The Plain Seed is one of the Items in the Pokémon Mystery Dungeon series. Other than filling up the belly of the Pokémon by 5, it has no special effect. The only means of getting the Item is to use up a Reviver Seed and the seed will convert into a Plain Seed. However, this can only be done by a Pokémon with an Item Master IQ Skill. It is not available in any shop, however it can be sold for 1 Poké Coin.
