What flowers are suitable for planting in Dongying
As a central city of the Yellow River Delta, Dongying's unique geographical location has created distinct seasonal landscapes. The significant temperature difference between winter and summer tests the wisdom of urban greening, while also providing diverse options for home gardening.
Principles of Climate and Plant Adaptation in Dongying
Characteristics of Temperate Monsoon Climate
An average annual temperature of 12.8°C and 550mm of precipitation create a typical climatic cycle of spring drought, summer flooding, autumn coolness, and winter dryness. Especially the extreme low temperature of -10°C in winter requires that ground-planted plants must have cold resistance genes.
Three Key Elements for Courtyard Planting
Selecting plants needs to focus on three core indicators: frost resistance (30cm underground), adaptability to saline-alkali soil (pH 7.5-8.5), and wind resistance (average wind speed of 3.5m/s), to ensure the survival rate of plants.
Preferred List of Courtyard Plants
Star Ground-Planted Varieties
Deep-rooted woody plants like wintersweet and peony can withstand severe cold of -15°C; perennial flowers like daylily and iris can safely overwinter underground; annual herbs recommend drought-resistant cosmos and flood-resistant lythrum planting combinations.
Balcony Potting Solution
Choose shade-tolerant cycas palm combined with sun-loving bougainvillea, with an automatic drip irrigation system, to create a vertical green space. Recommended combination: upper layer hanging ivy + middle layer ornamental leaf calathea + lower layer succulent combination.
Interpretation of Urban Ecological Business Card
Ecological Value of Lotus
The lotus, the city flower, is widely planted in Dongying Wetland Park. Its developed ventilation system can purify water, with a single plant processing up to 50 liters of sewage per day. The blooming period lasts from June to September, creating a unique ecological landscape.
Protective Function of Chinese Scholar Tree
The compound leaves of the Chinese scholar tree can effectively absorb dust, with a single tree annually retaining up to 18kg. Its deep roots can stabilize saline-alkali soil, with wind resistance reaching the standard of level 10, making it an ideal protective forest species.
From home gardening to urban greening, Dongying people write an ecological answer with plant wisdom. Choosing suitable species can not only reduce maintenance costs but also form a clear landscape hierarchy. When the new green of the Chinese scholar tree meets the first bloom of the lotus, this wetland city ushers in the most beautiful ecological season.
