I'm still finding them!

This pink-flowered feathery-leaved plant is causing me some head scratching. I wondered if it is a wild flower, but nothing found in my fairly comprehensive wildflower book.
I hope I'm not being a pest, but there are several more in the pipeline.

The leaves look like Yarrow (Achillea) could be some variety of that.

Yes, it's an Achillea. They come in red, shades of pink, yellow and terra-cotta shades.

Yes. Achillea.
Why do you think you are being a pest?
This is just what GOY loves/does best!

The wild version is Achillea millefolium or yarrow and its a nondescript pinky white colour. The coloured ones are cultivated varieties which are much nicer. Yours looks very pretty.
