How to distinguish Jingui, Yin Gui, Dangui and Sijigui when there are no flowers?
Osmanthus fragrans variety group: it blooms all year round, and there are varieties such as "laurel", "Osmanthus fragrans" and "Osmanthus fragrans".
Yin Gui variety group: it blooms in autumn, and it is pure white, milky white and yellowish white. There are varieties such as Seed Yin Gui, Jiulong Guigui, Early Yin Gui, Late Yin Gui and Bai Jie.
Jingui Variety Group: It blooms in autumn with lemon yellow to golden yellow flowers, including Dahua Jingui, Dayehuang, Huangchuan Jingui, Late Jingui and Round-leaf Jingui.
Osmanthus fragrans variety group: It blooms in autumn, and its color is dark, orange yellow, orange red to vermilion. There are varieties such as "Dahuadangui", "Yadangui", "Zhusha Dangui" and "Broad Leaf Red". There are some varieties worthy of popularization and application in each variety group, such as Osmanthus fragrans and Phyllostachys macrophylla, which are small shrubs with a height of 0.5-1.5m. "Osmanthus fragrans" has a light yellow flower, and each node of the same branch blooms one after another, and flowers appear almost every day, hence the name. There are a large number of mother plants in Cangxi, Sichuan. "Big-leaf Buddha's Dingzhu" has milky white to pure white flowers, dense inflorescences and unique terminal inflorescences, which bloom continuously from spring to autumn. They have high ornamental value and can be potted indoors or planted outdoors in a large area.
Different species or varieties can be selected for breeding according to different needs. For the purpose of picking flowers, high-yield types with dense flowers should be selected, such as "Huangchuan Jingui", "Jingui", "Seed Yin Gui", "Big Flower Dangui" and "Orange Red Dangui". For the purpose of seeing flowers and smelling fragrance, osmanthus fragrans, Osmanthus fragrans, Osmanthus cinnabarinus, Osmanthus fragrans and Osmanthus fragrans should be selected. Shrubbery, potted plants and bonsai should be selected from "Fusang", "Big Leaf Buddha's Fixed Pearl", "laurel", "Four Seasons Cinnamomum", "Kowloon Cinnamomum" and "Willow Cinnamomum". And take them as trees or choose "Huang Yingui with big leaves", "Jingui", "Dangui with big leaves" and "Jingui with big Dan" as the garden owners of Jing Yi.
Some sweet-scented osmanthus bears fruit, while others bear no fruit. Drupe usually ripens in April-May of the following year, and it usually takes 5-6 years to blossom when sowing. Cutting branches, grafting and layering used for asexual reproduction can bloom in the same year.
The Song Dynasty recorded: "When the moon is full of flowers, the flowers will be damaged, and the moon will be lost. It is important to know that everything in the world is in the clear autumn ",which points out the basic law of its flowering: that is, when the lunar calendar is full in August and May every year, osmanthus will bloom, and after half a month, the flowers will wither and the moon will be lacking.
Osmanthus fragrans likes warmth, has strong resistance to stress, is both resistant to high temperature and cold, and can overwinter in the open air in the south of Huaihe River in Qinling Mountains in China.
Osmanthus fragrans likes sunshine, but also can resist shade. In full light, it has lush foliage and dense flowers. In the shade, its branches and leaves are sparse and flowers are scarce. If potted indoors in the north, it is especially necessary to pay attention to sufficient light to facilitate growth and flower bud formation.
The ancients recorded a lot about the weather conditions of osmanthus flowers. Looking at the Moon at Fifteen Nights by Wang Jian in the Tang Dynasty includes "Coody Leng's Silent Wet Osmanthus fragrans", Liu Zongyuan's "Exposing Osmanthus fragrans in front of the mountain", Bai Juyi's "Steaming autumn air in the sky, golden waves picking yellow flowers in the middle of the month", and Lu You in the Song Dynasty's "Exposing wet fragrance in the secluded path, drying small windows in the setting sun". "Coody Leng" and "Mi Lu" in the poem mean that it will be cold in the morning and evening; "steaming" means that the weather will have a higher temperature again. This cold weather in the morning and evening and sultry weather in the daytime is not only beneficial to the nutrient accumulation of osmanthus trees, but also can promote the formation of rain dew and accelerate the flowering of osmanthus trees. Suzhou people call it "turpentine steaming". Around the Mid-Autumn Festival, the weather suddenly gets hot, just like summer. Once the osmanthus is steamed, it will rot and bloom for a long time. Osmanthus fragrans flowers need both a certain humidity and a certain temperature difference.
Osmanthus fragrans is not strict with the soil. Except alkaline soil and low-lying land or soil that is too sticky and poorly drained, it can generally grow, but slightly acidic sandy loam with deep soil layer, loose and fertile soil and good drainage is the most suitable.
Osmanthus fragrans is resistant to chlorine, sulfur dioxide, hydrogen fluoride and other harmful gases, and has strong dust adsorption ability, which is often used for greening in cities and industrial and mining areas.
People like osmanthus. At present, 16 provinces (autonomous regions), cities and counties in China regard osmanthus fragrans as the city flower, provincial flower and county flower. Five old osmanthus producing areas in history: Xianning in Hubei, Wuxian in Suzhou, Guilin in Guangxi, Manjuelong in Hangzhou and Xindu in Sichuan.
Osmanthus fragrans is a symbol of nobility, chastity, honor, friendship and good luck. Those who succeed in official career are called "laurels". The myth of "Moon Palace Fairy" has given the world endless reverie. In the long historical development process, Osmanthus fragrans has formed profound cultural connotations and distinctive national characteristics.
