Picture of Parsnip

The parsnip (Pastinaca sativa) is a root vegetable closely related to the carrot and parsley. It is a biennial plant usually grown as an annual. Its long tuberous root has cream-colored skin and flesh and can be left in the ground when mature as it becomes sweeter in flavor after winter frosts. In its first growing season, the plant has a rosette of pinnate, mid-green leaves. If unharvested, it produces its flowering stem, topped by an umbel of small yellow flowers, in its second growing season. By this time the stem is woody and the tuber inedible. The seeds are pale brown, flat and winged.

The parsnip is native to Eurasia. It has been used as a vegetable since antiquity and was cultivated by the Romans, although there is some confusion in the literature of the time between parsnips and carrots. It was used as a sweetener before the arrival in Europe of cane sugar. It was introduced into the United States in the nineteenth century.

The parsnip is usually cooked but can also be eaten raw. It is high in vitamins and minerals, especially potassium. It also contains antioxidants and both soluble and insoluble dietary fiber. It can be cultivated in deep, stone-free soils and is attacked by the carrot fly and other insect pests, viruses and fungal diseases, of which canker is the most serious. In sunlight, handling the stems and foliage can cause a skin rash.
