This has appeared for the last couple of years: any ideas what it might be?
Looks like a form of Centaurea/Knapweed.
Thanks for your advice. Centaurea looks the most likely candidate, except for the leaves... when the weather improves I will take a better picture.
It might be a Thalictrum
I also think it's a Thalictrum. How tall is it and do the plants grow more or less singly or are they somewhat mat-forming?
Looks like my Thalictrum aquilegifolium. Has yours got leaves that look like the ones on an aquilegia plant? Hence the name!
Got it: thanks so much. Yes, it's a thalictrum aquilegifolium, which is probably why I kept expecting it to turn into an aquilegia. This is a brilliant forum: we should get together and make a virtual garden!
Glad I could help smallswan. I agree this is brilliant. I love the way everyone helps everyone else. We all learn stuff over the years, but we still need to ask advice with new plants or problems. I just wish I could meet some of these interesting people!
Maybe when we go to flower shows we should wear a badge with our forum name on it, then we could identify each other!
My eyesight is gerring worse. Should have known this, I spent half the afternoon pulling out unwanted seedlings of it.
