I continue to have a hunch that plant B is some form of Bidens, but I
open to better suggestions. For what it's worth, the leaflets of plant B
do look somewhat similar to the leaves of Guizotia, but they're broadest
near the base, not past the middle.

Thanks for your extensive analysis Stewart - remarkable. So ... "the
hunt goes on" :-) We won't be grubbing them up and composting them any
time soon.


PS: as for the size of the plants and the seeds, Epilobium hirsutum
seeds are smaller.

Well yes -- I was joking :-) I always think for foxgloves, and even
more the Great Mullein, which are whacking sturdy plants!

Cheers
