How Does a Sunflower Spread Its Seeds? A Full Breakdown of Dispersal Methods

Sunflowers are very vibrant plants, and we all love them in everyday life. So do you know how sunflowers spread their seeds? Let's take a look!

1. How sunflowers spread their seeds

Sunflowers mainly rely on wind and animals to spread their seeds. After they fall off naturally, the wind carries them far away; when animals feed on them, they also drop some seeds along the way.

2. The difference between moss rose and sunflower

1. The moss rose has a small flower head and flowers in a variety of colors. Besides the common yellow, there are also purple, red, orange and other colors. The whole plant is about thirty cm tall, and its petals take up a larger share of the flower head than the seeds do. The sunflower, by contrast, is only yellow, the plant is one and a half to three m tall, and the seed disc takes up two thirds of the flower head's area. Judging by these outward features, the two are completely different plants.

2. The moss rose's seeds are very small, and some varieties have no seeds at all; its seeds cannot be eaten directly. The sunflower's seeds are the “melon seeds” we often eat. They are much bigger than moss rose seeds and can be eaten directly. The sunflower seed oil on the market is extracted from its seeds.

3. Besides its ornamental value, the moss rose also has medicinal uses. The whole plant of the large-flowered purslane type can be used as medicine; it has the effect of clearing heat and reducing swelling, and can be used to treat burns and bruises. The hairy purslane type can treat knife wounds; people in ancient times crushed it and applied it directly to the wound to stop bleeding. The sunflower's main effects, meanwhile, are lowering blood pressure and blood lipids, strengthening the stomach and promoting urination.
