Leek Seed

The Leek Seed is a seed added by Pam's HarvestCraft, which grows into an Leek Plant on Farmland. When broken, it will drop nothing. However, when right-clicked, it will drop 1 Leek (or 1-2 Leeks before version 1.8.9a) and the crop's growth will go back to its pre-mature form. Bone Meal may cause the crop to grow one stage, just like regular Vanilla crops.

Recipe
Leek Seeds can also be obtained from the Shaded Garden (or from the Leafy Garden before version 1.8.9a) or from breaking Grass if configured.
