Generally — Most Areas
autumn sage (zones 7-9) suits most of New Jersey (6a-8a) — zones 7-8 are in range, and the rest of the state is the exception.
Your yard isn't the whole zone.
New Jersey spans zones 6a-8a, but your yard sits in exactly one — and slope, tree cover, and cold-air pockets nudge it further. Enter your address and we'll score autumn sage against your parcel's actual hardiness, soil, and sun.

When to Plant Autumn Sage 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 autumn sage, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether autumn sage 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.
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 autumn sage 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
Autumn Sage wants 120+ 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
Autumn Sage tolerates a wide pH range (pH 4.2-8.3) — 4.1 units, acid ground through alkaline — so soil acidity is rarely what limits it in New Jersey. A soil test is still worth having, but for what else it tells you about this site, not to clear this plant. It will grow across that whole span, but it does best between pH 5 and 6.5 — 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 Autumn Sage 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 autumn sage — is covered on the New Jersey growing guide.
Timing shifts within New Jersey
Autumn Sage needs about 120 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 76 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"). Autumn Sage's 120-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Where in New Jersey Fits Best
Even within New Jersey's zones 6a-8a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for autumn sage (USDA PHZM 2023):
Pollinator + Wildlife Value
Autumn Sage draws honeybees, native bees, butterflies, and hummingbirds (high value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, autumn sage 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 autumn sage, the canonical source is Rutgers Cooperative Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Autumn Sage native to New Jersey?
Autumn Sage is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in New Jersey. It can still earn a place in a New Jersey garden — the zone comparison above tells you whether it will thrive.

Common Questions About Growing Autumn Sage in New Jersey
When can I plant Autumn Sage 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 Autumn Sage, 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 Autumn Sage grown in across New Jersey?
New Jersey spans USDA hardiness zones 6a-8a (USDA ARS PHZM 2023). Autumn Sage carries a range of zones 7-9, 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). Autumn Sage needs 120+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Autumn Sage native to New Jersey?
Autumn Sage is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in New Jersey. It can still earn a place in a New Jersey garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Autumn Sage in New Jersey?
Autumn Sage tolerates pH 4.2-8.3 and well (dry spells) drainage (FAO ECOCROP). That is a 4.1-unit span, acid ground through alkaline, so pH is rarely what limits this plant on a New Jersey site — amend for drainage and organic matter first.
