Sweet potatoes will bloom, with axillary cymes with 1-3-7 flowers gathered into an umbrella shape. The peduncle is 2-10.5 cm long, slightly stout, hairless or sometimes sparsely pubescent; the bracts Slices are small, lanceolate, 2-4 mm long, apex awn sharp or abrupt, falling early; pedicels 2-10 mm long.

Flowering habits vary with varieties and growing conditions. Some varieties bloom easily, while others bloom when the climate is dry. Flowering is common in areas with high temperatures and short days, and is common in areas with lower temperatures. Flower less. The capsule is oval or oblate, with false septa divided into 4 chambers. Seeds 1-4, usually 2, hairless.

Extended information:

The shape and color of leaves often vary depending on the species, and sometimes the same plant has different leaf shapes, usually wide oval, 4-13 cm long. , 3-13 cm wide, entire or 3-5 (-7) lobed, lobes broadly ovate, triangular ovate or linear-lanceolate, base of the blade heart-shaped or nearly truncate, apex acuminate, both sides It is sparsely pubescent or nearly hairless, and the leaf colors include dark green, yellow-green, purple-green, etc.

Sweet potatoes like light and are short-day crops. Plants have high requirements for light energy during their growth and are crops that are intolerant to shade. The longer the light energy is from the stem and leaf stage, the longer the growth period and the higher the photosynthetic efficiency. Otherwise, the photosynthetic efficiency will be reduced and the plant growth will be affected. The daily sunshine time should be 8-10 hours. Sufficient light can not only promote flowering and form root masses.

Sweet potato is a nutritious and rich natural nourishing food, rich in protein, fat, polysaccharide, phosphorus, calcium, potassium, carotene, vitamin A, vitamin C, vitamin E, vitamin B1, vitamin B2 and 8 amino acids. According to scientists' analysis, its protein content is 7 times more than that of rice; its carotene content is 3.5 times that of carrots; and its vitamin A content is 100 times that of potatoes.
