Vasha all,
The Poisonous Nettle ground spawn is pretty easy to find. Enter the shroom caves (just cross the bridge from the "newbie" stairs and it's along the wall) and then take a left into a small cave (room, whatever). The Nettle looks like a small bush and it sits along the left wall as you enter.
Good luck to ya.
Udra.
