Abstract A stand, particularly intended for Christmas trees having means to secure the tree in a water container and means to enable said water container to take various positions of inclination, thereby greatly facilitating both support and correct alignment of the tree in a vertical position. Retaining means, such as clasps, are provided to secure the tree trunk in the water container, and a ball joint is provided to permit adjustment of the alignment of the water container relatively the base supporting said container. The ball joint outer concave portion comprises two sections, one rigid section and one movable relatively the first by means of an eccentric shaft operated by an actuating lever.
