Generally — Most Areas
Turks cap (zones 7-11) suits most of Virginia (5b-8b) — zones 7-8 are in range, and the rest of the state is the exception.
Your yard isn't the whole zone.
Virginia spans zones 5b-8b, 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 turks cap against your parcel's actual hardiness, soil, and sun.

When to Plant Turks Cap in Virginia
The frost window
Across Virginia, the last spring hard freeze (28°F) clears between Mar 22 and Apr 2, and the first fall hard freeze lands between Nov 2 and Nov 17 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 214-day window you can count on — up to 240 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
Virginia runs as cold as USDA zone 5, and no sourced winter-hardiness floor is on record for turks cap, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether turks cap is a permanent planting or a replant-every-spring crop for you turns on your own zone within Virginia; 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 turks cap survives winter in part of Virginia, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Turks Cap wants 365+ frost-free days; a typical Virginia site sees ~224 (NOAA Regional Climate Centers ACIS, 1991-2020) — 141 days short of what it needs. A typical Virginia season does not carry this crop to harvest outdoors, and a gap that size is not one an earlier sowing date or a faster cultivar closes; growing it here means growing it under cover.
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
Turks Cap likes near-neutral soil (pH 6-8.5). That's the common-ground band across Virginia's red clay (piedmont) and silt loam — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 6.5 and 8 — worth knowing before you decide whether a Virginia 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 Virginia site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

What Else to Consider for Turks Cap in Virginia
Zone compatibility tells you about winter cold survival — but Virginia growers also need to think about:
Heavy Piedmont red clay requires amendment
Humidity and heat in summer promote disease
Deer pressure is heavy in suburban and rural areas
What to actually do about these — and the constraints that apply to every Virginia grower, not just turks cap — is covered on the Virginia growing guide.
Timing shifts within Virginia
Turks Cap needs about 365 days of frost-free season to complete its cycle. No Virginia county gives it that outdoors: even Hampton County, the state’s longest season at 289 frost-free days, falls 76 days short — so it needs transplants, a short-season variety, or covered growing.
Across Virginia’s 133 counties the frost-free season runs from 176 days in Highland County to 289 days in Hampton County — a spread of 113 days, which is why a single statewide planting date misleads. The median Virginia county sees 224 frost-free days, which is 141 days short of what turks cap needs — so on a typical Virginia parcel this is a transplant-or-protect crop, not a direct-sow one.
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"). Turks Cap's 365-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Where in Virginia Fits Best
Even within Virginia's zones 5b-8b, county microclimates differ enough to change what thrives. These counties carry the closest zone match for turks cap (USDA PHZM 2023):
Pollinator + Wildlife Value
Turks Cap draws hummingbirds and butterflies (high value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, turks cap can only work that bloom inside Virginia's frost window — roughly 224 days, opening after the last 28°F freeze (Mar 22 - Apr 2) and closing at the first (Nov 2 - Nov 17), per NOAA Regional Climate Centers ACIS, 1991-2020.

Common Questions About Growing Turks Cap in Virginia
When can I plant Turks Cap in Virginia?
Virginia's last spring hard freeze (28°F) clears between Mar 22 and Apr 2, and the first fall hard freeze lands between Nov 2 and Nov 17 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Turks Cap, so this page does not state whether it overwinters in Virginia 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 Turks Cap grown in across Virginia?
Virginia spans USDA hardiness zones 5b-8b (USDA ARS PHZM 2023). Turks Cap carries a range of zones 7-11, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Virginia site have?
A typical Virginia site sees ~224 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Turks Cap needs 365+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
How should I amend the soil for Turks Cap in Virginia?
Turks Cap prefers pH 6-8.5 and poorly (saturated >50% of year), well (dry spells) drainage (FAO ECOCROP). That sits in the common-ground band across Virginia soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
Will Turks Cap actually grow on my specific land in Virginia?
