For thousands of years, peony and peony have been called "two unique". Some people say, "Peony is the king of flowers, and peony is the phase of flowers." Peony and peony are like twin sisters, so many people will confuse them. In fact, peony and Paeonia belong to Ranunculaceae and Paeonia.
The leaf tip of peony often divides again; The leaf tip of Paeonia lactiflora is pointed and no longer divides. This is the easiest way to distinguish two kinds of flowers. Peony leaves are wide, the upper surface is green and slightly yellow, the peony leaves are hairless, and the lower surface has white powder; Peony leaves are narrow, shiny and dense.
Extended data
Peony is a deciduous shrub. The stem is 2 meters high; The branches are short and thick. The leaves are usually bipinnately compound, and occasionally the leaves near the top of the branches are 3 leaflets; The terminal leaflets are broadly ovoid, 7-8 cm long and 5.5-7 cm wide, 3-lobed in the middle, the lobes are undivided or 2-3-lobed, the surface is green, hairless, the back is light green, sometimes with white powder, sparsely pubescent or nearly hairless along the veins, and the petiole is 1.2-3 cm long.
Lateral leaflets narrowly ovate or oblong-ovate, 4.5-6.5 cm long and 2.5-4 cm wide, ranging from 2-lobed to 3-lobed or undivided, subsessile; The petiole is 5- 1 1 cm long, and the leaf axis is hairless.
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. After the mixed buds germinate, if the light time is insufficient, or under the condition of short sunshine, they usually only grow leaves, and do not bloom or bloom abnormally.
