I must thank you for your help. I do have Aubretia in the garden, but this Campanula portenschlagiana is proving a rampant pest. My mistake on I.D. as it has grown everywhere,
I have a problem with Digitalis, as they too grow in the most obscure places and have to be weeded out, each spring. In the old vegetable garden as the pH is acid, wild Lupins are a major pest.
Thanks once again, for your most kind help.
Regards from across the Atlantic.
Neil.
p.s. Loads of weeding to do!
One of my Calla lilies.
