Abstract: A vertical wall display system for displaying potted plants includes trays that have a base portion and a back portion disposed at an acute angle with respect to each other. The base portion of the tray defines a plurality of niches in a linear array for receiving potted plants, each niche defines a reservoir capable of retaining a predetermined volume of a fluid. The back portion of the tray includes connecting elements for connecting the back portion of one tray with the back portion of a second tray so that the trays are substantially co-planar. Each of the trays define at least two sections that are joined so at to be separable into discrete sections that include different numbers of niches.
