Plain or Single Parsley Seeds – Heirloom Non-GMO

Plain or Single Parsley Seeds

Grow a classic culinary herb with Plain or Single Parsley, a smooth, dark green plain-leaf type of Petroselinum crispum. This heirloom, Non-GMO, open-pollinated variety has a fresh, mild herbal flavor with a slightly peppery character and works well in garden beds, raised beds, containers, and greenhouse plantings.

Parsley rewards a little patience at the beginning. Its seed naturally germinates more slowly than many common herbs, but established plants produce a steady supply of flavorful leaves that can be harvested throughout the growing season.

Growing Overview

Parsley can be direct sown in spring after the soil begins to warm or started indoors several weeks before transplanting. Soaking seeds overnight before sowing can help with the naturally slow germination process.

Sow about 1/4 inch deep and keep the seedbed consistently moist. Under favorable conditions, germination commonly takes about 14–28 days, with soil temperatures around 65–75°F providing suitable conditions.

Space established plants about 6–8 inches apart. Full sun supports strong growth, while partial shade can be helpful in warmer climates. Fertile, well-drained soil and regular moisture encourage steady leaf production.

Harvest & Enjoy

Begin harvesting once plants have developed enough foliage to continue growing after cutting. Remove outer stems near the base and leave the younger center growth intact for continued production.

Plain-leaf parsley is useful far beyond garnish. The fresh leaves work well in soups, salads, sauces, vegetables, meat dishes, seafood, and herb mixtures and can also be dried for later use.

What to Expect

Parsley is naturally slower to germinate than many garden herbs. Soil that dries out during germination can reduce or delay emergence, so maintaining even moisture is especially important during the first several weeks.

Although many seed catalogs describe parsley as an annual crop, the plant is botanically biennial. It normally produces leafy growth in its first season and, if it survives winter, may flower and produce seed during its second year.

Frequently Asked Questions

Is Plain or Single Parsley a flat-leaf parsley?

Yes. Plain or Single is a smooth, plain-leaf parsley type rather than a tightly curled parsley.

Why does parsley take so long to germinate?

Parsley seed naturally germinates slowly and somewhat unevenly. Warm but not hot soil, steady moisture, and soaking the seeds overnight before sowing can help establish more consistent conditions.

Can I grow parsley in a container?

Yes. Use a container with good drainage and place it in full sun or partial shade. Keep the potting mix consistently moist without leaving it saturated.

Can parsley grow indoors?

Yes. Parsley can be grown indoors when it receives bright light, sufficient moisture, and regular care.

How should I harvest parsley?

Cut mature outer stems near the base of the plant instead of removing only leaf tips. Leaving the central growth intact allows the plant to continue producing new stems.
