When Does Osmanthus Flower
This article provides an introduction to when osmanthus flowers and the blooming period of osmanthus, offering detailed information on the topic.
"Osmanthus Blooms All Over in August" is a popular folk song that also reflects the actual blooming time of osmanthus in most parts of our country. The only thing to note is that "August" here refers to the lunar August, which corresponds to the time around the traditional Chinese Mid-Autumn Festival, that is, from late September to mid-October in the solar calendar. Osmanthus is no exception and blooms mainly during this period. Meanwhile, different regions and annual climatic differences can also affect the blooming time of osmanthus.
The Normal Blooming Time of Osmanthus
There are many varieties of osmanthus, which can be generally divided into golden osmanthus, silver osmanthus, red osmanthus, and evergreen osmanthus. Among them, the evergreen osmanthus can bloom multiple times in suitable places, such as in the warm and humid southern Anhui region, where one can even smell its fragrance in winter. Among golden, silver, and red osmanthus, silver osmanthus blooms the earliest, generally starting to bloom in mid-September, while golden and red osmanthus bloom a bit later, usually from late September to mid-October. This coincides with the traditional Chinese Mid-Autumn Festival, so in addition to eating mooncakes, people can also enjoy the beauty of osmanthus. This has become a traditional activity for Chinese people to celebrate the festival.
Difference inBlooming Time Due to Regional Variations
Different regions have明显ly different blooming times for osmanthus. "August frozen osmanthus" is a common saying among rural elders, meaning that there are always a few days of low temperatures in August, which objectively reflects the general pattern of autumn weather changes and the physiological characteristics of osmanthus blooming. The guiding significance is to clarify that there will be low-temperature weather in August every year and to explain that osmanthus requires low-temperature climate stimulation to bloom.
The climatic feature of China is that the south is higher than the north, and low-temperature weather arrives from north to south. Therefore, low-temperature weather comes earlier in the north, stimulating the osmanthus to bloom earlier. So, in suitable planting areas in the north, osmanthus will bloom a few days earlier. According to recorded observation, the same variety of osmanthus planted in Jinan, Shandong, and Hangzhou, Zhejiang, will bloom 8 days earlier in Jinan than in Hangzhou.

Annual Climate Differences Also Affect the Blooming Time of Osmanthus
Due to the sensitivity of osmanthus blooming to low temperatures, annual climate changes can also affect the blooming time of osmanthus. For example, in 2019, most parts of our country experienced persistent drought and warm autumn weather, with low temperatures arriving late. By the time of the annual blooming period of osmanthus in late September, there was still no sign of osmanthus flowers. Even as the Mid-Autumn Festival approached, many osmanthus trees only managed to bloom a few sparse flowers, leaving those who looked forward to enjoying osmanthus flowers during the festival with great regret. However, this year the climate is normal, with abundant rainfall, and the golden osmanthus is already in full bloom by mid-September.
Therefore, if the autumn temperature is high and low temperatures are late to arrive, it will affect the timely blooming of osmanthus. In warm autumn years, the blooming time of osmanthus will be postponed until the arrival of low temperatures, which will stimulate the blooming of osmanthus and give osmanthus lovers a surprise of "suddenly one night the cold wind blows, and the osmanthus trees are covered in flowers."
Conclusion
Golden osmanthus is one of the many osmanthus varieties in our country. It blooms slightly later than silver osmanthus and synchronously with red osmanthus, generally blooming from mid-September to mid-October. The geographical location affects the blooming time of local golden osmanthus, with northern regions generally seeing osmanthus bloom 7-8 days earlier than in southern regions. At the same time, annual climate differences can also influence the blooming time of osmanthus. Generally, warm autumn weather will delay the blooming of golden osmanthus until obvious low temperatures appear, at which point the osmanthus will "shiver" and bloom beautifully.
