Where I come from, it's important to know which plants are poisonous, which aren't, and how you can harvest what you need of something without irreparable harm.

[ Whatever does grow in Faerghus, the last thing anyone wants to do is kill the plant off when gathering anything from it. ]

Like how mushrooms grow back quickly if you don't damage their root structures. Ever the better if you can help make their surrounding conditions more ideal. More of a trade then, you could say.
