A plant container comprises an inner wall (1) providing a pot for a plant (24) and an outer wall (2), between which is provided a water reservoir (8). The reservoir replenishes water in a dish (3) through an opening (19), and as water is sucked out of the dish by the plant, the opening (19) and a vent pipe (22) are uncovered to release a vacuum in the reservoir and allow replenishment of the dish from the reservoir until the outlet and vent pipe are reclosed by the water in the dish.
