Vietnamese Coriander is a perennial culinary herb, grown for the flavor it brings to the kitchen, ready to harvest about 60 days after planting. It's hardy across USDA zones 9 through 11, stands up to deer and grows just as well in a container as in the ground. Its summer flowers are a modest draw for honeybees, even though the harvest is the prize.

What Vietnamese Coriander is
Vietnamese Coriander grows as a perennial and reaches around a foot and a half at maturity. It blooms pink in summer. It's also deer-resistant and well suited to containers.
How to grow Vietnamese Coriander
Vietnamese Coriander grows in USDA zones 9 through 11 and is ready to harvest about 60 days after planting. Vietnamese Coriander does best in part sun — at least 4 hours of direct sun a day — and soil from pH 5.5 to 7.5, on consistently moist ground. It needs around 3,000 growing degree days to mature and a growing season of at least 120 frost-free days, which is why climate matters as much as soil.

Start the season right
Plant vietnamese coriander in part sun with at least 4 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Vietnamese Coriander prefers pH 5.5 to 7.5 (Growable Ground Plant Database). 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. Match watering to the plant's drainage preference and your local rainfall.
Harvest at maturity
Vietnamese Coriander is ready about 60 days after planting. Snip sprigs as you need them — regular cutting keeps the foliage tender and slows it bolting to flower.
Where Vietnamese Coriander thrives
Vietnamese Coriander is hardy across USDA zones 9 through 11. 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 9–11 spans average winter lows from 20°F to 50°F (USDA PHZM 2023). Across the 50 states and DC, that band covers none outright but splits 17 down the middle — and which side of that line your land sits on changes the answer.

Where Vietnamese Coriander stands, state by state
Vietnamese Coriander is rated for zones 9–11 — a cold floor USDA puts at 20 to 30°F. Across the 50 states and DC, 0 sit fully inside that band, the line runs through 17 more, and 34 sit outside it — and inside every split state, the same line runs on at county grain.

State zone extents: USDA Plant Hardiness Zone Map (PHZM) 2023. A zone is a 10°F band of average annual extreme minimum temperature, so a state that splits the band contains the boundary — its own page draws the county line, and a parcel report resolves which side your land sits on.

Before you harvest vietnamese coriander, 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 vietnamese coriander for food. Our free screen reads 9 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 Vietnamese Coriander
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 Vietnamese Coriander in my zone?
Vietnamese Coriander grows in USDA hardiness zones 9 through 11 (USDA PHZM 2023). Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
How long does Vietnamese Coriander take to grow?
Vietnamese Coriander is ready to harvest about 60 days after planting. Your local frost dates and soil temperature move that window earlier or later.
When should you plant Vietnamese Coriander?
Most growers plant vietnamese coriander after the last spring frost, once the soil has warmed, leaving enough of the season for its 120-day frost-free need. Your local frost dates set the exact window — a Growable Ground report reads them for your address.
How much sun does Vietnamese Coriander need?
Vietnamese Coriander 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 Vietnamese Coriander need?
Vietnamese Coriander prefers soil pH 5.5 to 7.5, on consistently moist ground (Growable Ground Plant Database). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Vietnamese Coriander attract pollinators?
Yes — vietnamese coriander's flowers are a modest nectar source for honeybees.
Is Vietnamese Coriander safe for pets?
Vietnamese Coriander is not known to be toxic to dogs or cats based on available data. Always supervise pets around new plantings. (Source: ASPCA.)
