Planting of peony, a perennial herb is usually planted in fall but the planting time can be postponed to next spring for other benefit such as land use, labour diversification and etc. This study was carried out to know the effect of planting time in spring on growth and yield of peony. Sprouting date in first year growth was earlier as planting time was later. Planting on March 10 showed best both top part and root growth and planting after that time resulted in worse growth. In planting on April 10, missing plant rate was 24% and accordingly root yield decreased to 43% comparing with that of March 10. Planting on March 10 resulted in thick and large number of root and so yield per l0a was 635 kg, the highest value among the other planting time in spring. The paeoniflorin content was not different significantly by planting time. These results suggested that March 10 was most appropriate for planting time in spring.
