Conditional — Some Areas
crowfoot grass (zones 8-12) reaches only part of New Jersey (6a-8a): zone 8 are in range, so where you are in the state decides it.
Your yard isn't the whole zone.
Crowfoot Grass is grown as an annual, so your winter zone isn't the deciding factor — your frost-free window is. A typical New Jersey site runs ~222 frost-free days, but that is a state median, not your yard: slope, trees, and low spots move the last-frost date across a single parcel. Enter your address and we'll score crowfoot grass against your land's actual frost dates, sun, and soil.

When to Plant Crowfoot Grass in New Jersey
The frost window
Across New Jersey, the last spring hard freeze (28°F) clears between Mar 26 and Apr 4, and the first fall hard freeze lands between Nov 5 and Nov 17 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 215-day window you can count on — up to 236 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
Crowfoot Grass is frost-tender — its listed minimum temperature is 50°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
Crowfoot Grass is direct-sown where it grows rather than started under cover, so there is no seed-tray head start to bank — New Jersey's dates above are the whole calendar for it. That makes the last-freeze date the binding constraint, and a warmer pocket of your own yard is worth more to this crop than it is to a transplanted one.
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 crowfoot grass survives winter in part of New Jersey, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Crowfoot Grass wants 90+ frost-free days; a typical New Jersey site sees ~222 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
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
Crowfoot Grass likes near-neutral soil (pH 6-8.3). That's the common-ground band across New Jersey's sandy loam (pine barrens) 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 7.5 — worth knowing before you decide whether a New Jersey soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your New Jersey site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

What Else to Consider for Crowfoot Grass in New Jersey
Zone compatibility tells you about winter cold survival — but New Jersey growers also need to think about:
Sandy Pine Barrens soils are nutrient-poor
Urban heat island effects in northern NJ
Deer browse is extreme in suburban areas
What to actually do about these — and the constraints that apply to every New Jersey grower, not just crowfoot grass — is covered on the New Jersey growing guide.
Timing shifts within New Jersey
Crowfoot Grass needs about 90 days of frost-free season to complete its cycle. Even Sussex County — New Jersey’s shortest season at 196 frost-free days — clears that by 106 days, so season length isn’t the constraint anywhere in New Jersey. What varies is your own parcel.
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"). Crowfoot Grass's 90-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
New Jersey Cooperative Extension
For New Jersey-specific cultivar recommendations, planting calendars, and pest pressure for crowfoot grass, the canonical source is Rutgers Cooperative Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Crowfoot Grass native to New Jersey?
No — the USDA PLANTS Database lists Crowfoot Grass as introduced rather than native in the Lower 48, so it is not part of New Jersey's native flora. It grows here as a garden plant; pairing it with a few New Jersey natives keeps local pollinators fed too.

Common Questions About Growing Crowfoot Grass in New Jersey
When can I plant Crowfoot Grass in New Jersey?
New Jersey's last spring hard freeze (28°F) clears between Mar 26 and Apr 4, and the first fall hard freeze lands between Nov 5 and Nov 17 (NOAA Regional Climate Centers ACIS, 1991-2020). Crowfoot Grass is frost-tender — its listed minimum temperature is 50°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 Crowfoot Grass grown in across New Jersey?
New Jersey spans USDA hardiness zones 6a-8a (USDA ARS PHZM 2023). Crowfoot Grass carries a range of zones 8-12, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical New Jersey site have?
A typical New Jersey site sees ~222 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Crowfoot Grass needs 90+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Crowfoot Grass native to New Jersey?
No — the USDA PLANTS Database lists Crowfoot Grass as introduced rather than native in the Lower 48, so it is not part of New Jersey's native flora. It grows here as a garden plant; pairing it with a few New Jersey natives keeps local pollinators fed too.
How should I amend the soil for Crowfoot Grass in New Jersey?
Crowfoot Grass prefers pH 6-8.3 and well (dry spells) drainage (FAO ECOCROP). That sits in the common-ground band across New Jersey soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
Will Crowfoot Grass actually grow on my specific land in New Jersey?
State-level zone + climate data is a sketch. A Growable Ground parcel report scores crowfoot grass against your address's exact soil pH, drainage, sun, and frost-date data drawn from USDA SSURGO, NOAA, and PRISM — not state averages.
