>>2728344>You can tell it is Giant Hogweed by the size of it.That's completely false. The pic is me with a hemlock stem that was over 3m tall.
Noticeably higher specimens grew nearby on a steep river bank, I did not risk falling down for a better photo.
Telling people that the size is a good way to tell apart giant hogweed is just conning them.
Giant hogweed grows only basal leaves for the first few years, and while the leaves are huge, the plant is usually not taller than its surroundings.
Only on the final year it grows a stem, flowers, spreads seeds and dies.
