The message
from "Franz Heymann" contains these words:

[(Alleged) giant hogweed]

Mine is approximately 7 ft if left undisturbed. And yes, the reason why we
have to eradicate it is because neither my wife nor I can get near it
without skin problems. (Plus the fact that it chose to make its home bang
in the middle of a little group of potentillas).

It doesn't sound like giant hogweed to me then unless it's on really
very poor ground, the sod will grow to ten or twelve feet without even
trying.
