A support structure is configured to be pierced by stems of flowers to hold the flowers in place and to retain moisture. The support structure extends along a longitudinal path and has front and rear surfaces and two opposite side surfaces. A backplate overlies the support structures rear surface. A frame overlies the support structure and is attached to the backplate to hold the support structure against the backplate. The frame includes longitudinal bands that extend along the longitudinal path along the support structure. The frame further includes cross bands that extend about the support structures front and side surfaces in directions that are perpendicular to the longitudinal band. Each cross band crosses the longitudinal bands at crossing points at which the longitudinal band is perpendicular to and adjoined to and underlying the respective longitudinal band.
