What flowers are suitable for Dandong
As an important ecological barrier in the Northeast region, Dandong's unique geographical location has created its warm and rainy monsoon climate. The climatic characteristics of long and cold winters and hot and rainy summers provide ample water for plant growth and also pose special requirements for the cold resistance of courtyard green plants. This article will systematically comb the key points of flower planting in Dandong and interpret the ecological code behind the city flower and tree.
Dandong's climatic characteristics and plant suitability
A climate map with distinct seasons
Abundant annual precipitation of 800-1200 mm, combined with temperature changes from -8°C to 26°C, forms a typical temperate monsoon climate. A spring transition period of 45 days in April, 70% of the annual rainfall concentrated from June to August, the golden planting period of clear and refreshing autumn from September to October, and a low-temperature dormancy period of 5 months from November to the following March constitute a unique planting timeline.
Optimal list of courtyard flowers
For ground planting, it is recommended to choose cold-resistant varieties such as honeysuckle and wintersweet, whose roots can withstand temperatures as low as -25°C; for potted plants, indoor ornamental plants such as hawthorn and green taro can be selected, with heating control for overwintering. The locally acclimatized varieties of Dandong, such as pearl viburnum and wild chrysanthemum, are especially recommended, with a survival rate as high as 92%.
Cultural symbols of city flowers and trees
The ecological code of rhododendron
As the city flower of Dandong, the rhododendron shows amazing adaptability to the environment. Its leathery leaves can resist dry and cold air in winter, and its developed fibrous root system can effectively absorb mountain humus. Every May, the sea of rhododendron flowers in Jinjiang Mountain Park attracts over 300,000 tourists, testifying to its landscape value.
The time imprint of ginkgo trees
There are 237 ancient ginkgo trees in the city, among which the 800-year-old tree in the Jiuliancheng Relics site has a diameter of 2.8 meters. The annual rings of ginkgo trees record the history of Dandong's opening to the world, and the golden road formed by its fan-shaped leaves in autumn has become a city geographical landmark. After the city tree status was established in 1984, the proportion of new roads with ginkgo trees increased to 45%.
On this warm and humid land of Dandong, from courtyard flowers to urban greenery, the perfect integration of nature and humanities is reflected. Choosing suitable varieties and matching seasonal maintenance, whether it is the brilliant rhododendron or the weathered ginkgo, they can all showcase their unique charm in the cycle of the seasons.
