What are the opening hours of various flowers?

Clocks and watches bloom at 24 o'clock, and most flowers bloom during the day, in the morning or evening. ?

There are also before dawn, and there are very few in the middle of the night. Generally speaking, insect-borne flowers bloom most during the day because of the need of pollination. ?

However, the opening hours of various flowers are different. The order within 24 hours is: morning glory at 4 am, wild rose at 5 am, Long Kuihua at 6 am, peony at 7 am, lotus at 8 am, Scutellaria barbata at 10 in the morning, purslane flower at 12 in the morning, sunflower at 15 in the morning, and morning10.

Note: Due to the weather, the opening hours of various flowers may change.

Knowledge expansion at flowering stage;

In nature, plants have a certain circadian rhythm. It is controlled by biological clock, which may control the biochemical activities such as flower opening, fragrance and nectar production, root juice secretion and leaf dormancy. Inflorescences can be opened to attract pollinators who are active at different times, such as plants that bloom during the day, to attract bees, butterflies and birds; Plants that bloom at night attract moths and bats. ?

Many plants bloom and close regularly, which seems to tell people the time of day. The elegant dandelion blooms around 5 am and has been called "the shepherd's clock" for centuries. The star of Bethlehem blooms around 1 1 and gets the reputation of "1/princess". Brahmin ginseng blooms at 4 am and closes at noon, which is called "John's lunch break". At dusk, night grass and Amazon Wang Lian open one after another; Chinese rose quietly unfolds its petals in the evening 10, and Ye Xiang cactus doesn't reveal its fragrance until midnight. ?

The earliest scholar who discovered the physiological rhythm of plants was Swedish naturalist Linnaeus, who observed the fluctuation of flower opening and closing in some plants. Linnaeus divided 46 kinds of plants with fluctuating habits into three groups: one group is atmospheric flowers, whose opening and closing changes with atmospheric conditions; One group is tropical flowers, which change with the length of light; There is also a group of bloom flowers falling regularly, regardless of the length of day and night. Linnaeus planted the third group of flowers in flowerpots, and then put them on the desk in the morning and evening order, which became a "flower clock" full of natural interest. ?

There are different flower clocks in different areas. Flowers and plants that bloom at different times in the same season can form different "flower clocks". ?

In our country, the snake twist blooms at the earliest in the morning (around 3 o'clock), and at around 4 o'clock, the big horn of the morning glory also opens; Then wild roses bloom (around 5 o'clock) and Long Kuihua opens (around 6 o'clock); Next, beautiful and elegant tulips (about 7: 30), Scutellaria barbata (about 10) and Euphorbia macrophylla (about 1 1 0) are in full bloom, and afternoon flowers (about 12) are in full bloom under the scorching sun. After noon, marigold blooms (about 15 o'clock), mirabilis jalapa (about 17 o'clock) adds fragrance, and tobacco flowers bloom (about 18 o'clock). As night falls, the moonlight flower (about 19 o'clock) sprouts, and the cordate telosma (about 20 o'clock) sprouts to welcome the dawn. ?

Common flower clocks in Europe and America are composed of 65,438+03 kinds of flowers: striped cat ears bloom at 6 o'clock, African marigold blooms at 7 o'clock, Zi Yuan of mouse ears blooms at 8 o'clock, Sophora alopecuroides blooms at 9 o'clock, papillae plants bloom at 65,438+00, Bethlehem Star blooms at 65,438+065,438+0 and suffering flowers bloom at 65,438. Stellaria sonchifolia was collected at 14, Sayuri at 15, Inula at 16, Lilium multiflorum at 17, and cordate telosma at 18. ?

Timekeeping Garden has a long history and had a glorious era. In ancient times, China people first designed a timed garden, that is, plants that could completely indicate the time of day were planted in a garden. In Europe, the Roman Empire and Charlemagne's time gardens, marble sundials, brass sundials or water clocks were placed in the gardens, but the flowers themselves could not show the time. /kloc-at the end of 0/6, an old-fashioned flower clock was built in Peterhouse College, Cambridge University, England. Its Roman numeral 12 is simulated by trimmed boxwood shrubs, and the pointer is made of yew with its branches cut off. In addition to Roman numerals, flowers are planted that open or close at corresponding times, which can accurately reflect the time of day. ?

The first garden modeled on modern clocks was the street clock garden in Edinburgh, Scotland. The diameter of the "round clock" is about 4 meters. Its pointer is made of hollow metal and driven by machinery. The Arabic numerals 12 on the "clock face" are modeled by planted flowers, which is not only realistic in modeling, but also accurate in walking. ?

"Flower Clock" has been popular in cities and gardens in many countries in the world since then, and it is artificially dressed to beautify the city. There is a huge "flower clock" by Lake Lemmon in Geneva. The mechanical structure is installed underground, and the clock face on the ground is a colorful pattern composed of flowers. There is also an hour hand and a minute hand on the clock face, which can indicate the time like an ordinary clock. The flowers on the clock face change with the seasons, so they are beautiful and funny all year round. The "Flower Clock" in Falls, USA, has a clock face consisting of 24,000 flowers, with a diameter exceeding 10 meter, a second hand exceeding 5 meters long, and an hour hand and a minute hand weighing more than 200 kilograms.
