1、 Are there any flowers

Yams have flowers. It is a perennial vine of Dioscorea in dioscoreaceae. Its tubers are oblong and usually grow vertically, with a length of up to 1 meter. The stem is purplish red without hair. The leaves are simple, the lower part is alternate, and the upper part is opposite. Its flowers open from June to September, and its inflorescence is spike shaped. There are 2-8 male inflorescences and only 1-3 female inflorescences

2、 How

1. Soil: yam cultivation generally requires a deeper pot. Its rhizomes grow vertically. Only when the soil layer is deep can it grow longer. In addition, the soil should be loose and fertile with good drainage, so as to avoid the basin soil being too wet and affecting the development of plants. In addition, certain base fertilizer can be mixed into the soil to provide nutrients for its growth

2. Light: yam likes light, but it belongs to short sunshine plants. We must pay attention to controlling the light duration. If the light duration is too long, although the branches and leaves will grow luxuriantly, the rhizome will not grow well, and the flowering period will be delayed. Usually, let it receive strong light every day, but the time should not be too long, which can promote the development of rhizomes

3. Watering: yam has good drought resistance and little demand for water, so it doesn't need too much watering. Watering is usually carried out after the soil is dry, which can avoid too much soil humidity and inhibit root respiration. If you pour too much water, you need to drain the excess water immediately and strengthen the ventilation to let the water evaporate quickly

4. Fertilization: the demand for fertilizer during the growth period of yam is not very high. A little nitrogen fertilizer can be added in the early stage to promote the growth of plant branches and leaves. In order to promote its flower bud differentiation, a little phosphorus and potassium fertilizer can be applied in the medium term. In the later stage, Hefei will be restored to supplement more comprehensive nutrients
