Originated in Mexico at an altitude of 1 500m, it grows well in Gansu, China. It is cultivated by China's largest Dahlia production base-Gansu Dahlia Base, which is deeply loved by people and won many awards in international flower exhibitions.
Gansu Dahlia refers to all Dahlia in Gansu Province, including Lanzhou, Lintao, Linxia, Longxi, Tianshui, Gangu and other places in this province. Gansu Dahlia introduced excellent foreign strains for domestication and hybridization. Because the base is at an altitude of1970m, with little rainfall, abundant sunshine and cool climate, the cultivated dahlias are not only short, but also large and colorful. Moreover, there is no' hidden flowers in leaves' phenomenon, and the overall viewing effect is spectacular. At present, there are more than 300 ornamental dahlias in Gansu, which are especially suitable for planting in barren land and slightly saline-alkali land.
Gansu Dahlia is famous for its large flowers, bright colors, short plants and long flowering period. Especially during festivals, Dahlia is an indispensable combination of bright spots, and it has become a beautiful flower placed in urban streets, parks, institutions, schools, factories and mines. It has also become the new favorite and protagonist of urban flower shows. Because dahlia has a long flowering period and low cost, it has gradually become a new popular trend to hold flower shows.
The planting time of Dahlia is affected by temperature, because it is a plant that is afraid of both cold and heat, so to meet its growth requirements, the surrounding temperature must be stable above 10 degrees. In this way, dahlias can be cultivated in different areas in China, usually in the first half of early spring and March. However, the environmental temperature is different in different regions, and the specific planting time is also different.
Dahlia is very afraid of stagnant water. Don't water too often after planting, especially in rainy weather, and you can also change it to appropriate water spraying according to the situation. It grows in a weak light environment, and its absorption capacity is very low. Don't put it in a light-deficient environment after planting.
