Spinach (Spinacia oleracea) is a leafy green flowering plant native to central and western Asia. Spinach is thought to have originated about 2000 years ago in ancient Persia, from which it was introduced to India and ancient China via Nepal in 647 AD as the "Persian vegetable."

Common Vegetables

In everyday usage, a vegetable is any part of a plant that humans consume as part of a savory meal.

The term "vegetable" is somewhat arbitrary and largely defined through culinary and cultural tradition. It normally excludes other food derived from fruits, nuts, and cereal grains, including seeds such as pulses.
