Osmanthus fragrans blooms from August to September, and chrysanthemum 10- 1 10.
Osmanthus fragrans is the common name of many trees of Oleaceae in China. It is a representative species of Oleaceae, also known as osmanthus fragrans. It is an evergreen shrub or small tree with hard skin, long oval and sharp leaves, which are opposite and will not wither in winter.

There are many varieties of horticulture, among which Jingui, Yin Gui, Dangui and laurel are the most representative.
Chrysanthemum is a perennial herb of Compositae and Chrysanthemum in plant taxonomy.

According to the appearance of petals, it can be divided into garden hug, retreat hug, reverse hug, disorderly hug, happy hug, flying hug and other cultivation types. Different types of chrysanthemums are named after different varieties.
Extended data:
After long-term planting, natural hybridization and artificial breeding, osmanthus fragrans has produced many cultivated varieties. Through further investigation and arrangement, 32 osmanthus fragrans varieties were preliminarily identified. As far as color is concerned, there are Jingui, Yin Gui and Dangui. From the leaf type, there are willow leaf laurel, golden leaf laurel, dripping yellow, sunflower leaf and firewood handle yellow; As far as the flowering period is concerned, there are eight laurels, four seasons of laurel and beautiful months. ?
Osmanthus fragrans has formed many cultivated varieties through long-term artificial cultivation, natural hybridization and artificial selection. In this paper, the resources and varieties of osmanthus fragrans in major cities in China were extensively investigated, and the flowering characteristics of osmanthus fragrans were recorded on the spot. The characters of different types of osmanthus fragrans were analyzed and compared, and relatively stable genetic characters were selected. Four sweet-scented osmanthus varieties were identified and sorted out through traditional classification methods and their application in garden production.
Osmanthus fragrans adapts to subtropical climate. Sexual preference is warm and humid. The average temperature in the planting area is 14-28℃, the average temperature in July is 24-28℃, the average temperature in June is above 0℃, the minimum temperature is-13℃, and the optimum growth temperature is 15-28℃. Humidity is very important for the growth and development of osmanthus fragrans. The annual average humidity is 75%-85%, and the annual precipitation is about 1 1,000 mm. Especially when young trees and adults bloom, they need more water. If there is drought, it will affect flowering, and strong sunshine and shade are not good for their growth. Generally they need 6-8 hours of light every day.
