Have you ever been stuck in a cave starving with only a few mushrooms. Chased at night by mobs with your hunger approaching low? Now, with edible plants, you'll be able to eat any plant in the game and escape your death by hunger. Vanilla plants that serve no to very little service are currently the only plants available to eat. Modded plants may arrive in the future but don't hope on it.
