Generally — Most Areas
goldenseal (zones 3-8) suits most of Mississippi (7b-9b) — zones 7-8 are in range, and the rest of the state is the exception.
Your yard isn't the whole zone.
Mississippi spans zones 7b-9b, but your yard sits in exactly one — and slope, tree cover, and cold-air pockets nudge it further. Enter your address and we'll score goldenseal against your parcel's actual hardiness, soil, and sun.

When to Plant Goldenseal in Mississippi
The frost window
Across Mississippi, the last spring hard freeze (28°F) clears between Feb 17 and Mar 3, and the first fall hard freeze lands between Nov 21 and Nov 30 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 263-day window you can count on — up to 286 days on a mild site in a kind year. That marks the hard freeze, not the last light frost, so tender transplants usually wait another 2-3 weeks.
Winter standing
Mississippi runs as cold as USDA zone 7, and no sourced winter-hardiness floor is on record for goldenseal, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether goldenseal is a permanent planting or a replant-every-spring crop for you turns on your own zone within Mississippi; check its hardiness range against that before treating it as long-lived ground.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: USDA PLANTS Database. Your site's own frost dates can run earlier or later than the state range — a parcel report pins them down.
Growing Season Fit
The zone check says goldenseal survives winter in part of Mississippi, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Goldenseal wants 120+ frost-free days; a typical Mississippi site sees ~273 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
GDD and chill-hour figures are computed from PRISM 1991-2020 monthly climate normals; frost-free days from NOAA Regional Climate Centers ACIS, 1991-2020. Each is the state median across its counties (P25/P75 span the within-state spread). Hardiness-zone range is USDA PHZM 2023.
Soil + Drainage Fit
Goldenseal likes near-neutral soil (pH 5.5-7). That's the common-ground band across Mississippi's loess and alluvial clay — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 6 and 7 — worth knowing before you decide whether a Mississippi soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Mississippi site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

- Plant Zones: 3-8 (USDA PLANTS Database)
- State Zones: 7b-9b (USDA ARS PHZM 2023)

What Else to Consider for Goldenseal in Mississippi
Zone compatibility tells you about winter cold survival — but Mississippi growers also need to think about:
Extreme summer heat and humidity
Heavy alluvial clay in the Delta region
Frequent severe storms and flooding
What to actually do about these — and the constraints that apply to every Mississippi grower, not just goldenseal — is covered on the Mississippi growing guide.
Timing shifts within Mississippi
Goldenseal needs about 120 days of frost-free season to complete its cycle. Even Tishomingo County — Mississippi’s shortest season at 232 frost-free days — clears that by 112 days, so season length isn’t the constraint anywhere in Mississippi. What varies is your own parcel.
Across Mississippi’s 82 counties the frost-free season runs from 232 days in Tishomingo County to 309 days in Harrison County — a spread of 77 days, which is why a single statewide planting date misleads. The median Mississippi county sees 273 frost-free days, leaving goldenseal about 153 days of slack on a typical parcel — room for a second sowing where the season runs long.
County last-freeze dates and frost-free day counts: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). Goldenseal's 120-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Where in Mississippi Fits Best
Even within Mississippi's zones 7b-9b, county microclimates differ enough to change what thrives. These counties carry the closest zone match for goldenseal (USDA PHZM 2023):
Pollinator + Wildlife Value
Goldenseal draws native bees (low value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, goldenseal can only work that bloom inside Mississippi's frost window — roughly 273 days, opening after the last 28°F freeze (Feb 17 - Mar 3) and closing at the first (Nov 21 - Nov 30), per NOAA Regional Climate Centers ACIS, 1991-2020.
Mississippi Cooperative Extension
For Mississippi-specific cultivar recommendations, planting calendars, and pest pressure for goldenseal, the canonical source is Mississippi State University Extension Service. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Goldenseal native to Mississippi?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Goldenseal as native to Mississippi. Planting it supports the pollinators and wildlife that evolved alongside it.

Common Questions About Growing Goldenseal in Mississippi
When can I plant Goldenseal in Mississippi?
Mississippi's last spring hard freeze (28°F) clears between Feb 17 and Mar 3, and the first fall hard freeze lands between Nov 21 and Nov 30 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Goldenseal, so this page does not state whether it overwinters in Mississippi and publishes no fall establishment date for it — check its hardiness range against your own zone before treating it as a permanent planting.
What hardiness zone is Goldenseal grown in across Mississippi?
Mississippi spans USDA hardiness zones 7b-9b (USDA ARS PHZM 2023). Goldenseal carries a range of zones 3-8, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Mississippi site have?
A typical Mississippi site sees ~273 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Goldenseal needs 120+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Goldenseal native to Mississippi?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Goldenseal as native to Mississippi. Planting it supports the pollinators and wildlife that evolved alongside it.
How should I amend the soil for Goldenseal in Mississippi?
Goldenseal prefers pH 5.5-7 and well (dry spells) drainage (Growable Ground Plant Database). That sits in the common-ground band across Mississippi soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
Will Goldenseal actually grow on my specific land in Mississippi?
