Abstract: An integrally molded plant pot for growing a plant which has a base portion and a plurality of flap portions connected to the base portion, each having a plurality of perforated penetrating holes. The base portion is surrounded by the flap portions. The flap portions are assembled by means of a clamping portion provided on a side edge thereof. The flap portions are economically designed to be molded in an injection molding machine or the like, so that they can be opened outwardly at a bending portion provided at the bottom surface of the flap portions. The pot has a strength and a flexibility sufficient to make removal of the plant therefrom easy during transplantation from the pot.
