Cultivation techniques:

The quality of cultivated soil is better than loam or sandy loam, and the drainage is good. Sex is fond of high temperature, and the suitable temperature for childbearing is about 2332 degrees C. Winter needs to be warm and sheltered from the wind. Adapt to the environment from half-day to full-day sunshine, the scorching sun will make the leaves yellow, but does not affect the growth and flowering. In winter, the low temperature and cold current will have the dormancy phenomenon of deciduous leaves. Flowers bloom in spring and summer, inflorescences protrude from the branches, and blossoms bloom for a long time. Dwarf pruning can be carried out after flowering to avoid getting taller and thinner. Apply a long-acting fertilizer at the end of winter and the beginning of spring, and replenish it again after flowering.

The origin of the name:

When the blue butterfly is in full bloom, it is very similar to a group of butterflies, and the flower is graceful. It is named Blue Butterfly because it looks like a butterfly. Blue butterflies have purple flowers as beautiful as butterflies, which bloom only once in a thousand years, and only in the forest with no return! No return to the forest, as the name implies, there is no return, which is extremely dangerous, therefore, few people can see purple butterfly!
