|Ore dictionary name||seedOnion|
The Onion Seed is a seed added by Pam's HarvestCraft, which grows into an Onion Plant on Farmland. When broken, it will drop nothing. However, when right-clicked, it will drop 1 Onion (or 1-2 Onions 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.
