What flowers are suitable for cultivation in Xing'an League
Located in the northeast of Inner Mongolia, Xing'an League's unique geographical location has created a typical temperate continental monsoon climate. The sharp contrast between the severe cold and long winters and the short and warm summers presents special challenges for local flower cultivation. Understanding the climate characteristics and the growth patterns of plants can create a courtyard landscape that is adaptable and has distinct seasons.
Climate characteristics and plant selection basis
Analysis of temperate monsoon climate characteristics
With an average annual temperature of 3.5-5.5°C, Xing'an League has a frost-free period of only 100-120 days a year, and annual precipitation of 380-450mm, concentrated in the summer. The unique climate with day and night temperature differences of 12-15°C requires garden plants to have cold and drought resistance, as well as adaptability to strong sunlight.
Recommended outdoor cultivation varieties
Years of practice have shown that perennial flowers such as Lilium pumilum, hibiscus, and dahlias perform well. Among them, Lilium pumilum can tolerate temperatures as low as -30°C, and its bulbs can safely overwinter in frozen soil; the tubers of dahlias need to be buried 30cm deep and covered with straw to achieve perennial cultivation.
Indoor potted plant combination plan
It is recommended to use a combination of succulent plants and shade-tolerant green plants: cacti ensure winter ornamental value, and broad-leaved plants like epipremnum and吊兰 regulate humidity. It is especially important to maintain an indoor temperature of above 15°C and control watering frequency from October to the following April.
Discussion on candidate varieties for city tree and city flower
Although the official designation has not yet been made, among the common local tree species, Pinus sylvestris var. mongolica, as a representative species for windbreak and sand fixation, has received increasing calls in recent years. In terms of flowers, Lilium pumilum and gold莲花 are popular candidates due to their ornamental value and ecological adaptability.
Courtyard planning is recommended to use stepped planting: the foreground area is arranged with low-growing varieties such as Dianthus and iris, the middle layer is cultivated with shrubs such as hibiscus and forsythia, and the background is selected with trees such as magnolia to form a three-dimensional landscape. Combined with climbing plants like Campsis and Parthenocissus, space can be effectively utilized.
