1. Sowing and propagation

First, collect its seeds. Pay attention to the plump and healthy seeds. The newly picked seeds may contain more water. We can dry them in the shade for 3 to 4 days and then dry them in the sun. It is best to plant seeds after the beginning of autumn and before light snow. Before sowing, soak the seeds in water for about one night. Then plant the soaked seeds into the pot soil prepared in advance, and then pour enough water. After that, keep the soil moist and give it an appropriate temperature. It will germinate in about 40 days

2. Tuber propagation

This breeding method requires us to cut ourselves. The time is usually in late August, because the tubers are about to sprout at this time. We should cut the tuber longitudinally from its top into several small pieces, pay attention to each piece should contain bud eyes, and apply plant ash to the incision for sterilization. Then put it in a cool place to dry, and then you can plant it in a pot prepared in advance. As long as you keep it patiently, it will soon grow leaves

3. Tissue culture propagation

We can select the young stem or stamen of the plant that has grown for 1 to 2 years as the explant. Then use hormone to induce it to grow seedlings, in which the stem block is the most easily induced. If the stem block is selected as the explant, we can use MS medium. After the seedling grows, let it gradually accept the light, and then implant it into the pot soil prepared in advance. Given the appropriate environment, it will soon grow leaves and blossom. But this method is not very practical for families, so we usually choose the first two methods
