It is achillea, there are many that are nice garden plants, multipling around from runners and stays in a clump. There is a new variety on the market, and it is a reseeder, just horid cuz is just keeps going all over the garden. I got rid of mine and have kept the clumpers. It is an herb and can be made into a tea.
Daucus carota is Queen Anne's Lace, pix below of the taller variety which is a biennial. I love it, yes it does reseed but easy to pull. Lightly fragrant, blooms in late spring.
1.Daucus c. , this one is 6 foot tall..., and there is also a roadside one at 12"
"Orchidfancy" has a plant in her front yard that looks like Queen Anne's lace and it is so beautiful. She called it Orlaya.. Look up that flower and see if it looks like the mystery plant. When I first saw my friend's, I thought it was QA's lace too. Such a striking flower and delicate looking.
