What season does camellia bloom?
As the most dazzling ornamental flower in winter, camellia has become a new favorite in urban gardens with its frost-resistant blooming characteristics. Its unique flowering pattern and profound cultural heritage have achieved a perfect integration of natural gifts and human emotions.
Camellia flowering season pattern
Difference between north and south regions
The 30th parallel north acts as a natural dividing line, with flower buds unfolding in the south in October, while the north has to wait until the ice and snow start to melt in December. The flowering period of Qingdao and Kunming differs by 45 days, confirming the key impact of temperature on flower bud differentiation.
Variety affects the flowering period
The early-flowering variety 'Lieshuang' can bloom in November, while the late-flowering variety 'Shibashan Xueshi' can continue to bloom until the following April. The cold-resistant variety 'Han Chong' cultivated in Japan can maintain its floral posture in -10°C environments.
Camellia winter maintenance skills
Temperature control
The use of double-layer film covering can raise the night temperature by 3-5°C, combined with bamboo windbreaks to form a microclimate. The soil thickness around the base of the ground-planted plant needs to reach 20cm.
Light requirement
Ensure 4 hours of direct sunlight per day around the winter solstice, and use the rotating pot method to ensure even light exposure. The south-facing balcony is the most suitable placement, and glass curtain walls need to prevent excessive UV filtering.
Scientific fertilization method
Apply phosphorus and potassium solution (0.2% concentration) every week during the flower bud expansion period, combined with buried application of decomposed bone meal. Intelligent slow-release fertilizer can maintain a 3-month nutrient supply.
Camellia and urban culture
Ten cities' tour of city flowers
Chongqing named it the 'City Tree and Flower Double Champion', and Wuhan Donghu cultivated a camellia king with a diameter of 18cm. The century-old ancient camellia trees in Qingdao's Badaguan have become a city landmark.
Economic value and cultural connotation
Jinhua cultivated camellia flowers that yield 50kg of tea oil per mu, and Dali Bai people's扎染 craft created a unique tea flower pattern. Traditional Chinese medicine records show that its petals can extract coagulation active ingredients.
From courtyard观赏 to city symbol, camellia decorates the cold winter with a flowering period of half a year. It carries not only the plant characteristics but also a cultural bond that transcends regions, continuing the dialogue between nature and humanities in modern cities.
