Conditional — Some Areas
amaranth greens (zones 2-11) has limited zone overlap with Vermont (3b-5b). Only zones 3-5 in the state are suitable.
Your yard isn't the whole zone.
Vermont spans zones 3b-5b, 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 amaranth greens against your land's actual soil, sun, and frost.

When to Plant Amaranth Greens in Vermont
The frost window
Across Vermont, the last spring frost clears between May 5 and Jun 1, and the first fall frost lands between Sep 10 and Oct 5 (NOAA Climate Normals 1991-2020). Counting from the latest last frost to the earliest first frost, that's a 101-day window you can count on — up to 153 days on a mild site in a kind year.
Frost tenderness
Amaranth Greens is frost-tender — its listed minimum temperature is 46.4°F (USDA PLANTS Database) — so set plants out after the last frost has cleared your local site, not the state's earliest date.
Days to maturity vs. the window
At 45 days to maturity (USDA PLANTS Database), a planting right after last frost ripens with 56 days to spare even in Vermont's tightest frost scenario — room for a later start or a second sowing.
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
Zone compatibility says you can survive winter here. Whether the growing season is long enough — and warm enough — is a different question.
Frost-free days
Amaranth Greens wants 30+ frost-free days; a typical Vermont site sees ~150 (NOAA Climate Normals). That leaves comfortable headroom for succession planting.
Growing degree days
Amaranth Greens needs ~1000 GDD (base 50°F) to ripen. The state median runs ~2700 GDD (USDA NRCS county aggregates), so Vermont's typical season clears that easily.
Climate aggregates derive from USDA NRCS county-level hardiness data + Cornell CALS Extension GDD-by-region tables + MSU Extension chill-hours-by-zone (1991-2020 NOAA Climate Normals baseline).
Soil + Drainage Fit
Amaranth Greens likes near-neutral soil (pH 4.3-8). That's the common-ground band across Vermont's glacial till and clay — a soil test confirms it for your site. Drainage matters: this plant wants well (dry spells). If your Vermont site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

- Plant Zones: 2-11 (USDA PLANTS Database)

What Else to Consider
Zone compatibility tells you about winter cold survival — but Vermont growers also need to think about:
Short growing season (100-130 frost-free days)
Indoor starts, fast varieties, and a cold frame on each shoulder — the Vermont formula for making 110 days feel like 150.
Rocky soils throughout the Green Mountains
Raised beds spare you the stone harvest — build up over cleared ground and plant the same weekend.
Heavy clay in the Champlain Valley
Champlain clay holds spring water late — raised or mounded beds dry out and warm up weeks earlier for planting.

Is Amaranth Greens native to Vermont?
No — the USDA PLANTS Database lists Amaranth Greens as introduced rather than native in the Lower 48, so it is not part of Vermont's native flora. It grows here as a garden plant; pairing it with a few Vermont natives keeps local pollinators fed too.

Common Questions About Growing Amaranth Greens in Vermont
When can I plant Amaranth Greens in Vermont?
Vermont's last spring frost clears between May 5 and Jun 1, and the first fall frost lands between Sep 10 and Oct 5 (NOAA Climate Normals 1991-2020). Amaranth Greens is frost-tender — its listed minimum temperature is 46.4°F (USDA PLANTS Database) — so wait until the last frost has cleared your specific site before planting out.
Can Amaranth Greens mature before first frost in Vermont?
Yes — Amaranth Greens matures in 45 days (USDA PLANTS Database), and Vermont's dependable frost-free window runs 101 days (NOAA Climate Normals 1991-2020), leaving 56 days of margin. Plant just after last frost and it ripens ahead of the first fall frost.
What hardiness zone is Amaranth Greens grown in across Vermont?
Vermont spans USDA hardiness zones 3b-5b (USDA ARS PHZM 2023). Amaranth Greens carries a range of zones 2-11, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Vermont site have?
A typical Vermont site sees ~150 frost-free days per year (derived from NOAA Climate Normals 1991-2020). Amaranth Greens needs 30+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Amaranth Greens native to Vermont?
No — the USDA PLANTS Database lists Amaranth Greens as introduced rather than native in the Lower 48, so it is not part of Vermont's native flora. It grows here as a garden plant; pairing it with a few Vermont natives keeps local pollinators fed too.
How should I amend the soil for Amaranth Greens in Vermont?
Amaranth Greens prefers pH 4.3-8 and well (dry spells) drainage (USDA PLANTS Database). That sits in the common-ground band across Vermont soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
