What flowers are suitable for planting in Lixia
The unique climate of the northwest plateau has given birth to the distinctive plant community of Lixia, a city with the characteristics of both the Loess Plateau and the Qinghai-Xizang Plateau, which has unique advantages in flower cultivation. Abundant sunlight and significant day-night temperature differences provide an ideal growing environment for a variety of ornamental plants.
Plateau Climate and Plant Adaptability
Characteristics of Temperate Continental Climate
Located at 35 degrees north latitude, Lixia has an average annual temperature of 6.3 degrees Celsius and an annual precipitation of 515 millimeters, concentrated in July to September. The typical plateau climate creates a frost-free period of 138 days, with the extreme minimum temperature in winter reaching -27 degrees Celsius. This climate characteristic selects cold and drought-resistant plant varieties.
Recommended Flower Varieties for Survival
Cold-Resistant Ornamental Plants
Hetao牡丹, Ziban牡丹 and other native varieties have strong cold resistance, and their fleshy roots can store sufficient nutrients. Shrub flowers such as lilac and forsythia can bloom as early as March, and Rosaceae plants such as Jinluumei and Zhenzhumei can still maintain good growth in poor soil.
Courtyard Landscaping Combination
Using the three-dimensional configuration of trees, shrubs and herbs: the upper layer is selected with deciduous trees such as栾树 and torchwood, the middle layer is matched with榆叶梅 and posting crabapple, and the bottom layer is planted with Viola yedoensis and Dianthus chinensis to form a ground cover layer. The succulent plant area can be combined with Sedum and Sempervivum species.
City Flower Culture and Development Status
Hetao牡丹 Heritage
The Hetao牡丹, which has been planted since the Jin Dynasty, has 180 traditional varieties. Among them, famous varieties such as 'Zuiyangfei' and 'Qinglong卧墨池' can reach a petal diameter of 20 centimeters, and a complete peony industry chain has been formed, with an annual cultivation of 500,000 seedlings.
City Tree Candidate Varieties
Although the city tree has not yet been officially determined, local species such as Sophora, Populus, and Pinus have received the highest呼声. The characteristics of these species, which are drought-resistant and wind-resistant, highly match the goal of building Lixia into an ecological garden city.
By scientifically selecting suitable varieties, Lixia is building a city landscape system of 'flowers in three seasons and green in four seasons'. In the future, with the cultivation and promotion of new cold-resistant flower varieties, this ancient silk road city will burst into a more beautiful ecological picture.
