What flowers are suitable for cultivation in Qiannan
Located in the Yunnan-Guizhou Plateau, the Qiannan Buyei and Miao Autonomous Prefecture boasts a unique geographical environment and climatic advantages, making it an ideal growth area for numerous ornamental plants. The立体 climate and the alternating, humid monsoon provide a natural nurturing environment for flowers with different habits.

Analysis of the geographical and climatic characteristics of Qiannan
The three-dimensional climate creates a diverse ecosystem
With a mild environment of annual average temperatures ranging from 13.6 to 19.6°C, combined with abundant rainfall of over 1200 millimeters per year, it forms a typical subtropical humid climate with no severe cold in winter and no severe heat in summer. The vertically distributed hilly terrain has formed multiple microclimate zones, allowing for the cultivation of ornamental plants from different temperature zones in the 500-1500 meter altitude range.
Seasonal rainfall distribution characteristics
The concentration of 45% of the annual rainfall from June to August requires flowers to have good drainage and flood resistance. The day-night temperature difference in spring and autumn can reach over 10°C, so attention should be paid to the temperature adaptability of the plants when selecting them.
