Pickable at: Herbalism Skill 285
First of all, if you want to farm herbs, you need to have Herbalism profession, so visit one of the herbalism trainers. Okay, it is pretty obvious where to farm Sorrowmoss; in Swamp of Sorrows. That’s the only place where it grows post-Cataclysm (The Shattering). So I think there are no more words needed on this subject.
Swamp of Sorrows
This is the only area where Sorrowmoss grows. You don’t need to follow my path, I have drawn this just as an example. You just need to stay close to the water, as you can see the nodes are very close to it.
