It's growing in the rockery, totally the wrong place but I like the tallness of it. Tiny pink flowers form along the top 1/4 of the 3-4ft stem. The leaves form a low 8-12 inch mound.
Francoa, probably F. sonchifolia .
I searched Francoa sonchifolia .and it is one. Thankyou very much DW.
Great plants. A good do-er.
