Can I Grow Goumi in Arkansas?

Goumi in Arkansas — the short answer

Arkansas is not one climate

Where in Arkansas Fits Best

Even within Arkansas's zones 6b-8b, county microclimates differ enough to change what thrives. These counties carry the closest zone match for goumi (USDA PHZM 2023):

Zone Comparison

Plant data: Growable Ground Plant Database, compiled from FAO ECOCROP, USDA PLANTS, and university Extension sources — per-field provenance varies and is published with the dataset. State data: USDA ARS PHZM 2023, NOAA Climate Normals, NRCS SSURGO.

When to Plant Goumi in Arkansas

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 goumi survives winter here. Whether the season is long enough — and warm enough — is a different question.

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

Goumi likes near-neutral soil (pH 6-8.5). That's the common-ground band across Arkansas's silt loam and sandy 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 Arkansas soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Arkansas site is heavier clay or sits in a low spot, a raised bed lifts the roots above wet ground, or work in compost. pH range, preferred pH and drainage need: We haven't confirmed this against a published source yet.

Before you plant goumi 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 goumi goes in. What follows is Arkansas’s documented federal record at state scale — a screening signal, not a soil test, and not a statement about any one lot.

What Else to Consider for Goumi in Arkansas

Zone compatibility tells you about winter cold survival — but Arkansas growers also need to think about:

What to actually do about these — and the constraints that apply to every Arkansas grower, not just goumi — is covered on the Arkansas growing guide.

Where in Arkansas Goumi Is Zone-Hardy

Goumi is rated for USDA zones 4–8. 62 of Arkansas’s 75 counties fall inside that band. The coldest that does is Benton County at zone 7a. 13 counties sit above its zone 8 ceiling, where the limit is too little winter chill rather than too much cold. Where you are in Arkansas decides this one.

Across those 75 counties Arkansas’s winter-low ladder runs from zone 7a in Benton County to zone 8b in Union County — 1.5 USDA zones of spread, which is 15°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. Carroll County holds its last hard freeze (28°F) until about Mar 26, while Chicot County is clear by Feb 19 — 35 days apart. Set goumi 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". Goumi’s zone 4–8 band: Not verified. A parcel report resolves your address’s own zone and frost dates rather than its county’s.

Pollinator + Wildlife Value

Goumi draws honeybees and native bees (moderate value). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, goumi can only work that bloom inside Arkansas's frost window — roughly 254 days, opening after the last 28°F freeze (Mar 2 - Mar 20) and closing at the first (Nov 15 - Nov 23), per NOAA Regional Climate Centers ACIS, 1991-2020. Pollinator value: We haven't confirmed this against a published source yet.

Arkansas Cooperative Extension

For Arkansas-specific cultivar recommendations, planting calendars, and pest pressure for goumi, the canonical source is University of Arkansas Cooperative Extension Service. Their fact sheets carry the local trial data we can't generalize across 50 states.

Is Goumi native to Arkansas?

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

Looking for plants that belong here? The Arkansas growing guide lists plants that USDA PLANTS records growing in Arkansas and that Kew and NatureServe Explorer both list in its native range, leaving out any that NatureServe flags as exotic there or that our audit holds.
