Abstract: A support body portion extends inwardly from the top rim of a plant pot and has a substantially vertical channel therethrough bounded on the outer end by the inner surface of the pot, on the inner end by a rod support groove substantially parallel with the axis of symmetry of the pot and on the sides by a pair of side walls that converge radially inward. A plant support rod is positioned in the rod support groove and extends above the pot a substantial distance so that a plant in the pot can be tied to it for support. A spring wedge having a pair of legs, at the same angle to each other as the angle of the slope of the pot side to the axis of symmetry, joined by a resilient bight portion is pushed down into the top of the vertical channel so one leg bears against the sloping wall of the pot and the other leg bears against the support rod to anchor it firmly in the vertical rod support groove.
