Please help identify tall hollow stemmed plant.

Hi.
Firstly apologies for initially posting about these plants in the general food section. Have just found the right place.
Oops.
These plants are in my new tort enclosure, but I'm scared to put my hermanns out because am not certain whether safe.
I sowed a lot of seeds including alexanders when I built the new pen, but they don't quite match the pictures and I am worried that they could turn out to be hogweed or water hemlock or some other poisonous plants.
Any help on this gratefully received.
Thanks
Rose

Hi Rose:

Chances are pretty good that it's something that came in the package you bought. I would pull up one of them and take it to a plant nursery for identification. Sorry, I don't know what it is.
