Hey fellow WoW players! Welcome to my blog and this article about farming Rain Poppy. There is no need to ever buy it on AH if you follow my guide. Quite the contrary, you can even farm it to sell on Auction House and earn lots of gold this way.
If you have hard time earning gold in WoW I recommend using this in-game add-on, called Zygor Guides. It really helps you with lots of aspects in the game, including Farming, Crafting, Gathering, Auction, Leveling, Professions and much more... Though, the add-on costs some money, but is well worth the price. They also have a FREE TRIAL you may want to try.
Rain Poppy mostly grows in The Jade Forest. It can also be found in the Vale of Eternal Blossoms but in much smaller quantities.
The Jade Forest
Note that it grows near water sources.
