It is made up of a plant-retaining wall portion formed by arcuate segments that abut one another, a holder being provided to releasably lock the segments in firm abutting relationship, this holder including locking strips that are provided outwardly of the wall segments, each strip having a groove at its lower end. The pot further includes a saucer portion for holding the wall portion. This saucer portion has an upstanding peripheral skirt and a series of horizontal thread portions projecting inwardly from the skirt and capable of being snugly received into the grooves at the bottom of the strips so that the wall portion may be held firm in the saucer portion. These thread portions are spaced from one another a distance sufficient to allow the strips to be inserted therebetween prior to be rotated for engagement of the thread portions into the grooves.
