A height adjustable support assembly for a receptacle in which a water plant or other vegetation can be grown is disclosed. The assembly includes a base which can be weighted down with granulated material such as sand or pebbles, a two section, telescopically adjustable, elongated supporting column attached on a lower end to the base, and a receptacle attached to an upper end of the supporting column. In one embodiment, the receptacle is fitted with a flotation collar so that it can float on the surface of the water containment means in which the assembly is disposed as the water surface level changes, carrying with it an upper section of the supporting column. In another embodiment, the height of the supporting column and receptacle can be incrementally adjusted and fixed by means of a retaining pin. In yet another embodiment the supporting column height can be adjusted and fixed by means of a threaded cap containing a compressible gasket. Means for stabilizing the alignment of the upper section with a lower section of the supporting column is also disclosed.
