Celery, common name for a biennial herb of the parsley family, a native of Europe but now widely grown throughout the world. The stalks, about 30 to 76 cm (about 12 to 30 in) high in cultivated varieties, are eaten, raw or cooked, as a vegetable or salad. When allowed to grow naturally, the stalks are greenish in color and slightly bitter in taste. They are often blanched during the last stages of their growth by preventing access of sunlight except to the leaves; this process removes the color and the bitter taste, but also some of the vitamins. If allowed to grow a second year, celery sends up flower stalks about 61 to 91 cm (about 24 to 36 in) tall with small white flowers in umbels. The dried fruit of celery is used as a condiment alone under the name of celery seed or ground and mixed with salt under the name of celery salt. Celery seed is also used in pharmacy as a sedative or to disguise the flavor of other drugs. Celery is subject to attack by several blights, by the tar...

Spinach, common name for an annual crop plant, of the goosefoot family, grown for its nutritious and savory leaves. Probably native to southwestern Asia, spinach was introduced to Europe by the 12th century. It became cultivated worldwide and received sudden popularity in the 1920s when nutritionists found it contained iron, vitamin A, and vitamin B2, or riboflavin. Two varieties of spinach are now grown. Wrinkled, or savoy, spinach can be packaged and shipped without wadding or spoiling and is marketed fresh. Smooth-leaved spinach can be easily washed and is marketed frozen or canned. Spinach leaves are picked from the immature plant when in the form of a rosette close to the ground. Because extended daylight and hot temperature cause the plant to bolt, or draw growth away from the leaves and into a tall, central flower stalk, spinach is best cultivated in cool climates during spring or fall, or in warm climates during winter. Most spinach in the United States is now produced i...
