What Flowers are Suitable for Growing in Guang'an
In the eastern part of Sichuan Basin, the humid climate and abundant rainfall nurture a unique urban greenery in Guang'an. In this city favored by clouds and mist, whether it's a small balcony or street corners, one can always encounter stunning floral landscapes that captivate passersby. What kind of plants can perfectly match the gentle temperament of this city? Let's explore the suitable plants for Guang'an based on its climatic characteristics.
The Relationship Between Guang'an's Natural Endowment and Plant Growth
Plant Selection Logic in the Gentle Climate
Situated at 30 degrees north latitude, Guang'an has a stable annual average temperature of around 17°C, combined with more than 1200 hours of annual sunshine, creating a typical environment of low light and high humidity. This climatic feature determines that shade-tolerant and moisture-loving plants are more likely to survive. Data shows that the local air humidity is often above 75%, especially suitable for the growth of orchidaceae, araceae, and other plants.
Key Points for Maintenance in Seasonal Changes
The average temperature of 6°C in January requires choosing cold-resistant varieties in winter. It is recommended to adopt a stepped planting strategy: using evergreen shrubs as the base, combined with perennial herbs to form a three-dimensional landscape with varying heights. Special attention should be paid to shading measures during the high-temperature period in July to prevent strong sunlight from burning the leaves.

Recommended List of Balcony Flowers
Southern-facing balconies can choose bougainvillea combined with jasmine to create a fragrant flower landscape; north-facing spaces are suitable for combining green vines and bamboo. Experimental data shows that using a hanging planting method with吊兰 (吊兰) + peace lily can increase the greenery rate of small spaces by 40%. Key points for maintenance include: keeping the substrate loose, applying diluted liquid fertilizer monthly, and ensuring ventilation and pest control.
Special Plant Culture Interpretation
Osmanthus, as the city flower, has a thousand-year history of cultivation in Guang'an. The osmanthus trees in the Osmanthus Alley in the south of the city, over 200 years old, emit a fragrance that fills the streets for十里 (ten miles) every golden autumn. The camphor tree, as the city tree, has volatile substances that naturally repel insects. The 5-kilometer-long camphor forest avenue along the riverside has become a city hallmark. Both plants embody the beautiful meaning of 'fragrance filling the world.'
Plant Landscape Construction Techniques
In courtyard design, a layout of 'flowers in three seasons' can be adopted: using magnolia in spring, lotus in summer, and chrysanthemum in autumn. Public spaces recommend using crape myrtle arrays, which have a flowering period of up to 100 days and are easy to prune. It is worth noting that the soil in Guang'an is generally acidic, and the pH value needs to be adjusted to around 6.5 before planting.
From balcony potted plants to urban landscapes, Guang'an's greenery is blossoming in different scales. Choosing suitable plants is not only about survival rates but also a process of communicating with the city's temperament. When the fragrance of osmanthus permeates the streets and the green shade of camphor trees protects pedestrians, the plant code of this city has been written into every corner.
