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.

1. An adjustable water plant container assembly comprising a weightable base for stable disposition upon a floor of water filled containment means; an elongate, vertically extending supporting column attached on a lower end portion thereof to said base, said column being telescopically adjustable in height above said base and including a first elongate, hollow, cylindrically shaped pipe having a lower end attached to said base; and a second elongate, hollow, cylindrically shaped pipe having an outside diameter less than an inside diameter of said first pipe, said second pipe being at least partially inserted slidably into an upper end portion of said first pipe, said receptacle being attached to an upper end of said second pipe; a receptacle for a water plant or together vegetation being attached to an upper end of said supporting column; an interiorly threaded cap having a circular central opening in an upper surface thereof, said second pipe having an upper end portion which is exteriorly threaded in conformity with the interior threading of said cap, said cap being disposed over and around said second pipe and removably attached to said first pipe, said second pipe containing exterior threading on a base portion; and a confinement ring being threadably mounted on the base portion of said second pipe and being sized to closely and slidably fit within and around the inner wall of said fist pipe. 2. The assembly of claim 1 wherein said base defines a closed hollow interior chamber and a closable access opening to said chamber for use in fitting said chamber with a mass of granulated material to enable said base to rest on said floor in water in a stable manner. 3. The assembly of claim 1 wherein said receptacle comprises a truncated cone shaped pot which is open on an upper end and includes a circular base plate on a lower end from which a collar containing interior threading projects downwardly, an upper end portion of said supporting column containing exterior threading conforming to and threadably joining the interior threading of the receptacle collar. 4. The assembly of claim 1 wherein said supporting column is removably attached to said base. 5. The assembly of claim 1 wherein said base forms an open bowl for filling with a quantity of rocks or pebbles, a lower end of said column being attached to a central collar centrally formed in and projecting upwardly from an inside bottom of said bowl. 6. The assembly of claim 2 wherein said base defines a hollow, cylindrically shaped shaft extending between and opening onto upper and lower surfaces of said base, at least a portion of said shaft containing interior threading, a base portion of said supporting column being exteriorly threaded in conformity with the interior threading in said shaft, said base portion being removably disposed in and threadably engaging the threading of said shaft. 7. The assembly of claim 6 wherein said chamber annularly extends about said shaft. 8. The assembly of claim 1, further comprising a compressible, resilient gasket being tightly disposed in an upper interior end portion of said cap and having a diameter sized to fit closely against an interior sidewall of said cap, said gasket also defining a circular central hole therethrough through which said second pipe extends in a close but slidable relationship when said cap is loosely threaded upon said first pipe such that said gasket is in a relaxed, uncompressed state, said gasket is being adapted to tightly and non-slidably grasp said second pipe when said cap is tightly threaded ton said pipe such that said gasket is placed in a compressed state.
