Shenzhen recommends the city flower Bougainvillea and the city tree for cultivation and care.

What flowers are suitable for Shenzhen

Under the nourishment of the subtropical climate, Shenzhen, this coastal city, has formed a unique plant ecosystem. The warm environment with an average annual temperature of 22.4°C and abundant rainfall provides ideal growing conditions for more than 300 species of ornamental flowers. We will start by analyzing the climate characteristics to recommend suitable cultivation varieties for different scenarios.

Golden Zone for Subtropical Flower Growth

Optimal Temperature and Humidity Environment

With 2120 hours of annual sunshine duration combined with 70-80% air humidity, it is particularly suitable for the growth of shade-loving plants such as rhododendrons and phalaenopsis orchids. Data shows that the average flowering period of crape myrtle in Shenzhen can reach 180 days, 40% longer than in northern regions.

Key Points for Maintenance During the Rainy Season

Attention is needed during the concentrated rainy season from April to September: for garden plants such as schefflera and pygmy date palm, it is necessary to maintain a soil permeable layer of more than 5cm, and for potted cycads, it is recommended to use ceramsite as a base. In 2023, the municipal botanical garden monitoring showed that scientific drainage can increase plant survival rate by 32%.

Guide to Cultivating Special Plants

Best Green Plants for Balconies

Combining African begonia with autumn begonia can create a year-round flowering landscape. For south-facing balconies, it is recommended to combine bougainvillea with Chinese rocket, which requires 4 hours of direct sunlight per day for growth.

Landscape Combination for Gardens

The color gradient scheme of Ixora and醉蝶花 (ower name not translated) has been popular in recent years, with the peak flowering period from June to August lasting 70 days. Statistics from the municipal greening department show that using Chinese scholars in vertical greening on building walls can reduce the surface temperature by 5-8°C.

Handling Special Varieties

For bulb plants like hyacinths that require vernalization, they can be stored at 4°C in the refrigerator for 30 days for artificial intervention. In the 2022 citizens' planting competition, this method had a success rate of 91%.

Interpretation of the City's Ecological名片

Characteristics of the City Flower, Bougainvillea

The city flower, chosen in 1986, has over 200 ancient trunks remaining, with the hundred-year-old trunks in the Overseas Chinese Town Ecological Square producing up to 20,000 flowers per year. Its salt and alkali resistance makes the survival rate of coastal planting reach 95%.

Ecological Value of the Double City Trees

The mangrove wetland ecosystem supports 98% of migratory birds, with 17 species of true mangroves existing in the Futian Reserve. There are 46 ancient lychee trees over 300 years old, maintaining an annual output of 150,000 jin.

Through scientific selection of varieties and reasonable maintenance, creating a four-season flower landscape in Shenzhen has become a reality. Municipal greening data shows that in 2023, the city's flower coverage increased by 18% year-on-year, and the participation rate of family gardening increased by 27%.
