Un'Goro Soil

Un'Goro Soil could be found in Un'Goro Dirt Piles on the ground in Un'Goro Crater. It also drops off several mobs there.

• Un'Goro Soil (quest)
• Morrowgrain Research (Alliance, 2)
• Morrowgrain Research (Horde, 2)
• Bungle in the Jungle

Combining two Un'Goro Soil samples and a Packet of Tharlendris Seeds in an Evergreen Pouch yields an Evergreen Herb Casing. The herb casing yields one of several herbs, often Morrowgrain, an item used in a couple repeatable quests to gain reputation with Thunder Bluff or Darnassus.
