Parsley

• 1. Introduction

  ›

  Parsley, or garden parsley, carries the scientific name Petroselinum crispum, and it has been quietly anchoring kitchens across Europe, the Middle East, and the Americas for thousands of years. The plant is native to the Balkans, yet it traveled so far and adapted so well that today it is hard to imagine Mediterranean cooking without it. How did a bright green herb from a corner of southeastern Europe become one of the most widely cultivated plants in the world? And why, despite its ubiquity as a garnish, does it hold a far stranger and more complex life than most people ever suspect? The answers reach back to ancient Sardinia, pass through the Anglo-Saxon world, and end up on a Passover table.

  Sardinia is where Linnaeus placed parsley's wild origins, and it is the island from which the herb is believed to have first entered cultivation, somewhere around the 3rd century BC. That is a long history for something so small. From Sardinia, parsley eventually made its way to Britain. The record shows it was first cultivated there in 1548, though literary evidence pushes its English presence back much further, into the Anglo-Saxon period of the Middle Ages. The herb spread across Europe and beyond, naturalizing in climates hospitable enough to sustain it. Its scientific name traces through Latin petroselinum, which itself is a latinization of the Greek word meaning rock celery. The earliest known form of the root word selinon appears in Mycenaean Greek, written in Linear B script, making parsley one of the few herbs whose name can be traced to one of the oldest written languages in European history. The English word parsley arrived as a merger of Old English petersilie and Old French peresil, both deriving from that same Medieval Latin root.

• 3. The Living Plant

  ›

  In temperate climates, garden parsley is a biennial, which means it devotes its first year entirely to building a foundation. It produces a rosette of tripinnate leaves measuring 10-25 cm long, each subdivided into numerous leaflets ranging from 1-3 cm in size. Underneath, a taproot quietly stores energy through the winter. The second year brings transformation: the plant sends up a flowering stem reaching 75 cm tall, crowned with flat-topped umbels 3-10 cm across. Those umbels carry numerous tiny yellow to yellowish-green flowers, each only 2 mm across. After seed maturation, the plant normally dies. The seeds themselves are ovoid and 2-3 mm long, and they are famously slow to germinate, taking four to six weeks. The reason is furanocoumarins in the seed coat, compounds that act as a natural germination inhibitor. The essential oil of parsley contains apiole, a compound that gives the plant some of its characteristic properties. One of the more striking biological features of parsley in the garden is the company it keeps: some swallowtail butterflies use it as a host plant for their larvae, whose caterpillars are black and green striped with yellow dots and feed on the plant for about two weeks before becoming butterflies.

• 4. A Herb With Many Faces

  ›

  The two main groups of parsley cultivated as herbs divide along clear lines. The French, or curly-leaf group, offers a decorative ruffled appearance that makes it the preferred choice for garnishing. The Italian, or flat-leaf group, is said by many to carry a stronger flavor, though that claim is disputed. Flat-leaf parsley also earns points among gardeners for tolerating both rain and sunshine better than the curly variety. A third type, sometimes grown in southern Italy, has thick leaf stems resembling celery. Then there is root parsley, known by the cultivar name Hamburg root parsley, which produces roots far thicker than those of leaf varieties. Root parsley looks similar to parsnip, which is actually one of its closest relatives in the family Apiaceae, but the two taste quite different. Root parsley is rarely used in Britain or the United States, while it remains a staple across central and eastern European cuisines, where it is eaten raw as a snack much like a carrot, or cooked in soups and stews.

  Fresh parsley sprinkled over a dish is a habit shared across central, eastern, and southern Europe, as well as across western Asia. In those regions it finishes soups, rice dishes, grilled meats, and vegetables. Curly parsley, meanwhile, serves largely as a visual accent on plates across much of Europe and the Americas. Flat-leaf parsley is the main ingredient in Italian salsa verde, a condiment that combines parsley with capers, anchovies, garlic, and sometimes bread soaked in vinegar, traditionally served with bollito misto or fish. Gremolata, a simpler mixture of parsley, garlic, and lemon zest, is the classic accompaniment to ossobuco alla milanese, the Milanese veal stew. In France, persillade pairs chopped garlic with chopped parsley as a foundational mixture. Parsley is also central to several Middle Eastern preparations, including Lebanese tabbouleh and falafel, where it contributes the green color to the interior of the fritter. The Iranian stew ghormeh sabzi counts parsley among its main components. In Brazil, freshly chopped parsley and freshly chopped scallion together form cheiro-verde, literally "green aroma", a seasoning used across a vast range of Brazilian dishes from meats to soups to rice. Cheiro-verde is sold in markets as a bundled package of both herbs together. Parsley seeds, less commonly discussed, also find their way into cooking, delivering a stronger parsley flavor than the leaves alone.

• 6. Nutrition and Ritual

  ›

  Fresh parsley is 88% water, with 6% carbohydrates, 3% protein, and 1% fat in its composition. A 100-gram serving supplies 36 calories. That same reference amount qualifies parsley as a rich source of vitamin K, vitamin C, vitamin A, folate, and iron, meaning each provides 20% or more of the daily recommended value. Fresh parsley also contains apigenin and myricetin, two naturally occurring plant compounds. One of the herb's most cited folk properties is its ability to neutralize the odors associated with garlic when the two are consumed together. Parsley also carries one notable ritual role: it is a component of the traditional Seder plate at Passover, eaten to symbolize the flourishing of the Jewish people after first arriving in Egypt. Excessive consumption carries a medical caution, specifically for pregnant women. While normal culinary amounts are considered safe, consuming parsley in very large quantities may produce uterotonic effects. The plant grows best in moist, well-drained soil with full sun, at temperatures between 22 and 30 degrees Celsius, typically grown from seed despite that slow germination window of four to six weeks.
