Parsnips are cold-tolerant and can be grown in many regions. However, they prefer a cool and humid climate and thrive best in regions with mild winters and rainy summers. In Europe, parsnips are grown mainly in northern and western regions. In Germany, the Netherlands, Belgium and France, they are among the most important root vegetables. In North America, regions with temperate climates, such as the Pacific Coast, the regions around the Great Lakes, and the Northeast, are best suited for growing parsnips. In Asia, parsnips are grown mainly in Japan, China and Korea.
