What flowers are suitable for growing in Chaohu
Chaohu is located in the middle and lower reaches of the Yangtze River plain, with a unique geographical location that creates a complex ecosystem of low mountains, hills, and water bodies. The distinct subtropical monsoon climate with four distinct seasons, and an average annual precipitation of about 1200 millimeters, provides an ideal growing environment for a variety of flowering plants. Whether for courtyard planting or urban greening, choosing the right species can help plants thrive.
Analysis of Flower Types Suitable for Chaohu
Preferred Perennial Herbs
Herbaceous flowers like Viola yedoensis and Dianthus chinensis, which are tolerant to both moisture and drought, can adapt to the seasonal precipitation changes in Chaohu. Sunflowers and Zinnias, which are heat-loving, can be planted in summer, and their blooming period can last until late autumn. For winter, Viola tricolor and Ornamental kale are recommended, adding color to the city.
Shrub and Tree Planting Suggestions
Deciduous shrubs like Hibiscus syriacus and Crape myrtle have strong germination in spring, and when combined with evergreens like Osmanthus fragrans and Camellia, they can create a landscape that changes with the seasons. Cherry blossoms and Magnolia denudata perform well in Chaohu, with their flowering period from March to April creating a pink sea of flowers. Aquatic areas can be planted with species like Weeping willow and Taxodium distichum that are fond of water.
Detailed Planting Guide for City Flower and Tree
Ecological Characteristics of the Dual City Flowers
Peonies require well-drained, slightly alkaline soil, and have the highest survival rate when divided in autumn. Osmanthus fragrans prefers warm and humid conditions, and during the peak blooming period from September to October in Chaohu, the Jin Gui variety can produce up to 8000 flowers per square meter. Planting both can provide flowers in both spring and autumn.
Key Maintenance Points for the City Tree Paulownia
As the city tree of Chaohu, Paulownia has an upright tree shape of 15-20 meters, and its palmate leaves provide significant shade in summer.

Plant Cultivation Suggestions for Landscape
Soil Improvement Scheme
For the heavy clay soil in some areas of Chaohu, adding 30% humus soil can improve aeration. For potting media, a ratio of peat soil to perlite of 7:3 is recommended to ensure good drainage. The soil pH should be tested before planting, and lime can be spread on acidic soil for adjustment.
Water Management Techniques
In the rainy season, it is necessary to dig drainage ditches to prevent root rot in shallow-rooted plants like Azaleas and Camellias. During high temperatures in summer, watering should be done in the morning and evening to avoid scorching caused by transpiration at noon. For succulent plants, a simple rain shelter can be set up to control the water content of the substrate at around 40%.
The rich geomorphic features of Chaohu provide the possibility for a diverse plant configuration. Mastering key techniques such as dividing peonies and pruning osmanthus, combined with topographical design of plants with varying heights, can not only showcase the unique charm of the city flowers and trees but also build a stable ecosystem. Choosing suitable species and scientific maintenance can keep the garden landscape enjoyable throughout the four seasons.
