Dragon Grass is a plant that is a panacea for wind drakes, but deadly poison to humans. Spoiler warning: Plot and/or ending details follow. (Skip section) In Bartz's World, dragon grass grows at the summit of North Mountain. Lenna's wind drake, Hiryu, flies there after being wounded and separated from King Tycoon, but the dragon grass is surrounded by poisonous flowers. Lenna crosses the field to retrieve it, and the plant heals Hiryu (who then heals Lenna of the poison). Spoilers end here.
