The present invention concerns a device for supporting flower pots at a variable distance from each other, of the type comprising a plurality of receiving units (2) disposed in a same horizontal plane (9), each of the said receiving units being able to receive and support a flower pot, characterised in that the said receiving units (2) are carried by at least two parallel girders (3a, 3b) connected to each other by at least two slides (4a, 4b) in such a way as to define a channel (5) of variable width between two adjacent girders (3a, 3b), each receiving unit (2) being integral with a single girder (3a, 3b) and the said receiving units being regularly spaced along the said girders (3a, 3b). <IMAGE>
