Common sunflower

What does Common sunflower look like?

The common sunflower is a tall, rough-stemmed annual plant that can reach up to 3 metres high, with some records showing even taller specimens. Its broad, heart-shaped leaves are rough and coarsely toothed. The plant produces a single large flower head, often 7.5–12.5 cm wide, made up of many small florets. The outer ray florets look like petals and are usually yellow, but can also be red or orange. The center is packed with disk florets that mature into seeds.

Where does Common sunflower come from?

The common sunflower was first domesticated in the Americas, with evidence from both Mexico and the southeastern United States dating back thousands of years. Native Americans cultivated it as a crop, and it held symbolic meaning for several peoples. Spanish explorers brought sunflower seeds to Europe in the 16th century, where the plant became popular for its oil and seeds. Today, sunflowers are grown across the world, especially in Russia and Ukraine, which lead in production.
