New Jersey is not one climate
New Jersey’s winter-low ladder runs across 21 counties, from zone 6.5 in Morris County to zone 7.5 in Salem County. That is 10°F between the two counties’ average coldest night — the difference between cornelian cherry overwintering in the ground and coming under cover.
The middle half of 21 counties runs 7–7 zones, with a median of 7 zones — a 1-zone span end to end.

When to Plant Cornelian Cherry 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.
Winter standing
New Jersey runs as cold as USDA zone 6, and no sourced winter-hardiness floor is on record for cornelian cherry, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether cornelian cherry is a permanent planting or a replant-every-spring crop for you turns on your own zone within New Jersey; check its hardiness range against that before treating it as long-lived ground.
Timing tuned to sub-state frost dates — Morris County, not the statewide average.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: Growable Ground Plant Database — frost-free days from FAO ECOCROP, days to harvest from university Extension production guides, and growing-degree-day and chill-hour minimums that are compilation estimates rather than published figures. 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 cornelian cherry survives winter here. Whether the season is long enough — and warm enough — is a different question.
Growing degree days
Cornelian Cherry needs ~1500 GDD (base 50°F) to ripen. The state median runs ~3340 GDD (from PRISM 1991-2020 climate normals), so New Jersey's typical season clears that easily.
Chill hours
Cornelian Cherry requires ~600 chill hours (32-45°F dormancy window). New Jersey typically banks ~2500 chill hours per winter (from PRISM 1991-2020 climate normals), which keeps this plant on track.
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
Cornelian Cherry likes near-neutral soil (pH 6-8.5). 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 8 — 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.
Your land, not the state average
SSURGO maps about 14.3% of New Jersey as poorly or somewhat-poorly drained, and the class flips parcel to parcel. Cornelian Cherry has low drought tolerance, so it is the fast-draining end that will cost you — your soil map unit, not the state average, is the real answer.

Before you plant cornelian cherry for food
Anything you grow to eat takes up what is in the ground it grows in, so what is on record near you is worth knowing before cornelian cherry goes in. What follows is New Jersey’s documented federal record at state scale — a screening signal, not a soil test, and not a statement about any one lot.
Safe to Grow Here?
What the federal record shows across New Jersey — and how to grow with it.
We checked the federal record across New Jersey — 41,663 documented sites across 7 of the 9 source types we track.
The most significant on record: 877 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
New Jersey carries one of the heavier federal records we track — and that's not a verdict on your yard. Proximity to a documented site is information, not a diagnosis: nothing here says any particular parcel is affected. It does earn one concrete step — before food beds go in the ground, a professional soil test tells you exactly what you're working with, and raised beds with clean imported soil grow well almost anywhere in the meantime.

What Else to Consider for Cornelian Cherry 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
Growing cornelian cherry here specifically
Cornelian Cherry likes pH 6.0–8.5 and its growing tissue burns around -20°F (FAO ECOCROP), yet neither saves it from wet feet — SSURGO maps about 14.3% of New Jersey poorly-drained, where its crown sit and rot.
Set cornelian cherry high on bermed, grit-amended ground so winter and storm water drain away from the crown. How to handle it →
What to actually do about these — and the constraints that apply to every New Jersey grower, not just cornelian cherry — is covered on the New Jersey growing guide.
Timing shifts within New Jersey
New Jersey isn't one climate. In Morris County, the last hard freeze (28°F) holds until about Apr 11 — roughly 11 days later than the recorded state median — so plant cornelian cherry to your county's window, not the statewide date.
County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). A parcel report resolves your address's own frost dates.
Where in New Jersey Cornelian Cherry Is Zone-Hardy
Cornelian Cherry is rated for USDA zones 5–11. Every one of New Jersey’s 21 counties sits inside that band — from Morris County at zone 6b to Salem County at zone 7b — so winter cold is not what decides this plant anywhere in the state. What is left to vary is your own parcel: slope, shelter and cold-air drainage routinely move a site half a zone either way from the county figure.
Across those 21 counties New Jersey’s winter-low ladder runs from zone 6b in Morris County to zone 7b in Salem County — 1 USDA zone of spread, which is 10°F between the two counties’ average coldest night of the year. That is why a statewide hardiness answer is where you start and not where you finish.
The planting window moves with it. Sussex County holds its last hard freeze (28°F) until about Apr 11, while Salem County is clear by Mar 20 — 22 days apart. Set cornelian cherry out on your county’s date, not the state’s.
County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F killing freeze — earlier than the folk 32°F "last frost". Cornelian Cherry’s zone 5–11 band: USDA PLANTS / Growable Ground plant database. A parcel report resolves your address’s own zone and frost dates rather than its county’s.
Pollinator + Wildlife Value
Cornelian Cherry draws honeybees, native bees, and butterflies (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, cornelian cherry can only work that bloom inside New Jersey's frost window — roughly 222 days, opening after the last 28°F freeze (Mar 26 - Apr 4) and closing at the first (Nov 5 - Nov 17), per NOAA Regional Climate Centers ACIS, 1991-2020.
New Jersey Cooperative Extension
For New Jersey-specific cultivar recommendations, planting calendars, and pest pressure for cornelian cherry, the canonical source is Rutgers Cooperative Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Cornelian Cherry native to New Jersey?
No — the USDA PLANTS Database lists Cornelian Cherry 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 Cornelian Cherry in New Jersey
When can I plant Cornelian Cherry 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). No sourced winter-hardiness floor is on record for Cornelian Cherry, so this page does not state whether it overwinters in New Jersey 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 Cornelian Cherry grown in across New Jersey?
New Jersey spans USDA hardiness zones 6a-8a (USDA ARS PHZM 2023). Cornelian Cherry carries a range of zones 5-11, 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). Cornelian Cherry should be matched against that window, so check whether your local microclimate runs above or below the state average before settling on a planting date. In cooler counties like Morris, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Cornelian Cherry native to New Jersey?
No — the USDA PLANTS Database lists Cornelian Cherry 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 Cornelian Cherry in New Jersey?
Cornelian Cherry prefers pH 6-8.5 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.
