White Leaf Seeds are the type of Seeds which should be grown for Quests. They should be grown into White Leaves during the Bob The Farmer quest. They also require 100 Bonemeal to be planted.
Growing these seeds may be especially difficult, as they can die very often even with high Farming levels. As the tooltip suggests, anti-disease potions can help reduce the chance of death, but specific death rates are not available.
