Yes — Strong Match
chrysanthemum (zones 5-9) covers every zone Virginia contains (5b-8b), so hardiness is not what limits it anywhere in the state.
Your yard isn't the whole zone.
Virginia spans zones 5b-8b, but your yard has its own microclimate — slope, trees, and low spots shift frost and sun across a single parcel. Enter your address and we'll score chrysanthemum against your land's actual soil, sun, and frost.

When to Plant Chrysanthemum 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.
Frost tenderness
Chrysanthemum is frost-tender — its listed minimum temperature is 37.4°F (USDA PLANTS Database) — so set plants out two to three weeks PAST your local last hard freeze, not on it and not on the state's earliest date. The 28°F marker above is when killing freezes stop, not when light frost does.
When to start the seed
Those dates are when chrysanthemum goes out, not when it starts. It is sown under cover about 8 weeks ahead, so counting back from Virginia's late-side last freeze of Apr 2 is what fixes your sowing date — and a yard that clears frost earlier than the state's late date starts earlier still.
Timing tuned to sub-state frost dates — Highland 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 chrysanthemum survives winter here. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Chrysanthemum wants 180+ frost-free days; a typical Virginia site sees ~224 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves a workable window — start indoors to bank time.
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
Chrysanthemum likes near-neutral soil (pH 5.5-7.3). 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 and 6.5 — worth knowing before you decide whether a Virginia soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Virginia site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.
Your land, not the state average
Virginia's soils run mostly fine sandy loam, but SSURGO maps the series, texture, and drainage under your exact parcel. Chrysanthemum needs about 7 inches of workable depth, so it is that horizon — not the surface — you are testing for. That map unit, not the state average, decides how chrysanthemum performs.

Chrysanthemum in Virginia — Quick Answer
- Verdict: Yes — Strong Match
- Plant Zones: 5-9 (USDA PLANTS Database)
- State Zones: 5b-8b (USDA ARS PHZM 2023)
- Growing Season: 28°F hard freezes about Mar 22 - Apr 2 to Nov 2 - Nov 17 (NOAA Regional Climate Centers ACIS, 1991-2020)
What Else to Consider for Chrysanthemum 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
Growing chrysanthemum here specifically
Chrysanthemum needs pH 5.5–7.3; Virginia's dominant fine sandy loam soils may or may not deliver that, so your parcel's SSURGO map unit is the real test.
Start with a soil test on your own ground and adjust pH and texture to fit chrysanthemum's 5.5–7.3 range. How to handle it →
What to actually do about these — and the constraints that apply to every Virginia grower, not just chrysanthemum — is covered on the Virginia growing guide.
Timing shifts within Virginia
Virginia isn't one climate. In Highland County, the last hard freeze (28°F) holds until about Apr 27 — roughly 30 days later than the recorded state median — so plant chrysanthemum to your county's window, not the statewide date.
Chrysanthemum needs about 180 days of frost-free season to complete its cycle. 132 of Virginia’s 133 counties give it that outright. The tightest that does is Bath County at 190 frost-free days — 10 to spare. Below that line you are transplanting or extending the season, not direct-sowing.
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, leaving chrysanthemum about 44 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"). Chrysanthemum's 180-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 chrysanthemum (USDA PHZM 2023):
Pollinator + Wildlife Value
Chrysanthemum draws honeybees and butterflies (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, chrysanthemum 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.
Good to Know Before You Plant Chrysanthemum
Chrysanthemum is listed as toxic to dogs, cats (all) at a mild level (ASPCA). Most listed plants only cause brief upset — a raised bed or a fenced corner usually keeps curious pets clear. Worth knowing for placement: in Virginia this is a one-season plant and the first hard freeze (Nov 2 - Nov 17) takes it down, so the exposure above is a summer-long one rather than something standing in the bed all year.
Recommended Chrysanthemum Varieties for Virginia
Virginia publishes no state variety trial for chrysanthemum, so we won't invent a "best for Virginia" list. Choose types rated to your USDA hardiness zone (5b-8b), and confirm winter survival and drainage against your own parcel.

Common Questions About Growing Chrysanthemum in Virginia
When can I plant Chrysanthemum 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). Chrysanthemum is frost-tender — its listed minimum temperature is 37.4°F (USDA PLANTS Database) — so wait two to three weeks past your site's last hard freeze, when light frost has also stopped, before planting out.
What hardiness zone is Chrysanthemum grown in across Virginia?
Virginia spans USDA hardiness zones 5b-8b (USDA ARS PHZM 2023). Chrysanthemum carries a range of zones 5-9, 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). Chrysanthemum needs 180+ 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 Highland, the freeze-free season runs shorter than the state average, so verify your own county's window.
How should I amend the soil for Chrysanthemum in Virginia?
Chrysanthemum prefers pH 5.5-7.3 and 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 Chrysanthemum actually grow on my specific land in Virginia?
