sunflower life cycle

The life cycle of the sunflower is short, approximately six months, and begins with the sowing of the seeds at the end of the cold season, since it is a plant that grows during the warm season.

seed sowing

Sunflower seeds are characterized by being covered by a black layer with a cream-colored line. This layer protects the seed until the temperatures and climatic conditions are favorable for its germination.

When said layer is opened, the germination process begins, which is usually during the spring, in this way the plant feeds better on sunlight.


Sunflower seed germination can take between five and ten days. The seed coat opens, thanks to the moisture in the soil, and the roots begin to sprout. The first root that sprouts is the one that is anchored deeply and strongly, to later support the plant.

The first stem that grows and sticks out of the ground is called a seedling.

plant growth

Sunflower plants have roots that can reach a meter and a half in order to support the large stems of this plant, which can be up to three meters tall. In this way the plant is strongly attached to the soil and absorbs the water and nutrients necessary for its growth and continuous development.

As the stem grows, so will the leaves, which are characterized by having a shape similar to a shovel, and after approximately 30 days, the flower bud is formed, which, even without opening, will turn in the direction of the rays of the Sun to receive its light.

It should be remembered that sunflowers are plants that depend a lot on sunlight to grow and develop, as well as on an average temperature of 25 °C.


The sunflower blooms after a month of plant growth, during which time the flower bud forms and then slowly opens. Once the flower bud is open, the yellow petals become visible, the tips of which curl up at the edges backwards.

After a week, the first petals fall to the ground and are replaced by others of the same colour.


Once the growth process is complete, the sunflower completely drops its petals and the wilting process begins. In this, the flower bud shrinks and from its central points the seeds are formed in the next 30 days.

These seeds will fall to the ground, from some new sunflower plants will be born and others will be consumed.

New outbreak

New sunflower plants will grow from the seeds that fall to the ground, especially if they have the necessary environmental conditions.

sunflower seeds

Sunflower seeds, also called sunflower seeds, are a food rich in minerals such as phosphorus, potassium, magnesium and calcium, which provide health benefits. They are usually consumed after being lightly roasted and, in some cases, with a touch of salt.

Various products can be obtained from the sunflower seed thanks to its high percentage of oil. For example, sunflower oil for cooking, livestock feed and being part of the ingredients of some cosmetics and detergents.
