What is a Sunflower?
The sunflower is a flower that is predominantly yellow with a hint of red. Its large head spans 19 – 27cm and is surrounded by numerous petals with a dark center. This flower is native to multiple countries, and its meaning varies across cultures. In neighboring China, the sunflower symbolizes longevity, while in Europe, it represents steadfastness and a forward-looking perspective.
Sunflower Characteristics
Stem: Sunflowers are herbaceous and annual plants with straight and sturdy stems covered in fine hair. They typically grow to a height of 1-3.5 meters.
Leaves: Sunflower leaves are large, pointed at the tip, and heart-shaped at the base. The leaf stalks are long, and both sides of the leaves are covered in fine white hair.
Flowers: Sunflowers have large flower heads with a diameter of 7-20cm. The flowers bloom widely, with evenly arranged, bright yellow petals.
Seeds: Sunflowers take around 3-5 months to bloom fully. After the petals wither, the seeds become visible. Sunflowers are propagated by seeds, and the offspring inherit the same characteristics as the parent plant.
Always Facing the Sun
Perhaps the most well-known characteristic of sunflowers is their tendency to face the sun. In the morning, when the sun rises, sunflowers face east. In the afternoon, as the sun moves towards the west, the flowers turn accordingly to face the sunlight. The origin of the flower’s name is derived from this very trait.

Guide to Growing and Caring for Sunflowers
Choose Healthy Seeds: Select seeds that are free from pests and diseases, preferably sourced from a vigorous and healthy plant.
Planting Time: Sunflowers thrive in warm and sunny weather. They grow well in harsh climates and perform best when exposed to ample sunlight. The ideal planting time is from January to June.
Seed Germination: Before planting, soak the seeds in damp cloth for 5-10 days to increase the germination rate. Once the seeds have sprouted, they can be planted. Be careful not to let the sprouts grow too long before planting, as this can cause damage to the delicate roots.
Planting Process: Prepare furrows for planting, ensuring a distance of 30-90cm between each furrow, depending on the size of the plants. Maintain a distance of 15-20cm between each seed. This ensures optimal growth conditions.
Watering: Regular watering is essential, especially in hot and dry conditions. Water the plants thoroughly in the early morning, providing enough moisture to last throughout the day.
Staking: As the sunflowers grow taller, reaching a height of 30-50cm, it is crucial to provide support by staking the plants. This helps them grow straight and prevents them from toppling over.
Care and Maintenance: Regularly remove weeds and provide fertilizer at regular intervals to promote healthy growth. Use NPK 16-16-8 fertilizer every two weeks after the seedlings reach a height of 40-50cm. Once the plants start to flower, switch to NPK 16-8-16 fertilizer to increase potassium levels, promoting larger and more vibrant blooms.
