The Camellia japonica species was used as a landscape tree. It is expected to be useful as a landscape because it has evergreen leaves and flowers. This study was intended to identify different root ability by the aspects of cutting collection, water sprouts and general stem growth cutting, number of leaves and soil medium. The results of this study are as follows, 1. Appearance rates of adventitious roots are different depending upon the location of collection. The appearance rates of cuttingc collected in eastern parte were3.3% western parts 25.%, southern parts 10.0% and in northern parts 8.4%. 2. Appearance rates of adventitous roots of cuttings collected on leaf bud cutting is 80.0%, and stem cutting is 43.3%. 3. Appearance rates of adventitious roots of cuttings collected on water sprout stems were 81,7% but in general cases 40.0%. 4. Appearance rates of adventitious roots of the water sprout stems on the one-year stem was twice faster than that of the two-year stem. 5. Adventitious rooting rate increased in proportion to the number of leaves. The maximum rooting rate happened in case of two leaves, whereas the minimum rate happened in case of ½ leaf. 6. The rooting rates were different depending upon soil medium. It was low in a case of single medium with vermiculite only but significantly high rooting rate as observed in a case of mixed medium with vermiculite and perlite or perlite and peatmoss.
