Sugar Canes is an item added by Vanilla Minecraft. Although Sugar Canes grow up to 3 blocks tall, reportedly sugar cane has been seen to have been generated up to seven blocks tall. Sugar canes will only grow when planted on Grass, Dirt, or Sand adjacent to Water on at least one side horizontally. The primary uses of sugar canes are to make Sugar and Paper.
Sugar Canes can be used to craft the Punji Stick from Tinkers' Construct, Paper, and Sugar, meaning it is a necessary material for creating Cake, Pumpkin Pie, and Enchanted Books (which are rendered obsolete by the Enchanting Plus mod).
