The terrible flowers you and Mithrandir encountered in Imlad Morgul have sprung forth anew and now spread beyond the valley of the Dead City.
'${PLAYER}, grim tidings have been delivered to me by one of Aragorn's rear scouts. The noisome flowers we burned within Imlad Morgul have grown anew and now spread beyond the shadowed vale.
'They cannot be allowed to spread beyond Imlad Morgul, else the lands of Ithilien may also succumb to their taint. If flame cannot hinder them, I fear that we may leave behind greater troubles for Gondor.
'I would ask that you return to the border of Imlad Morgul and burn them once again. If they return again, it seems our only course shall be to continue pruning them.'
Noisome flowers can be found along the road into Imlad Morgul.
Mithrandir has asked you to return to the border of Imlad Morgul and cull the noisome flowers that have begun to spread into Ithilien.
Mithrandir can be found at the Camp of the Host on the border of the Wastes far to the north in North Ithilien.
You have burned the noisome flowers outside Imlad Morgul, and you should now return to Mithrandir with news of your success.
