Snow Lily farming
I made this Snow Lily farming guide to help out players who want to farm the herbs instead of buying them from the Auction House. You can pick this Herb from skill 1, but you will only get [Snow Lily Petal] until you reach Herbalism skill 480-520 (10 makes one herb). Keep in mind you will not have access to flying mounts until you reach level 90, so you won't farm Snow Lily that efficiently before you reach level 90.
This herb grows at snow-covered areas and only Kun-Lai Summit has those, so basically this is the only zone where you can farm Snow Lily. You will find a few caves in the mountains, but I only recommend to go into the caves if you have some kind of sprint/stealth ability, or if someone else is farming in the zone.
