What Flowers are Suitable for Shanghai
In this international metropolis of Shanghai, creating a private garden requires considering the climate factors first. The subtropical monsoon climate brings a cycle of four seasons and a warm environment, creating unique conditions for plant growth. Mastering the two key points of flood prevention during the rainy season and keeping warm during the winter can make the courtyard bloom with different colors throughout the year.
Planting Advantages of Subtropical Climate
The combination of an average annual precipitation of 1200 millimeters and abundant sunshine makes Shanghai a natural greenhouse for plant growth. The characteristics of a 10℃ temperature difference between day and night during spring and autumn are especially suitable for the color accumulation of flowers such as azaleas and camellias. Using a sunshade net during the high-temperature periods of summer can extend the观赏 period of hydrangeas.

Cultural Code of the City's Symbolic Plants
White magnolia was established as the city flower in 1986, and its early spring blooming symbolizes the city's pioneering spirit. In key areas such as People's Square and Xujiahui Park, the magnolia exhibition held in March has become a tradition for the citizens. Although the plane tree has not been officially listed as the city tree, the French plane trees on both sides of Hengshan Road have formed a unique urban memory symbol.
Practical Maintenance Tips
In response to the high humidity environment during the plum rain season, it is recommended to use ceramsite as the base combined with peat soil cultivation medium. When cold waves come in winter, building a simple plastic greenhouse for potted plants can effectively prevent freezing. In terms of pest and disease control, regularly spraying garlic extract can prevent the multiplication of red spiders.
From the classic gardens of Guyi Garden to the modern community balconies, Shanghai's flower-raising culture is gaining new vitality. By reasonably matching trees, shrubs, and herbs, combined with an intelligent irrigation system, even high-rise residential buildings can create a vertical green space. Citizens might as well try to pair white magnolia with camphor trees, which not only highlights the urban characteristics but also forms an ecological microcycle.
