The sunflower turns to face the sun as it grows, a behaviour called heliotropism. Native to the Americas, it is now grown worldwide for its edible seeds and healthy cooking oil, and its cheerful yellow heads make it one of the most recognisable flowers on Earth.

💊 Sunflower in the medicine industry
Sunflower seeds and oil are used in food supplements; pollen and petals are studied for anti-inflammatory and antioxidant activity in herbal medicine.
🌱 Growing & care tips
Plant seeds 2 cm deep in full sun after the last frost; thin to 30–45 cm apart. Tall varieties need staking in windy spots, and watering deeply once a week gives the biggest heads. Feed lightly with compost when buds form.
🍽️ How to use it
The seeds are eaten roasted as a snack, pressed into cooking oil, and sprinkled on salads and breads; young flower buds can be steamed like artichokes.
💡 Did you know? Sunflowers follow the sun — young plants turn their heads east to west during the day and return east at night; once mature they settle facing east.
⚠️ Sunflower safety note: Sunflower seeds are safe for most people, but they are high in calories and fat — a small handful is a sensible portion. Very rarely, people allergic to ragweed also react to sunflower seeds.
⚠️ Important: Herbal and plant remedies can interact with medicines. Always ask a doctor or pharmacist before using any plant product for health purposes — especially if you are pregnant, breastfeeding or taking prescription drugs.
