What flowers are suitable for Lanzhou
In the warm and humid land of Lanzhou, a pearl in the south of Sichuan, the growth of plants is closely intertwined with urban culture. The unique climate nurtures a variety of flower landscapes, and the city flower and city tree have become the spiritual totems of the city. This article will guide you through the exploration of plant varieties suitable for cultivation in Lanzhou and decipher the ecological code behind the green business card of the city.
Subtropical climate and flower growth characteristics
Three-dimensional climate creates ecological advantages
The average annual temperature in Lanzhou is stable between 17.5-18°C, with a frost-free period of 300 days forming a natural greenhouse effect. The concentrated rainfall from May to September, combined with sufficient sunshine, provides an ideal temperature and humidity environment for most flowers. The unique vertical climate zone in the southern mountainous area has created a stepped planting space from tropical to temperate.
Preferred list of courtyard flowers
Four-season evergreen ornamental plants
Broad-leaf plants like Ficus lyrata and Monstera deliciosa maintain their greenery throughout the year, paired with the red fruits of Cinnamomum camphora, which have a viewing period of half a year. Taxus, as a rare tree species, has both ornamental value and can purify the air.
Seasonal flowering paradigm
In spring, there are kapok and camellias competing for beauty, in summer, lotus and jasmines give off fragrance, in autumn, chrysanthemums accompany osmanthus flowers, and in winter, plum and camellia flowers stand proudly in the frost. Bulbous plants like dahlias and butterflies can achieve annual viewing through flowering regulation.
Interpretation of urban cultural plants
Cassia flower - the city flower that fills the city with fragrance
The city flower, cassia, established in 1986, is widely planted in Lanzhou streets and courtyards. The three main strains of golden cassia, red cassia, and four-season cassia have overlapping flowering periods, and the whole city is immersed in a rich fragrance around Mid-Autumn Festival, with its 'ten miles of fragrance' characteristic becoming the urban olfactory logo.
Longan tree - a win-win model of ecological economy
As the city tree, the longan tree has yellow flowers in clusters in spring and fruits in clusters at the end of summer. The characteristic of still being productive after a hundred years proves the Lanzhou people's urban spirit of 'pragmatism and progressiveness'. Its avenue of trees also serves as a natural sunshade corridor.
From family gardening to urban greening, the people of Lanzhou write ecological wisdom with plants. Choosing suitable varieties and combining scientific maintenance, whether it is courtyard landscape creation or balcony potted plant arrangement, can make this greenery thrive. When the cassia fragrance fills the city, it is the most beautiful footnote of the harmonious coexistence of Lanzhou people and nature.
