The purpose of this study was conducted to obtain the basic information on the high nursery stock of Hibiscus syriacus. Seedling and pinching effect of the results obtained could be summarized as follows : Plant height was increased along with plant age became older and Chiu cultivar was higher than Yunok Cultivar. Seedling propagation was higher than cutting propagation and pinching propagation was higher than nonpinching. Pinching after seedling propagation showed the highest values in 3 years old trees by 186.7cm. Stem diameter was increased along with plant age became older, but internode length was decreased along with plant age became older.
