Grow Petroselinum crispum, commonly known as Parsley, for its aromatic culinary leaves. This low-maintenance annual thrives in partial shade.
Complete Plant Information
Overview
Petroselinum crispum, universally recognized as Parsley, is an indispensable culinary herb globally valued for its aromatic, edible leaves. This popular biennial is typically cultivated as an annual in many climates, offering dense mounds of finely divided, rich dark green foliage perfect for kitchen use or garnishing. Its low maintenance requirements and adaptability make it a staple for both new and experienced gardeners.
Native to the region spanning Greece to Slovenia and Morocco, Parsley fits well into diverse garden settings, provided it receives consistent moisture and rich soil. While it can tolerate full sun, plants perform optimally when shielded from the hottest afternoon rays. Gardeners prize Petroselinum crispum not just for flavor, but also for its role as a larval host plant for the striking black swallowtail butterfly.
Whether you choose the curly, flat-leaved, or root variety, Parsley provides strong visual texture ranging from 0.75 to 1 foot tall and wide. Its ease of culture, especially when grown for its annual harvest, secures its place as a reliable, functional landscape feature.

How to Grow
Container plants and starter plants of Parsley should be introduced into the garden after the danger of the last spring frost has passed, spaced approximately 8 to 12 inches apart. While sowing seeds directly outdoors is possible after the last frost date, germination for Petroselinum crispum is notoriously slow and uneven, making indoor starting preferable. For the best results, start seeds indoors 6 to 8 weeks prior to the last spring frost date.
This herb demands average, consistently moist, well-drained soil, preferring it to be rich in organic matter. Never allow the soil around your Parsley to dry out completely, as this stresses the plant. While it enjoys full sun, it benefits significantly from light shade during the hot summer months; plants can languish in intense heat and humidity.
Maintenance is generally low. Harvest outer leaves as needed to encourage fresh growth from the center. If you wish to overwinter containers or carefully dug-up plants, bring them indoors before the first fall frost and place them in a cool area with bright light or supplemental growing lights. Remember that if left to flower in its second year, the leaves of Petroselinum crispum will lose significant flavor.
Landscape Uses
Parsley is exceptionally versatile, excelling in almost any space where consistent moisture can be provided. It functions beautifully as an edging plant along pathways or garden beds, offering a rich green border that is both aesthetic and edible. Consider integrating it into herb gardens for easy access during cooking.
For visual impact, plant clumps of curly leaved Parsley in containers or hanging baskets, allowing the foliage to spill attractively over the edges. It pairs well with other compact herbs like chives or thyme. As an attractive landscape plant, its dense, mounded habit also provides excellent contrast against taller, sparser foliage plants.
Its primary suggested use remains centered on culinary applications—chopping the aromatic leaves fresh for use in salads or traditional dishes, or drying them for later preservation.

Noteworthy Characteristics
Petroselinum crispum, called parsley, is a culinary herb that is native to Europe and the Mediterranean. It is now grown world-wide for its is aromatic edible leaves which may be used fresh or dried in soups, salads and a wide variety of other food dishes (e.g., potatoes, fish, stews, vegetables, omelets). The dark green leaves are finely divided, and the plant typically forms a clump up to 12 inches wide. Historically, three main types are recognized: curly leaved (var. Crispum), Italian flat-leaved (var. Neapolitanum), and Hamburg (var. Tuberosum), the latter grown for its edible root.
Tolerances
- Good for cut flowers
Potential Problems
Parsley generally avoids severe disease or insect issues, contributing to its low maintenance rating. Watch for fungal issues like Septoria leaf spot and stem rot, which are often favored by overly wet conditions or poor airflow. Pests to monitor for include the carrot weevil, flea beetles, leafhoppers, and tarnished plant bugs. Maintaining consistent soil moisture and planting in spring weather that is naturally cooler will mitigate much of this risk.

Wildlife Benefits
As a member of the Apiaceae family, Parsley foliage and flowers attract beneficial insects and provide critical resources for local fauna. Most notably, the leaves of Petroselinum crispum serve as a necessary larval food plant for the magnificent black swallowtail butterfly. Providing this host plant supports the complete life cycle of these important pollinators in your ecosystem.
Companion Planting
Due to its moderate height and love for consistently moist conditions, Parsley mixes well with companion plants that share similar needs, such as lettuce, chives, and tomatoes (which appreciate the shade provided during peak summer heat). Avoid planting too closely alongside carrots or other members of the same vegetable family, as this can exacerbate pest issues like the carrot weevil. Utilizing the clump-forming nature of Parsley in succession planting schemes keeps the garden productive throughout the season.
