Parsley is an annual or biennial culinary herb, grown for the flavor it brings to the kitchen, ready to harvest about 75 days after planting. Season length, not a winter zone, decides where it grows. Notably, it stands up to deer and grows just as well in a container as in the ground. Its summer flowers are a moderate draw for honeybees, native bees, and butterflies, even though the harvest is the prize. As a member of the carrot family, give it a fresh bed each year — away from where its relatives just grew — so the soil-borne pests and diseases of the family never get a foothold.

What Parsley is
Parsley grows as an annual or biennial and reaches around a foot and a half at maturity. It blooms yellow in summer. It's also deer-resistant and well suited to containers.
How to grow Parsley
Season length, not a winter zone, decides where parsley grows; it is ready to harvest about 75 days after planting. Parsley does best in part sun — at least 4 hours of direct sun a day — and soil from pH 5.3 to 8.3, on well-drained ground. It needs around 1,100 growing degree days to mature and a growing season of at least 70 frost-free days, which is why climate matters as much as soil.

Start the season right
Plant parsley in part sun with at least 4 hours of direct sun. It grows in the cool halves of the year, so sow it in spring or late summer rather than waiting for midsummer heat.
Match the soil
Parsley prefers pH 5.3 to 8.3 (FAO ECOCROP). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band.
Water steadily
Keep the root zone evenly moist through establishment. A 2–3 inch mulch layer holds moisture without waterlogging.
Harvest at maturity
Parsley is ready about 75 days after planting (Cornell; PrairieMoon). Snip sprigs as you need them — regular cutting keeps the foliage tender and slows it bolting to flower.
Where Parsley thrives
Season length, not a winter zone, decides where parsley grows. Zone is only the starting point, though: the soil pH, drainage, and frost dates on your specific land decide how well it actually does.
A USDA zone is a 10°F band of average annual extreme winter minimum, so zones 5–9 spans average winter lows from -20°F to 30°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 25 outright and splits 25 more down the middle.

Where Parsley stands, state by state
Parsley is rated for zones 5–9 — a cold floor USDA puts at -20 to -10°F. Across the 50 states and DC, 25 sit fully inside that band, the line runs through 25 more, and 1 sits outside it — and inside every split state, the same line runs on at county grain.

Growing guides for parsley
In rotation planning, parsley counts as a Carrot — beds recover best when carrot crops don’t follow each other in the same spot year over year. (Growable Ground derivation — crop-rotation group from botanical family)
Good to know
One caution for pet owners — parsley is toxic to dogs, cats and horses. Keep it out of reach, and call ASPCA Animal Poison Control at (888) 426-4435 in an emergency. (Source: ASPCA.)

Before you harvest parsley, know your soil
Anything you grow to eat takes up what's in the ground it grows in, so it's worth knowing what's documented near you before you plant parsley for food. Our free screen reads 8 federal source types across roughly 1.8M indexed sites and shows which sit near your address and which way they drain. It's a screening estimate from public records and proximity — not a soil test — so a nearby record means a soil test is worth it, not that your soil is unsafe.

How we know this about Parsley
The figures above are cited per row, not per site: the pH band names this plant’s own source column, the three temperature figures each carry their own, and days-to-maturity cites the publication that actually lists it. All of it comes from the Growable Ground Plant Database — a compilation over FAO ECOCROP, USDA PLANTS, and university Extension sources, published openly with per-field provenance.

Frequently asked questions
Can I grow Parsley in my zone?
Parsley is grown as an annual, so a hardiness zone does not decide it — its growing season follows your last and first frost dates. Soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
How long does Parsley take to grow?
Parsley is ready to harvest about 75 days after planting (Cornell; PrairieMoon). Your local frost dates and soil temperature move that window earlier or later.
When should you plant Parsley?
Parsley is a cool-season crop, so it goes in during the cool halves of the year — early spring, and again in late summer for a fall planting — rather than at the height of summer heat. Your local frost dates set the exact window — a Growable Ground report reads them for your address.
How much sun does Parsley need?
Parsley does well in partial sun — around 4 hours of direct sun, and it takes some afternoon shade in stride. That flexibility makes it a good match for a bed the house or a nearby tree shades for part of the day. A Growable Ground report maps how the sun actually falls on your land, hour by hour, so you can set it where the light lines up.
What soil does Parsley need?
Parsley prefers soil pH 5.3 to 8.3, on well-drained ground (FAO ECOCROP). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Parsley attract pollinators?
Yes — parsley's flowers are a solid nectar source for honeybees, native bees, and butterflies. (Source: Pollinator Partnership.)
Is Parsley safe for pets?
Parsley is toxic to dogs, cats and horses. Keep it out of reach, and call ASPCA Animal Poison Control at (888) 426-4435 in an emergency. (Source: ASPCA.)
