The cultivation of P. virgata for cut flowers or cut foliage is currently restricted by propagation difficulties. In SE Queensland, stems of P. virgata are commercially harvested all year round from natural populations and sold on the domestic and export flower market. Propagation has been studied using seeds and cuttings. Seed germination of 50% can be achieved by fermenting the fruits, removing at least half of the endocarp, and culturing in an aseptic environment. Cuttings will root when juvenile material, of selected genotype, is used. IBA concentration in the rooting powder used and the season of propagation appear to be important factors and these are being studied. The prospects for commercial production of P. virgata appear promising.
