When do peonies bloom in a day
Compared to the common knowledge of when peonies bloom in a day and the green plant maintenance tips about the blooming season of peonies, here is a detailed introduction.
【When do peonies bloom】Generally, peonies bloom singly at the top or near the top of the stem or in the axils of the upper leaves, and there are also some rare varieties that bloom with 2 or 3 flowers together. The blooming period is from May to June.
Generally, peonies bloom singly at the top or near the top of the stem or in the axils of the upper leaves, and there are also some rare varieties that bloom with 2 or 3 flowers together. The original species has white flowers, with a diameter of 8 to 11 centimeters, 5 to 13 petals, obovate in shape, many stamens, yellow filaments, a shallow cup-shaped flower disc wrapping the base of the carpels, with a rounded tip, carpels 3 to 5, hairless or hairy, with a beak at the top; garden varieties have a rich color palette, including white, pink, red, purple, yellow, green, black, and bicolors, with flower diameters of 10 to 30 centimeters, petals can reach up to a hundred or even 880 in some varieties, and the flower shapes are diverse. The blooming period is May to June.
Main factors affecting peony blooming
(1) Temperature: In the same area, the blooming time of peonies is closely related to the temperature changes in spring. Temperature can affect the entire blooming process. A warm or cold spring can result in a difference of 4 to 5 days to even 10 to 20 days in blooming time.
(2) Water and rainfall: Water and rainfall have little effect on the blooming period. Ample watering before blooming or encountering rainfall can help peonies bloom, making the flowers large and the colors bright; however, if heavy rainfall occurs, the flowers will be damaged and may wither prematurely. If the soil moisture content is low before blooming, the flowers will be smaller, the colors less vibrant, and the blooming period will be shortened.
(3) Altitude: Altitude can affect changes in temperature, light, and humidity, thus affecting the blooming period. Generally, as altitude increases, the blooming period is delayed. For example, peonies in Luoyang finish blooming on May 14, while on the Baiyun Mountain near Man County, the peonies are just beginning to show color. In Pengzhou City, Sichuan, the peony blooming period is ending, while on the Danjing Mountain nearby, the flowers are just beginning to open. Different altitudes in cultivation areas can be used to extend the viewing period.
(4) Light: Light often accompanies temperature in affecting plant growth and development and blooming period. Insufficient light before blooming can affect flower color, making it less vibrant, while strong light during the blooming period, combined with higher temperatures, can shorten the blooming period or burn the flowers. Therefore, setting up a sunshade during the blooming period can extend the peony's blooming time.
In the northern regions, peonies sprout from the ground from the end of March to early April. The buds formed in the root neck in June to July of the previous year, after growth and floral bud differentiation, sprout from the ground when the spring temperatures rise. The buds are mostly beautiful purplish red, with a few varieties being tender yellow-green, and they have high ornamental value. After more than 20 days of rapid growth, the new stems can reach about 2/3 of the mature plant height, the lower leaves are flat, and the young leaves are also purplish red or yellow-green; after the lower leaves flatten, they grow rapidly, and flower buds appear at the top of the stems in early April; after the buds appear, with the stems and leaves becoming full, the flower buds develop, and the flowers start to bloom in mid-May; by early June, the blooming period ends. A single flower blooms for 5 to 7 days, with single-petal varieties blooming for a shorter time and double-petal varieties for a longer time. The group blooming period (from the early blooming varieties to the late blooming varieties) is about 25 days; after the flowers fade, mixed buds differentiate and develop in the underground root neck; seeds mature in August, and by the end of October to early November, the above-ground parts die, and the mixed buds on the root neck overwinter in the soil, sprouting and growing again the following spring.
The life cycle and annual cycle of peonies
Peonies are perennial herbaceous plants. From seed germination to death, they go through the processes of growth, flowering, fruiting, aging, and death in their life activities, which is called the life cycle, also known as the major development cycle. For seedlings, the life cycle can be divided into three developmental stages. Seedlings usually bloom in about 4 years, with the juvenile period before flowering. In the first year after sowing, the plant is 3 to 4 centimeters tall, with 1 to 2 leaves, and the root is 8 to 10 centimeters long, with the upper part being thicker, about 0.4 to 0.5 centimeters in diameter; in the second spring, the plant can reach a height of 7 to 8 centimeters, with better growth reaching 15 to 29 centimeters, and a plant spread of about 30 centimeters; in the third spring, a few plants have already bloomed, with a height of 15 to 60 centimeters, only one main root developed; the plant spread is 30 to 40 centimeters, and by the fourth year, all plants can bloom. After entering the adult stage, the growth is vigorous, the flowering is abundant, and it is in the best ornamental period. As long as the environment is suitable, the adult period can last for 20 to 30 years, then entering the aging period until death. Divisional seedlings directly enter the adult stage and gradually age after 20 to 30 years.
The annual cycle, also known as the minor development cycle, refers to the阶段性 developmental changes of the peony plant throughout the year, following the changes in the climatic rhythm. It mainly manifests as the alternation of the growing period and the dormant period. Among them, the vernalization stage of the dormant period and the light stage of the growing period are the most critical. The vernalization stage of peonies requires a temperature of 0°C for about 40 days to complete, after which the mixed buds can sprout and grow. Peonies are long-day plants, and the flower buds need to develop and bloom under long-day conditions. After the mixed buds sprout, if the light time is insufficient or under short-day conditions, they usually only grow leaves and do not bloom or bloom abnormally.
