Sunflowers are large, bright yellow flowers that are native to North America but are now cultivated all over the world. They belong to the genus Helianthus, which means “sun flower” in Greek, and are named after their characteristic behavior of turning their heads to follow the sun’s movement across the sky.
They are annual or perennial plants that can grow up to 3 meters tall, with large, broad leaves and a single, central flower head that can be up to 30 cm in diameter. The flower head is composed of thousands of individual flowers arranged in a spiral pattern, with the outer flowers being large and showy, and the inner flowers being smaller and fertile.
Also they are used for a variety of purposes, including as a source of food, oil, and birdseed. The seeds of the sunflower plant are particularly valuable, as they are high in protein and healthy fats. Sunflowers are also popular as ornamental plants, and their bright, cheerful appearance makes them a favorite in gardens and floral arrangements.
TYPES OF SUNFLOWERS
There are many different types of sunflowers, with varying characteristics such as size, color, and growth habit.
1) OIL SUNFLOWERS:
Oil sunflower (Helianthus annuus) is a plant species that is widely cultivated for its seeds, which are a rich source of oil. They are annual plants that can grow up to 10 feet (3 meters) tall and they have large, round flower heads that can measure up to 12 inches (30 centimeters) across and are made up of hundreds of small flowers surrounded by bright yellow petals.
Also Oil sunflowers are typically grown in temperate regions around the world, with the largest producers being the United States, Russia, Ukraine, Argentina, and China. They require well-drained soil and plenty of sunlight, and can be grown as a single crop or in rotation with other crops.
The seeds are primarily used for the production of cooking oil, as well as biodiesel. Sunflower oil is a popular oil for cooking and frying, due to its neutral taste and high smoke point.
