Sunflower has a well-developed root system, including main roots, lateral roots and fibrous roots. The stems are upright and have a rough surface. There are two types of leaves: cotyledons and true leaves, with the true leaves being more numerous. The flowers grow on the flower disk and are mostly yellow in color. The fruit is commonly known as melon seeds and is edible. In daily maintenance, sufficient light is needed and the temperature should be kept above 10°C. Water more during the flower bud stage, and do not require much water at other times.

1. Morphological characteristics

1. Roots: Roots are divided into main roots, lateral roots and fibrous roots. The main root is relatively deep and grows vertically into the ground. There will also be lateral roots growing on it, growing horizontally. Fiber roots will also grow on the lateral roots.

2. Stem: The stem is upright, with a rough surface and bristles. In the later stage, it will become lignified and hollow inside. The color of the embryonic stem in the seedling stage can distinguish its variety.

3. Leaves: Leaves are divided into cotyledons and true leaves. There is only one pair of cotyledons and more true leaves, which are opposite or alternate and have bristles on the surface.

4. Flowers: There is a flower disk at the top of the sunflower stem, and there are two kinds of flowers on the flower disk. There are ligulate flowers growing in a circle around the periphery of the flower disk, and tubular flowers growing inside the flower disk. The color is mostly yellow.

5. Fruit: The seeds are long, with a shell with black and white stripes on the outside, and the cotyledons inside are edible, commonly known as melon seeds.

2. Maintenance methods

1 Temperature: Sunflowers do not have high temperature requirements and can grow healthily as long as it is above 10°C.

2. Water: Sunflowers have little demand for water during their growth period. But when the flower bud stage begins, more watering is needed. Less water will reduce the number of seeds.

3. Light: Sunflowers, commonly known as sunflowers, are naturally inseparable from light at all stages of growth. Sufficient light can ensure its strong growth, vigorous stems and leaves, and plump seeds.
