Meet Curly Parsley
A decorative parsley with tightly ruffled leaves that makes an excellent garnish and attractive garden border plant. While milder in flavor than flat-leaf parsley, curly parsley adds a fresh, clean taste and appealing texture to dishes. It holds up better in cold weather than flat-leaf varieties and is easier to chop finely.
When to plant Curly Parsley
Soak curly parsley seeds in warm water for 24 hours before sowing to soften the hard seed coat. Some gardeners pour just-boiled water over seeds to further speed germination. Sow 1/4 inch deep in moist seed-starting mix, planting generously as germination rates average 50-60%. Keep soil at 65-70°F and mist regularly. Seeds take 14-28 days to sprout. Once seedlings have two sets of true leaves, thin to the strongest seedling per cell. Harden off over 7-10 days before transplanting outdoors.

How to grow Curly Parsley
Curly parsley is a biennial herb typically grown as an annual, prized for its decorative ruffled leaves and clean flavor. Start seeds indoors 8-10 weeks before the last frost, soaking them in warm water for 24 hours to break dormancy. Sow seeds 1/4 inch deep and maintain soil temperature around 65-70°F. Germination takes 2-4 weeks, similar to flat-leaf varieties.
Transplant seedlings outdoors after the last frost, spacing them 8-10 inches apart in rich, well-drained soil. Curly parsley is more cold-tolerant than flat-leaf types and can withstand light frosts, making it an excellent choice for extending the growing season in cooler climates. It performs well in both full sun and partial shade.
Curly parsley makes an outstanding edging plant for herb and flower gardens due to its dense, attractive growth habit. Keep soil consistently moist and apply a layer of mulch to retain moisture. The tightly curled leaves are less prone to splashing soil during rain, resulting in cleaner harvests compared to flat-leaf varieties.

Curly Parsley's best neighbours
Curly parsley shares the companion planting benefits of all parsley varieties. Plant near tomatoes and asparagus for mutual benefit, as parsley attracts predatory insects that control common vegetable pests. Its dense, decorative foliage makes it an attractive living border for vegetable beds. Curly parsley planted near roses helps attract hoverflies that consume aphids. Keep away from mint, which spreads aggressively and will overwhelm parsley plantings.
Tomato belongs beside it. Lettuce doesn't.

Feed it well
Curly parsley grows best in fertile, well-drained soil with a pH of 6.0-7.0. Prepare beds with 2-3 inches of compost before planting. Apply a balanced liquid fertilizer (10-10-10) every 3-4 weeks, or use fish emulsion for organic growing. Curly parsley benefits from slightly more nitrogen than flat-leaf varieties to support its denser leaf growth. In containers, use premium potting soil and feed biweekly with diluted liquid fertilizer throughout the growing season.

From seed to harvest, stage by stage
Seed Germination
Parsley seeds are famously slow and erratic germinators. The small, ridged seeds contain natural germination inhibitors in their seed coat that must be broken down before the embryo can emerge. Under optimal conditions of consistent moisture and temperatures around 18-22°C (65-72°F), the tiny white radicle root emerges after 14-21 days, followed by a slender hypocotyl pushing the two narrow, strap-like cotyledon leaves above the soil surface.
Seedling Development
The first true leaves appear as small, slightly lobed leaves quite different from the mature curled foliage. Successive leaves become progressively more divided and begin to show the characteristic curling and ruffling of the curly variety. Growth is slow during this phase as the plant invests heavily in developing a deep, sturdy taproot that will sustain it through two growing seasons.
Rosette Formation
The plant develops its signature rosette growth habit, producing a dense whorl of deeply divided, tightly curled leaves from a central crown. The taproot deepens and thickens, storing energy reserves. Leaf production accelerates as the root system becomes established, and the plant begins to form the compact, mounded shape characteristic of curly parsley — typically reaching 20-30 cm in height and spread.
Mature Production
The plant reaches full maturity with a lush, dense mound of tightly ruffled dark green foliage. Leaf production becomes rapid and sustained, with new stems continuously emerging from the central crown to replace harvested ones. The deep taproot allows the plant to tolerate brief dry spells and access nutrients from deep in the soil. In mild climates, production continues through autumn and winter with some slowing during the coldest months.
Bolting and Flowering (Second Year)
As a biennial, parsley enters its reproductive phase in the second growing season. The central crown elongates rapidly into a tall, branching flower stalk reaching 60-90 cm, topped with compound umbel inflorescences bearing tiny yellow-green flowers. The leaves become sparser and develop a stronger, sometimes bitter flavor. Flowers attract a wide range of beneficial insects including hoverflies, parasitic wasps, and ladybugs. After pollination, small, ridged seeds develop and mature to brown.
Soak seeds in warm water for 12-24 hours before planting to speed germination. Sow seeds 5-8 mm deep and keep the soil consistently moist — never let the surface dry out during the long germination period. Covering trays with a humidity dome or damp newspaper helps maintain moisture. Be patient; germination can take up to 4 weeks.

