Girasoles have a rich history that dates back thousands of years. Originally cultivated by indigenous peoples in North America, sunflowers were valued not only for their beauty but also for their seeds, which were a vital food source.

In the 16th century, Spanish explorers brought girasoles to Europe, where they quickly gained popularity. By the 18th century, sunflowers were being cultivated in gardens across Europe and were even used as a decorative motif in art and architecture. Today, girasoles are grown all over the world, celebrated for their vibrant colors and numerous benefits.
