When to Plant Scarlet Runner Bean in West Virginia

The frost window

Across West Virginia, the last spring hard freeze (28°F) clears between Apr 4 and Apr 15, and the first fall hard freeze lands between Oct 26 and Nov 5 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 194-day window you can count on — up to 215 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

West Virginia runs as cold as USDA zone 5, and no sourced winter-hardiness floor is on record for scarlet runner bean, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether scarlet runner bean is a permanent planting or a replant-every-spring crop for you turns on your own zone within West 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 scarlet runner bean survives winter in part of West Virginia, not across all of it. Whether the season is long enough — and warm enough — is a different question.

Frost-free days

Scarlet Runner Bean wants 70+ frost-free days; a typical West Virginia site sees ~204 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.

Growing degree days

Scarlet Runner Bean needs ~900 GDD (base 50°F) to ripen. The state median runs ~2941 GDD (from PRISM 1991-2020 climate normals), so West Virginia's typical season clears that easily.

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

Scarlet Runner Bean likes near-neutral soil (pH 5.5-7.5). That's the common-ground band across West Virginia's shale-derived and sandy loam — 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 West Virginia soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your West Virginia site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

What Else to Consider for Scarlet Runner Bean in West Virginia

Zone compatibility tells you about winter cold survival — but West Virginia growers also need to think about:

Steep terrain limits usable growing area

Thin acidic soils over shale bedrock

Short mountain valley growing seasons

What to actually do about these — and the constraints that apply to every West Virginia grower, not just scarlet runner bean — is covered on the West Virginia growing guide.

Timing shifts within West Virginia

Scarlet Runner Bean needs about 70 days of frost-free season to complete its cycle. Even Pocahontas County — West Virginia’s shortest season at 170 frost-free days — clears that by 100 days, so season length isn’t the constraint anywhere in West Virginia. What varies is your own parcel.

Across West Virginia’s 55 counties the frost-free season runs from 170 days in Pocahontas County to 232 days in Logan County — a spread of 62 days, which is why a single statewide planting date misleads. The median West Virginia county sees 204 frost-free days, leaving scarlet runner bean about 134 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"). Scarlet Runner Bean's 70-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.

Where in West Virginia Fits Best

Even within West Virginia's zones 5b-7a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for scarlet runner bean (USDA PHZM 2023):

Pollinator + Wildlife Value

Scarlet Runner Bean draws honeybees, native bees, and hummingbirds (high value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, scarlet runner bean can only work that bloom inside West Virginia's frost window — roughly 204 days, opening after the last 28°F freeze (Apr 4 - Apr 15) and closing at the first (Oct 26 - Nov 5), per NOAA Regional Climate Centers ACIS, 1991-2020.

West Virginia Cooperative Extension

For West Virginia-specific cultivar recommendations, planting calendars, and pest pressure for scarlet runner bean, the canonical source is WVU Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.

Is Scarlet Runner Bean native to West Virginia?

No — the USDA PLANTS Database lists Scarlet Runner Bean as introduced rather than native in the Lower 48, so it is not part of West Virginia's native flora. It grows here as a garden plant; pairing it with a few West Virginia natives keeps local pollinators fed too.

Common Questions About Growing Scarlet Runner Bean in West Virginia

When can I plant Scarlet Runner Bean in West Virginia?

West Virginia's last spring hard freeze (28°F) clears between Apr 4 and Apr 15, and the first fall hard freeze lands between Oct 26 and Nov 5 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Scarlet Runner Bean, so this page does not state whether it overwinters in West 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 Scarlet Runner Bean grown in across West Virginia?

West Virginia spans USDA hardiness zones 5b-7a (USDA ARS PHZM 2023). Scarlet Runner Bean 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 West Virginia site have?

A typical West Virginia site sees ~204 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Scarlet Runner Bean needs 70+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.

Is Scarlet Runner Bean native to West Virginia?

No — the USDA PLANTS Database lists Scarlet Runner Bean as introduced rather than native in the Lower 48, so it is not part of West Virginia's native flora. It grows here as a garden plant; pairing it with a few West Virginia natives keeps local pollinators fed too.

How should I amend the soil for Scarlet Runner Bean in West Virginia?

Scarlet Runner Bean prefers pH 5.5-7.5 and well (dry spells) drainage (Growable Ground Plant Database). That sits in the common-ground band across West Virginia soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
