Eco friendly wedding favors

I am trying to keep my wedding as Eco friendly as possible.  With that being said, I would love some help coming up with Eco friendly wedding favors. I have seen succulents and giving different herbs and whatnot. I want something more original though. I was thinking of giving away seeds? But I'm still trying to figure out how to make that not weird. I also don't want to look cheap. Any ideas??
