Celery was popular with the ancient Romans who used it in soups and stews and spread wild celery throughout Europe. Celery is a cool season crop. The dark green outer stalks are stringier and have a stronger flavor than the pale green stalks in the center. Kids can eat organic celery leaves which add celery flavor to salads and soups. Celery seeds are used to flavor salad dressings, sauces, and soups. Kids can grow celery in a container of rich organic soil with a great deal of steady moisture to the roots of the plant. Kids can put a ceramic saucer under a pot with a drip watering system on a battery timer or water daily through a plastic bottle with a hose attached to the bottom of the container, like in the picture above. Kids can pick the outside stalks for a dish and leave the rest of the plant growing. Celery is very low in calories and has a nutrient called phthalide that increases blood flow by relaxing the arteries, reducing high blood pressure, lowering cholesterol levels, and detoxifying the body. Kids love celery sticks filled with peanut butter and toped with raisins for a quick snack.
