PURPOSE: A flowerpot support for a partition is provided to be conveniently mounted on the partition without using separate tools or a fixing device, by insertion-combining a main support stand, where the flowerpot support is combined, into an upper end part of the partition using elastic force in an insertion method.CONSTITUTION: A flowerpot support for a partition comprises: a main support stand(100) which is insertion-combined to an upper end part of the partition a flowerpot support stand(200) which is combined to the upper surface of the main support stand and a storage support stand(300) which includes a vertical combining part(310) combined to the front face of the main support stand, and a horizontal mounting part(320) combined to the lower end of the vertical combining part. The main support stand comprises: a horizontal support which is horizontally arranged in order to be coupled to the upper end of the partition and a front support stand(101) and a rear support stand(103) which are curved-cut and formed downward in the front and rear ends of the horizontal support stand respectively. The front and rear support stands are elastically curved-cut to the direction in which at least one of the front and rear support stands has a slope so that the mutual distance becomes closer downward, in order to be elastically and tightly coupled to both sides of the partition. A flowerpot is installed with a flowerpot fixing module inside in order to support and fix the flowerpot mounted on the flowerpot support. The flowerpot fixing module comprises fixing blocks which are mounted so as to be able to move linearly to the mutually facing direction within the flowerpot support, and elastic springs which apply elastic force to the fixing blocks so that the fixing blocks move to the direction in which the fixing blocks come close. A hook is formed in the front support stand of the main support stand. A trapping slit hole which is insertion-combined to the hook is formed in t
