Buzz the Bee in the Sunflower Jigsaw Puzzle

Sunflowers originated in North America and were cultivated by indigenous people for food, oil, and medicine. Spanish explorers brought them to Europe in the 16th century where they became ornamental plants. Russia began growing sunflowers commercially in the 18th century, primarily for oil. In the late 19th century, Russian immigrants brought sunflower seeds to the US where they quickly became popular for oil and birdseed. Sunflowers are now widely grown in the US, Russia, and Ukraine. They are a popular symbol of happiness and are associated with Vincent van Gogh's paintings.
