Minecraft wiki entry for Bone_Meal, associated text: If bone meal is used on a grass block, 0–8 tall grass, 8–24 grass and 0–8 flowers form on the targeted block and on random adjacent grass blocks in an 8×8 area centered on the southeast corner of the targeted block.[verify] The flowers that appear depend on the biome, meaning that in order to obtain specific flowers, the player must travel to biomes where the flowers are found naturally. See Flower § Flower biomes for more information.
