Abstract: A receptacle for growing plants includes a pot and a bowl-shaped inset piece or liner disposed in the pot. The floor of the pot has a plurality of upstanding tubular projections each having a passage open to the underside of the pot ands closed at its upper end. This arrangement allows simple and secure attachment of casters, feet, or other supports to the underside of the pot without destroying the aesthetic appearance of the pot itself. Various other projections and tubular members serving various technical purposes can also be provided in a similar manner without destroying the aesthetic appearance of the receptacle. The inset piece is adapted to conform to and cooperate with the projections and technical devices provided for a particular receptacle.
