What flowers are suitable for raising in Xigaze
In the sunlit city at an altitude of 3,800 meters, the cultivation of flowers is both challenging and unique. The special highland climate of Xigaze nurtures a distinctive plant ecosystem, and mastering the matching rules of climate and plant characteristics is the key to creating a highland garden.
Highland Climate and Plant Adaptability Features
Day and Night Temperature Difference and UV Protection
The average temperature difference of 12°C requires plants to have good stress resistance, and it is recommended to choose varieties with thicker leaf cuticle layers. The UV index is consistently above level two, and native plants such as purple spot gentian and alpine azalea have inherent radiation resistance genes.
Water Management in Dry and Wet Seasons
90% of the annual precipitation is concentrated from May to September, and it is necessary to use sandy soil with strong drainage for cultivation. In winter, the air humidity is less than 30%, and xerophytic plants like the狼毒花 (Euphorbia fischeriana) can store water independently through their succulent roots.
Guidelines for Planting Flowers with Highland Characteristics
Recommended Ground Planting Varieties
Gesang flower (eight-petal plum) has outstanding cold and drought resistance, and grows vigorously in the temperature range of 5-20°C. Combined with the flower borders of Taguang and Tibetan polygonum, a layered three-dimensional landscape can be formed.
Potted Plant Maintenance Plan
It is recommended to plant epiphytic orchids such as tiger head orchid indoors, using bark substrates to maintain breathability. Windowsills can display a combination of longevity flowers and succulents, requiring two scattered light exposures per week to maintain growth.
Prospects for Cultivating the Symbolic Plants of the City
Although the city flower and city tree have not yet been officially established, the alpine azalea, which can bloom at altitudes above 4,500 meters, has become a popular candidate. Unique species such as Tibetan cedar also have the potential to become city trees.
By scientifically selecting suitable species and combining them with stepped planting designs, it is possible to create an ecological courtyard with flowers blooming all year round, even in highland areas. It is recommended to prioritize the introduction of domesticated local species and gradually establish a stable courtyard ecosystem.
