The present invention relates to a prefabricated multifunctional flowerpot assembly, and a flowerpot and a support provided thereto, and more particularly to, a prefabricated multifunctional flowerpot assembly capable of performing an air purification function as well as an indoor humidification function by photosynthesis reaction which is attributed to a lighting apparatus, if particularly used indoor, and an automatic water supply function indoor and outdoor, having a storage tank storing water, a flowerpot, a support supporting the flower pot, and the lighting apparatus that may be freely assembled in various shapes to be applied at a necessary place as appropriate, and being applied in an eco-friendly manner. According to the present invention, the flowerpot assembly comprises: a flowerpot receiving culture soil and having a protruded joint pipe formed therein to allow excessive amount of water supplied therein to overflow to be drained when water is oversupplied than a predetermined water level, and having an adsorption member absorbing water and a ventilation member not absorbing water but having air permeability to allow external air therein and a lighting box provided in a frame shape, having an opaque or transparent partition member provided to a frame to receive the flowerpot inside the frame, and a lighting device emitting light to the outside of the partition member. The joint pipe is protruded inward the flowerpot by a predetermined height as well as in a lower direction outside the flowerpot, at the same time. The lower part of the joint pipe is connected to a drainage hose which allows excessive amount of water greater than the level of an internal protrusion length of the joint pipe to overflow to be drained, when water is supplied to the flowerpot. The flowerpot comprises an insulation material provided on an inner circumferential surface thereof and an anti-freezing member provided around the joint pipe inside the flowerpot.COPYRIGHT KIPO 2016본 발명은
