Spinacia oleracea
Spinach (Spinacia oleracea) is an edible flowering plant in the family of Amaranthaceae. It is native to central and southwestern Asia. It is an annual plant (rarely biennial), which grows to a height of up to 30 cm. Spinach may survive over winter in temperate regions.
Spinach is thought to have originated in ancient Persia (modern Iran). Arab traders carried spinach into India, and then the plant was introduced to China. The earliest record of spinach is in Chinese, stating that it was introduced into China from Nepal (probably in 647 AD). [2]
In AD 827, the Saracens introduced spinach to Sicily. The first written evidence of spinach in the Mediterranean are in three tenth-century works, the medical work by al-Razi (known as Rhazes in the West) and in two agricultural treatises, one by Ibn Wahshiya and the other by Qustus al-Rumi. Spinach became a popular vegetable in the Arab Mediterranean and arrived in Spain by the latter part of the twelfth century where the great Arab agronomist Ibn al-‘Awwam called it the “captain of leafy greens.” Spinach was also the subject of a special treatise in the eleventh century by Ibn Hajjaj. [3]
The prickly-seeded form of spinach was known in Germany by no later than the 13th century, though the smooth-seeded form was not described till 1552. (It is the smooth-seeded form that is used in modern commercial production). [4]
Spinach first appeared in England and France in the 14th century, probably via Spain, and it gained quick popularity because it appeared in early spring, when other vegetables were scarce and when Lenten dietary restrictions discouraged consumption of other foods. Spinach is mentioned in the first known English cookbook, The Forme of Cury (1390) where it is referred to as spinnedge and/or spynoches. [5] Smooth-seeded spinach was described in 1552. [6]
In 1533, Catherine de’Medici became queen of France; she so fancied spinach that she insisted it be served at every meal. To this day, dishes made with spinach are known as “Florentine” because Catherine came from Florence, Italy. [7] Because spinach was then regarded as having high iron content, wine fortified with spinach juice was used to treat French soldiers weakened by hemorrhage [8]
There are three basic types of spinach:
Savoy has dark green, crinkly and curly leaves. It is the type sold in fresh bunches in most supermarkets. One heirloom variety of savoy is Bloomsdale, which is somewhat resistant to bolting.
Flat/smooth leaf spinach has broad smooth leaves that are easier to clean than savoy. This type is often grown for canned and frozen spinach, as well as soups, baby foods, and processed foods.
Semi-savoy is a hybrid variety with slightly crinkled leaves. It has the same texture as savoy, but it is not as difficult to clean. It is grown for both fresh market and processing. Five Star is a widely grown variety and has good resistance to running up to seed.

The leaves are alternate, simple, ovate to triangular-based, very variable in size from about 2-30 cm long and 1-15 cm broad, with larger leaves at the base of the plant and small leaves higher on the flowering stem. The flowers are inconspicuous, yellow-green, 3-4 mm diameter, maturing into a small, hard, dry, lumpy fruit cluster 5-10 mm across containing several seeds.
