Olearia scilloniensis is an evergreen shrub with high ornamental potential. With the aim to establish a complete multiplication method, propagation trials have been carried out testing the physiological stage related to season and several growth hormone treatments. Trials were made in January, April, June and October and the effect of the auxins IBA, NAA and a synthetic water-soluble auxin, K-IBA, was evaluated on rooting percentage, related to controls and a commercial powdered mixture. The role of the agent in which the hormones were dissolved was also discussed. In January-February, during anthesis, the plant showed the highest rooting performance when the floral buds were excised. The presence of the flowers strongly inhibited the rooting process. So the best period for vegetative propagation by cuttings was from January (96,6 %) to April (62,8 %). During the period with a low natural rooting potential (June to October) significant increase of rooting percentage (near to 50 %) was obtained only with the treatment with the commercial product Rooting® containing NAA plus IBA, 200 ppm each. With these results, the propagation of this plant could be performed with high efficiency and a possible commercial value.
