Abstract
This study was carried out to obtain the basic informations on the flowering habit, pollination patterns and seed setting in Hosta plantaginea Aschers. Flowers came out in the night with white color. Almost fertilization seemed to be out by wind in early and full flowering. But bearing pods by insects and fertilization rate by wind were increased by interval of flowering and particular scent slowly decreased in after flowering. Bearing pods and seeds setting rate were $65.0\%,\;40.9\%$ per peduncle after artificial pollination, and also $33.3\%,\;24.3\%$ in natural pollination, respectively. The flowering times was all around seven to eight o'clock at night and optimum temperature for pollination was $25{\sim}28^{\circ}C$.
