Botanically termed as Helianthus Annuus, the sunflower is an annual flowering plant in Asteraceae family. This plant is famous for its extremely large and vividly yellow blooms. A native to South America, it was domesticated around 1500 BC. They are now cultivated worldwide for their oil-rich and highly nutritious seeds.
Safflower is commercially cultivated for vegetable oil extracted from the seeds. Plants are 30 to 150 cm (12 to 59 in) tall with globular flower heads having yellow, orange, or red flowers. Each branch will usually have from one to five flower heads containing 15 to 20 seeds per head.
