Garlic are plants which can only be raised in Any Gardening Pot. Garlic can be replanted just like other Potable Plants. Although this may be less efficient than trying to use a Sprouted Garlic Clove, you don't need to wait for it to sprout.
If you do not already have a Garlic plant to place in a pot you will instead need to plant a Wild Garlic which has a random chance of resulting in a Garlic instead of a Wild Garlic.
Six Garlic can be used to craft a Garlic Braid inspirational.
