Chimonanthus praecox L. is an ornamental tree species originating from Chine. Its yellow coloured, fragment flowers appear during winter, usually from November till February. Propagation and introduction of this species would increase the diversity of ornamental trees in parks in Serbia. Propagation was performed using cuttings of top branches containing one or two internodes. Two propagation methods were employed. In the first cuttings were collected 4 times (June 21st, July 8th and 24th and August 8th) and their basal ends were briefly dipped in powder containing 0.8% IBA/ Cuttings were placed in a glasshouse and rooting parameters were scored after 6 weeks. The highest rooting percentage (37.3%) and the best development of root system was obtained in cuttings collected on July 24th, In the second approach cuttings were immersed 24 hours in solution containing 20 or 50 mg/l IBA. Cuttings were planted on June the 7th. Rooting percentage in cuttings treated with 20 mg/l IBA was 11.1% and 23.9% in cuttings treated with 50 mg/l.
