Will sweet potatoes bloom? Do all varieties of sweet potatoes bloom?

Because of the great power of communication between people now, people in areas where sweet potatoes are not allowed to bloom can not only see sweet potatoes blooming in other places, but also occasionally appear in places where there were no flowers because of the changes in planting varieties and climate. So sweet potato flower is a strange problem for people in sweet potato flowering areas. Some people think that the place where sweet potatoes can't bloom is not good. Why is this happening? People here have never seen sweet potatoes blossom. Therefore, the two plants that can't blossom in the world are bamboo and sweet potato, and flowering indicates ominous, so there is a strange saying that "sweet potato blooms and husband and wife separate".

I remember seeing an article written by a fifth-grade student in my son's composition sample. I heard that grandpa planted a sweet potato. One day, my grandfather and I went to the field to watch the growth of sweet potatoes. Seeing that the sweet potato is still not big, I asked my grandfather when it will bloom. And that grandpa said that sweet potatoes will bloom. Sweet potatoes only grow vines and leaves, and never bloom. Judging from the situation described by this pupil, I have never seen sweet potato blossom in my life, so I think sweet potato is a non-flowering crop. But in fact sweet potato is a natural flowering crop. Generally speaking, in China, the flowering habits of sweet potatoes in different regions are obviously different. Sweet potato can bloom naturally in autumn and winter in many places in the south, but it usually can't bloom naturally in parts of central and northern China. In this area, if sweet potato wants to blossom, it must be grafted and treated for a short period of time or change its variety characteristics.

There are differences in flowering between north and south sweet potatoes. Sweet potato is a short-day plant, which needs sunshine time and temperature to bloom. After transplanting sweet potatoes, the average sunshine time should not exceed 12 hours, and the night temperature must be below 15 degrees Celsius. When the temperature is kept between 20 degrees Celsius and 30 degrees Celsius during the day, flowers will bloom. On the contrary, it is difficult to see sweet potatoes blossom. In the south of China, south of latitude 23, the growth cycle of sweet potato is long, and the climate is suitable for sweet potato flowering. Therefore, sweet potato flowering is a very common natural phenomenon in southern China. In North China, north of latitude 23, the temperature difference is large and the sunshine time is long, which is not conducive to the flowering and fruiting of sweet potatoes, but it is very beneficial to the expansion of underground nutritious tubers. Therefore, the phenomenon of sweet potato flowering in the north is rare.

There are few flowering phenomena in the north, but the flowering of sweet potatoes is mainly due to the change of climatic conditions. When the weather is high, there is more rain and less light, sweet potatoes will bloom.
