What kind of flower is this and how to grow it? I'll water it in a few days, thank you.

This is Dragon Boat Flower.

Other names: Maizimu, Shandan.

Habits: Likes a warm, humid and sunny environment. Not tolerant to cold, semi-shade, moisture and strong light.

Cultivation points:

1. Dragon boat flower needs sufficient sunlight, especially during the stem and leaf growth period. Under sufficient sunlight, the leaves will be green and shiny.

2. When the weather is dry, pay attention to spraying water to moisturize.

3. Use 10-20cm pots for potted plants. The potting soil is a mixture of culture soil, peat soil and coarse sand. The seedlings need to be pinched when they are 25 cm tall to encourage more side branches to germinate.

4. Fertilize once every half month during the growth period or use Huiyou 21-7-7 acid fertilizer. If the leaves are found to be yellowing, apply alum fertilizer and water.

5. When potting indoors in winter, the temperature must be kept above 15°C so that the stems and leaves can continue to grow. If the temperature is too low, it will cause defoliation.

Old potted plants need to be repotted after winter and trimmed and reshaped
