USDA zone 7a in Virginia

0 to 5 °F avg. annual extreme minimum · 62 locations in this group · NOAA 1991–2020 normals

USDA plant hardiness zone 7a covers 62 locations across Virginia (average annual extreme minimum 0 to 5 °F): Ashburn, VA, Atkins, VA, Barboursville, VA, Blacksburg, VA, Bland, VA, Bristol, VA, and 56 more. Average last spring frost across this group ranges March 28 (Independent Hill) to May 9 (Atkins), and growing seasons run 150–226 days (Atkins to Independent Hill) — even within one state, because hardiness sets winter survival, not planting dates. The table below gives every Virginia location's own frost dates; the printable planting calendar uses Dooms, this group's median-season location.

* Dooms is this group's median-season location — the calendar below is computed from its data.

Data: NOAA NCEI U.S. Climate Normals 1991–2020 (public domain) and USDA Plant Hardiness Zone Map 2023. Planting windows synthesized from U.S. Cooperative Extension guides.

Planting calendar (Dooms, representative)

Computed from Dooms's average frost dates — the median-season location in this Virginiazone 7a group. hatched = start seeds indoors, solid green = plant out, teal = a fall sowing, and the terracotta dot marks the estimated first harvest. Ranges are extension-guide planning guidance, not guarantees — your own location's dates may run a week or two earlier or later (see the table above).

Which crops fit this growing season

Using Dooms's own 184-day growing season (32°F, NOAA 1991–2020 median) against each crop's real days-to-maturity range: 12 of 12 crops mature here with comfortable margin. A different location in the table above with a longer or shorter season will get a different mix — the ZIP planner on the home page gives your own.

Frost & freeze dates (Dooms)

From NOAA's 1991–2020 Climate Normals at station USC00448941. The median (p50) is the average date; the 90%-safe column is the date the freeze has passed in about 9 years out of 10 — the conservative date to plant after or harvest before.

Growing degree days

Growing degree days (GDD) accumulate warmth above a base temperature over the year — a better predictor of crop development than the calendar alone. This group's median GDD (base 50°F) across all 62 locations is 3,453; Dooms's own reading is shown below.

Hardiness zone 7a in Virginia

Zone 7a means an average annual extreme minimum winter temperature of about 0 to 5 °F on the USDA's 2023 map — the number that tells you which perennials, shrubs, and trees reliably survive an average winter here. It does not set your planting dates, which come from the frost calendar above. Virginia spans 6 hardiness zones in this dataset — see all Virginia locations for the full range, including zones6a, 6b, 7b, 8a, 8b.

Frequently asked questions

What does USDA hardiness zone 7a mean in Virginia?
Zone 7a means an average annual extreme minimum winter temperature of 0 to 5 °F — the standard USDA measure of which perennials survive winter. 62 locations in Virginia fall in this zone. It does not set planting dates; see the frost calendar below for that.
Where in Virginia's zone 7a is the growing season longest?
Independent Hill runs the longest season on this page at about 226 days; Atkins is shortest at about 150 days — they share the same hardiness zone, but they sit at different weather stations, so their frost calendars differ.
When should I plant tomatoes in Virginia's zone 7a?
Using Dooms's frost dates (this page's median-season location): start seeds indoors about Feb 24 – Mar 10, then transplant outside about Apr 28 – May 5. Your own location in the table above may differ by a week or two — use the ZIP planner on the home page for your exact station's dates.
Does every location in Virginia's zone 7a have the same frost dates?
No — they do not all share a weather station, so frost dates vary by a week or more across the 62 locations listed (see the table above for each location's own dates).

Sources & method

Frost, freeze, growing-season, and growing-degree-day figures are NOAA NCEI U.S. Climate Normals 1991–2020, one reading per location's own nearest station (see the table above). The hardiness zone is the USDA Plant Hardiness Zone Map 2023, matched to each location's ZIP. Planting windows are computed by counting from the average last and first frost using per-crop offsets synthesized from U.S. Cooperative Extension guides — the full method and citations are on the methodology page.
