In a year, the periodic development changes of Paeonia lactiflora plants with the change of climate rhythm mainly show the alternating changes of growth period and dormancy period. Among them, vernalization stage in dormancy period and illumination stage in growth period are the most critical. The vernalization stage of Paeonia lactiflora needs to be completed at 0℃ for about 40 days, and then the mixed buds can germinate and grow. Paeonia lactiflora is a long-day plant, and its buds should develop and bloom under long-day sunshine.
