The distinct day and night temperature difference is especially suitable for cultivating cold and drought-resistant varieties.
Soil Environment Characteristics

Selected Shrubs and Flowers
Roses, as the city flower, have over 200 cultivated varieties, ranging from climbing roses to tree roses. Forsythia blooms golden yellow in early spring, complementing the color scheme of purple syringa. The shade-tolerant pearl bush performs well in the shade of the courtyard.
Herbaceous Plant Combinations
Large-flowered daylilies and hostas form a shade-tolerant combination, while irises and peonies create a waterside landscape.矮牵牛 (Petunias) and Tibetan poppies form a long-lasting flower border. It is recommended to use stepped planting to ensure continuous seasonal viewing.
Cultural Connotations of the City's Symbolic Plants
Cultural Symbolism of Roses
Since being designated as the city flower in 1983, roses account for 18% of Dalian's urban绿化 (greening). Their ability to bloom throughout the seasons echoes the city's positioning as the "City of Romance," with each administrative district featuring its own rose theme park.
Ecological Value of Locust Trees
As the city tree, the Chinese scholar tree accounts for more than 30% of the street trees in the main urban area. During the peak bloom of Chinese scholar trees in July, Xinghai Square to the Seaside Road forms a sea of fragrant snow. Their deep root systems effectively prevent soil erosion, with an annual carbon sequestration capacity of 68 kilograms per tree.
When configuring plants, it is recommended to adopt a strategy of "base with city trees, highlighted with city flowers, and filled with suitable varieties." By reasonably mixing trees, shrubs, and herbs, it can not only highlight the city's characteristics but also build a stable ecological community. Regularly attending horticultural lectures held by the Labor Park can provide the latest cultivation techniques.
