Abstract
Based on the study of its habitat in Hyogo Prefecture and experiment cultivating and sowing the plant, this paper reveals the phenology of the vulnerable plant species Potentilla discolor Bunge. As the result of this study, it is the polycarpic perennial that hasn’t been dormant and when new leaves emerged immediately after mowing. When the rhizome is separated, it formed individuals by vegetative propagation. Sowing and cultivating experiment, germination are three times, June to July, September to October, May to April from next Spring. By the phenology, the proper management for leafing and germination time is the most effective management method.
