in their place pansyface but their place isn't my shed. Or my roof space, they're too noisy.
