Unlikely — Zone Mismatch
clove (zones 11-12) does not overlap with South Carolina's zone range (7a-9b). Growing outdoors is unlikely without significant protection.
2 zones short — what would close it
Clove is hardy to zone 11, and the warmest ground in South Carolina is zone 9 — 2 zones short. Planted in open ground it will not survive a South Carolina winter. To grow it here, grow clove under glass — a greenhouse is the only lift this wide the engine models.

When to Plant Clove in South Carolina
The frost window
Across South Carolina, the last spring hard freeze (28°F) clears between Feb 27 and Mar 12, and the first fall hard freeze lands between Nov 23 and Dec 1 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 256-day window you can count on — up to 277 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
South Carolina runs as cold as USDA zone 7, and no sourced winter-hardiness floor is on record for clove, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether clove is a permanent planting or a replant-every-spring crop for you turns on your own zone within South Carolina; check its hardiness range against that before treating it as long-lived ground.
Timing tuned to sub-state frost dates — Chester County, not the statewide average.
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 clove does not survive a South Carolina winter in the ground. The season figures below measure a different question — whether it could finish a season here at all — and they only bear on South Carolina under protection.
Frost-free days
Clove wants 150+ frost-free days; a typical South Carolina site sees ~265 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
Growing degree days
Clove needs ~5500 GDD (base 50°F) to ripen. The state median runs ~5233 GDD (from PRISM 1991-2020 climate normals), so South Carolina's typical season runs short on heat — pick a south-facing site and consider season extension.
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
Clove tolerates a wide pH range (pH 4.5-8) — 3.5 units, acid ground through alkaline — so soil acidity is rarely what limits it in South Carolina. A soil test is still worth having, but for what else it tells you about this site, not to clear this plant. It will grow across that whole span, but it does best between pH 5.5 and 7 — worth knowing before you decide whether a South Carolina soil test result is a problem or just a number. Drainage matters: this plant wants poorly (saturated >50% of year), well (dry spells). If your South Carolina site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.
Your land, not the state average
SSURGO maps about 21.6% of South Carolina as poorly or somewhat-poorly drained, and the class flips parcel to parcel. Clove has low drought tolerance, so it is the fast-draining end that will cost you — your soil map unit, not the state average, is the real answer.

What Else to Consider for Clove in South Carolina
Zone compatibility tells you about winter cold survival — but South Carolina growers also need to think about:
Red Piedmont clay requires amendment for drainage
High heat and humidity promote diseases
Hurricane risk along the coast
Growing clove here specifically
Clove roots run deep and prefer pH 4.5–8.0, but drainage comes first here: SSURGO maps about 21.6% of South Carolina as poorly or somewhat-poorly drained, and wet ground rots its crown before pH ever matters.
Plant clove on a raised, gravel-amended berm so water drains fast and the crown stays dry. How to handle it →
What to actually do about these — and the constraints that apply to every South Carolina grower, not just clove — is covered on the South Carolina growing guide.
Timing shifts within South Carolina
South Carolina isn't one climate. In Chester County, the last hard freeze (28°F) holds until about Mar 22 — roughly 14 days later than the recorded state median — so plant clove to your county's window, not the statewide date.
Clove needs about 150 days of frost-free season to complete its cycle. Even Chester County — South Carolina’s shortest season at 237 frost-free days — clears that by 87 days, so season length isn’t the constraint anywhere in South Carolina. What varies is your own parcel.
Across South Carolina’s 46 counties the frost-free season runs from 237 days in Chester County to 320 days in Charleston County — a spread of 83 days, which is why a single statewide planting date misleads. The median South Carolina county sees 265 frost-free days, leaving clove about 115 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"). Clove's 150-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Pollinator + Wildlife Value
Clove draws honeybees (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, clove can only work that bloom inside South Carolina's frost window — roughly 265 days, opening after the last 28°F freeze (Feb 27 - Mar 12) and closing at the first (Nov 23 - Dec 1), per NOAA Regional Climate Centers ACIS, 1991-2020.
Recommended Clove Varieties for South Carolina
South Carolina publishes no state variety trial for clove, so we won't invent a "best for South Carolina" list. Choose types rated to your USDA hardiness zone (7a-9b), and confirm winter survival and drainage against your own parcel.
South Carolina Cooperative Extension
For South Carolina-specific cultivar recommendations, planting calendars, and pest pressure for clove, the canonical source is Clemson Cooperative Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Common Questions About Growing Clove in South Carolina
When can I plant Clove in South Carolina?
South Carolina's last spring hard freeze (28°F) clears between Feb 27 and Mar 12, and the first fall hard freeze lands between Nov 23 and Dec 1 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Clove, so this page does not state whether it overwinters in South Carolina 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 Clove grown in across South Carolina?
South Carolina spans USDA hardiness zones 7a-9b (USDA ARS PHZM 2023). Clove carries a range of zones 11-12, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical South Carolina site have?
A typical South Carolina site sees ~265 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Clove needs 150+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date. In cooler counties like Chester, the freeze-free season runs shorter than the state average, so verify your own county's window.
How should I amend the soil for Clove in South Carolina?
Clove tolerates pH 4.5-8 and poorly (saturated >50% of year), well (dry spells) drainage (FAO ECOCROP). That is a 3.5-unit span, acid ground through alkaline, so pH is rarely what limits this plant on a South Carolina site — amend for drainage and organic matter first.
Will Clove actually grow on my specific land in South Carolina?
State-level zone + climate data is a sketch. A Growable Ground parcel report scores clove against your address's exact soil pH, drainage, sun, and frost-date data drawn from USDA SSURGO, NOAA, and PRISM — not state averages.