Harvesting Curly Parsley
Harvest curly parsley by cutting outer stems at the base when plants have at least three leaf segments per stem. The tightly curled leaves trap less dirt than flat varieties, making them cleaner at harvest. Cut regularly from the outside of the plant to encourage new growth from the center. For garnishing, harvest just before use to maintain the crisp, decorative appearance. Curly parsley is more resilient to repeated cutting than flat-leaf types and recovers quickly after a heavy harvest.

Storage & Preservation
Curly parsley stores well wrapped in damp paper towels inside a plastic bag in the refrigerator for up to three weeks, longer than flat-leaf varieties due to its sturdier leaf structure. Freeze by spreading whole sprigs on a baking sheet, then transferring to freezer bags. The curled texture does not hold up as well when thawed, so frozen curly parsley is best used in cooked dishes. Dry in a dehydrator at 95°F or air-dry by hanging bundles upside down in a warm, airy space.

Troubleshooting Common Problems
The biggest challenge with curly parsley is slow, erratic germination. Soaking seeds and bottom watering consistently helps overcome this. The curled leaves can trap moisture and harbor fungal issues in humid climates, so ensure adequate spacing for airflow. Plants may appear stunted if grown in heavy clay soil without amendment. Bolting in the second year is natural, but first-year bolting indicates heat stress or root disturbance. Pale leaves usually signal nitrogen deficiency.
Growing Tips
- Pre-soak parsley seeds in warm water for 12-24 hours before planting to leach out germination-inhibiting compounds in the seed coat. Some gardeners pour boiling water over the seeds and let them soak overnight — this can reduce germination time from 4 weeks to 10-14 days.
- Start seeds indoors 8-10 weeks before the last frost date to get a head start on the long germination and establishment period. Transplant seedlings outdoors after hardening off, once night temperatures reliably stay above -2°C (28°F).
- Plant in rich, moisture-retentive soil amended with plenty of compost. Parsley has a deep taproot and prefers consistently moist but well-drained conditions. Sandy soils dry out too quickly; amend with organic matter to improve water retention.
- Choose a position with full sun to partial shade. In hot climates (zones 9+), afternoon shade prevents stress and delays bolting. In cooler zones, full sun produces the most vigorous growth and the darkest, most flavorful foliage.
- Harvest by cutting outer stems at the base of the plant, leaving the inner crown to continue producing new growth. Never harvest more than one-third of the plant at once. This cut-and-come-again method keeps the plant productive for months.
- Feed regularly with a nitrogen-rich fertilizer or compost tea every 3-4 weeks to sustain continuous leaf production. Parsley is a moderate feeder that responds well to consistent nutrition — yellowing lower leaves often indicate a need for more nitrogen.
- Grow parsley in containers at least 20 cm deep to accommodate its long taproot. Use a quality potting mix and ensure drainage holes are adequate. Container parsley needs more frequent watering and feeding than garden-grown plants.
- Companion plant parsley with tomatoes, asparagus, and roses — it is reputed to improve the vigor and flavor of neighboring plants. Avoid planting near lettuce and other Apiaceae family members like carrots, dill, and celery to reduce shared pest and disease pressure.
- Protect overwintering plants with a thick layer of straw or leaf mulch over the crown before the first hard freeze. In zones 5-7, parsley reliably overwinters with mulch protection and resumes growth early in spring before bolting in late spring.
- If parsley worm caterpillars (black swallowtail butterfly larvae) appear, consider relocating them to a sacrificial dill or fennel plant rather than killing them. These striking caterpillars become beautiful native butterflies and rarely cause serious damage to established parsley plants.

Where Curly Parsley comes from
Curly parsley (Petroselinum crispum var. crispum) belongs to the Apiaceae family and traces its origins to the central and eastern Mediterranean region, with wild ancestors growing on rocky hillsides and coastal cliffs across southern Italy, Greece, Sardinia, and the broader eastern Mediterranean basin. Archaeological and literary evidence indicates that parsley was first recognized by ancient civilizations not as a food but as a ceremonial and medicinal plant, with records of its use dating back over 2,000 years.
The ancient Greeks held parsley in solemn regard, associating it with death and the afterlife. They wove parsley into funeral wreaths, decorated tombs with its foliage, and crowned victors at the Nemean and Isthmian funeral games with parsley garlands — a tradition that preceded the more famous olive and laurel crowns. The Greek name 'petroselinon,' meaning 'rock celery,' reflects the plant's natural habitat on stony Mediterranean terrain and gives us the modern botanical name Petroselinum. The Romans were instrumental in transitioning parsley from ceremonial plant to culinary herb, incorporating it into sauces, salads, and cooked dishes throughout the expanding empire.
During the medieval period, parsley spread across Europe through monastic herb gardens and became firmly established in the cuisines of France, Germany, and England. The curly-leaved variety we know today was likely selected and developed during the medieval and early Renaissance periods, as European gardeners favored its ornamental, ruffled foliage over the flat-leaved form — partly for its decorative appeal and partly because the curled leaves helped distinguish edible parsley from the dangerously similar and toxic poison hemlock and fool's parsley. This selection for curly leaves represents one of the earliest examples of breeding an herb for both safety and aesthetics. By the 16th and 17th centuries, curly parsley had become one of the most widely cultivated herbs in European kitchen gardens and was carried to the Americas, Africa, and Asia by colonial settlers and traders, where it established itself in local cuisines worldwide.
