It must have a flower and a name

Same thing going the other way. I bent over looking for that weed with the stiff hairy trunk, able to wind its thin head out, one of the highest points in the garden. I gave everything to looking up--easier to spot the head than the base where the earth was soft, the roots easily pulled clear. Must have been a rock convention not long ago, these stones I launch over the fence. Ting one of them clips the top.
