Abstract: An artificial representation or simulation of a plant having stalks or stems in a cluster radiating upwardly from a common point at the apex of a main stem, for example, as in an umbel, is composed of a plurality of stem-defining members each molded of plastic to have respective co-planar stem portions arising from a collar which is engageable on the apex portion of the main stem, and at least one of the stem-defining members has a configuration to position and maintain the respective stem portions in a plane angularly displaced from the plane of the stem portions of each other stem-defining member. Preferably, at least one of the stem-defining members has at least one bifurcated or tined projection extending outwardly from its collar to embrace a stem portion of another of the stem-defining members when the collars are arranged one above the other on the main stem.
