Sunflower became very popular as a cultivated plant in the 18th century. Most of the credit is given to Peter the Great. The plant was initially used as an ornamental, but by 1769 literature mentions sunflower cultivated by oil production. By 1830, the manufacture of sunflower oil was done on a commercial scale. The Russian Orthodox Church increased its popularity by forbidding most oil foods from being consumed during Lent. However, sunflower was not on the prohibited list and therefore gained in immediate popularity as a food.
