Cinnamon

Cinnamon is a tree growing spice found in Warm biomes. Cinnamon is one of three "log fruit" trees including Maple and Paper Bark. This means the whole trunk produces, instead of the leaves.

Farming
Right-click on the trunk when it is ripe to get Cinnamon. Applying bone meal or fertilizer will cause the trunk to ripen faster.

Combining three Cinnamon with any vanilla sapling creates a Cinnamon Sapling. Cinnamon Sapling is also available for purchase from The Market.

Ground Cinnamon
Ground Cinnamon is created using Cinammon with the Mortar and Pestle (renamed Grinder in Harvestcraft 2).
