Parsley
Petroselinum crispum
Overview
Far more than a plate garnish, parsley is one of the most nutritionally dense herbs available and a foundation of Mediterranean, Middle Eastern, and French cuisine. Flat-leaf (Italian) parsley has the best flavor for cooking, while curly parsley is the classic garnish. It is the main ingredient in tabbouleh and chimichurri, and a host plant for swallowtail butterfly caterpillars.

Growing Conditions
How to Grow Parsley
Parsley (Petroselinum crispum) is a biennial forb/herb that grows to about 12 inches tall and 12 inches wide.
To grow parsley, give it full sun, though it tolerates a little shade. It is hardy across USDA hardiness zones 3–9. Plant it in rich, moist, well-drained soil, at a slightly acidic pH of 6–7. It does best with even, moderate watering.
Exact sowing, transplanting, and harvest months shift by climate zone — the planting calendar below lays them out for cool through hot regions. Its flowers appear from June through August, offering high value to pollinators. It feeds two tables at once: yours and the pollinators’.
Companion Planting & Soil
Parsley grows well alongside tomato, asparagus, corn, rose, and carrot — but keep it clear of lettuce and mint.

Uses
In the Kitchen
In the kitchen, parsley turns up in more than one form: essential in tabbouleh, chimichurri, and gremolata; fresh chopped as finishing herb on virtually any savory dish; stems add depth to stocks and bouquet garni.
Medicinal & Folk Use
In herbal and folk tradition, it has been valued in several ways: exceptionally rich in vitamin K, vitamin C, and iron; traditional diuretic and kidney tonic; chlorophyll-rich natural breath freshener. These are traditional uses, not medical advice.
Beyond the Garden
Parsley earns its keep past the plate, too: host plant for black swallowtail butterfly caterpillars; attracts beneficial insects including tachinid flies.
Safety Notes
Safe in normal culinary amounts. Very large quantities (medicinal doses) should be avoided during pregnancy. Rich in vitamins A, C, K.
