The Cherry Blossom event celebrates spring and occurs from March 30 to May 4. During this time one can sometimes gather Cherry Blossom Seeds from Wild Herb, Dry Desert or Dry Thicket resource spots in the world. Cherry Blossom Seeds can be used in Farming and the resulting Cherry Tree yields Unwithering Cherry Petals which can be exchanged at Hunt, the Seed Vendor in Heidel or Ahr in Calpheon.
For 10 petals one obtains a Cherry Blossom Pot that can be placed into your residence for 20 Interior Points. Thirty Petals gives a Cherry Blossom Earring.
