Take the Seed Voucher to Bashana Runetotem in Thunder Bluff.
With what we call an Evergreen Pouch, we have cultivated Tharlendris seeds in the soil from Un'Goro Crater. These seeds have blossomed into an array of random, potent herbs. One result is morrowgrain, a mysterious herb we know little about; I very much hope to unravel this mystery for the Circle.
Take this voucher over to my daughter Bashana, and she will give you some seeds so you may assist us. If you run out, you will need to purchase more from her.
